 Specification

 Lightning protection device, lightning protection device, lightning protection system, lightning power utilization device, lightning power utilization system, wind power generation device and wind power generation system

 [0001] The present invention relates to a device or system that prevents or uses lightning strikes, and for example, guides the direction of lightning strikes and protects buildings, wind power generators, or buildings such as ships from lightning strikes. A lightning striker and lightning prevention system, a lightning power utilization device and lightning power utilization system that uses lightning power, a rotating blade rotating by wind power to generate electricity and generating lightning prevention functions The present invention relates to a wind power generation apparatus and a wind power generation system.

 Background art

 Conventionally, it is known that lightning is likely to fall on tall objects such as trees, steel towers, and buildings. As a method of preventing tall buildings from lightning strikes, a method has been proposed in which a lightning rod that is taller than the one to be protected from lightning strikes is installed. (See Patent Document 1).

 According to this lightning rod, lightning can be dropped onto the lightning rod, and the structure to be protected from lightning can be protected from lightning.

 [0003] However, in order to prevent a lightning strike with a lightning rod, it is necessary to construct and install a lightning rod that is taller than the building to be protected from lightning. And if the building to be protected from lightning strike is a wind power generator with a height of 100m, for example, it would be very expensive to install a lightning rod with a taller height than this. There was a problem.

 [0004] Conventionally, it is known that lightning has a very strong power, and that when lightning strikes, human lives are lost and electronic devices are destroyed. In order to prevent such a strong lightning from falling, a method of installing a lightning rod higher than a building to be protected such as a building has been proposed (see Patent Document 1). According to this lightning rod, lightning can be dropped on the lightning rod, and the structure to be protected from lightning can be protected from lightning.

[0005] However, the above-described method only protects devices and the like by avoiding lightning, and lightning has. It wasn't taken into account at all!

 [0006] Conventionally, there has been provided a wind turbine generator that generates power by rotating a rotor blade with wind power and converting the rotational force into electricity. This wind turbine generator is attracting attention as a tailor-made generator from the viewpoint of environmental protection.

 [0007] In such a wind power generator, in order to receive wind power sufficiently, it is necessary to increase the size of the rotor blades, and it is preferable to install the rotor blades at a certain height from the ground. For this reason, the wind power generators currently in use are very tall, with a height of about 100m. In addition, wind power generators are often installed in places with few structures such as plateaus in order to receive the natural wind.

 However, when a tall wind power generation apparatus is installed in a place with few structures as described above, there is a problem that the possibility of direct lightning strikes increases. If lightning strikes directly, it will lead to failure of the wind turbine generator. As a method for preventing such a lightning strike, a method of attaching a lightning rod near the wind power generator and causing this lightning rod to strike a lightning has been proposed (see Patent Document 1).

 [0009] However, in order to prevent a lightning strike with a lightning rod, it is necessary to construct and install a lightning rod that is taller than a wind power generator, which is very expensive.

 As described above, there are various problems regarding the prevention and use of lightning strikes.

 BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described below with reference to the drawings.

 Example 1

 FIG. 1 is a configuration diagram showing a schematic configuration of the lightning arrester 1.

 The lightning striker 1 is composed of a positive charging unit 2a and a negative charging unit 2b.

[0030] In the positive charging unit 2a, an outer wall 3a is provided in the entire casing, and a corona discharge device 4a is provided therein.

[0031] The corona discharge device 4a discharges corona toward the top plate of the outer wall 3a, and charges the top plate of the outer wall 3a to the brass. As a result, the outer wall 3a is charged positively, and in particular, the top plate portion is charged positively. The positive charging of the positive charging unit 2a may be charged to about + 200V, for example.

[0032] In the negative charging unit 2b, an outer wall 3b is provided in the entire casing, and a corona discharge device 4b is provided therein. [0033] The corona discharge device 4b performs corona discharge toward the top plate of the outer wall 3b, and negatively charges the top plate of the outer wall 3b. As a result, the outer wall 3b is negatively charged, and in particular, the top plate portion is negatively charged. The negative charging of the negative charging unit 2b may be charged, for example, to about 200V.

 [0034] These positive charging and negative charging may be executed when a lightning strike may occur due to a thundercloud or the like. Therefore, the lightning striker 1 is provided with an input unit such as a push button (not shown). When the input unit receives an execution start input, the positive charging unit 2a is positively charged and the negative charging unit 2b is negatively charged. It may be configured to perform charging.

 FIG. 2 is a block diagram showing a schematic configuration of the lightning arrester 1.

 The lightning striker 1 is provided with one power supply unit 6. The power supply unit 6 supplies power to both the corona discharge device 4a and the corona discharge device 4b. This simplifies the system with a single power source. In other words, both the corona discharge device 4a and the corona discharge device 4b are driven by a single operation of starting power supply from the power supply unit 6 in addition to the need for only one power supply unit 6, and each switch is turned on and off. Can be eliminated.

 [0036] The corona discharge mechanism of the corona discharge device 4a and the corona discharge device 4b is provided with an electrode needle composed of a pointed needle on each of the corona discharge device 4a and the corona discharge device 4b. By applying a high voltage from the power supply unit 6, a well-known mechanism for releasing corona and discharging corona discharge can be used.

 FIG. 3 is an explanatory diagram for explaining the configuration of the lightning strike prevention system 9 and the state of lightning strikes.

 The lightning protection system 9 is configured by installing the above described lightning protection device 1 and providing an insulating member 8 on the installation surface of the building K to be protected from lightning! The insulating member 8 is formed with a sufficient thickness to block lightning by a rubber material having sufficient strength. The insulating member 8 keeps the building K electrically floating from the ground A, and protects the electronic equipment of the building K from the surge voltage that hits the ground A during lightning strikes.

[0038] When there is a risk of lightning due to thunderclouds, etc., the power supply 6 of the lightning striker 1 is turned on, and the corona discharge devices 4a and 4b are forced toward the outer walls 3a and 3b. And negative discharge, the outer wall 3a is positively charged (eg + 200V), and the outer wall 3b is The battery is charged (eg -200V).

[0039] Since the building K, which is subject to lightning protection, is located at a position sufficiently higher than the ground A, when it is discharged to the ground A from a thundercloud charged to tens of thousands to 100 million V, it is normal. Closest to thundercloud

Lightning strikes V, building κ.

[0040] Here, lightning includes positive and negative lightning, and the lightning T falling from the thundercloud above to the ground A is almost always negative.

 For this reason, it attracts to the outer wall 3a of the positive charging unit 2a that is positively charged, and lightning T falls on the outer wall 3a.

[0041] If the positive charge of the outer wall 3a is weak, there remains a risk of a lightning strike on the building K. However, since it is sufficiently strongly charged, for example, + 200V, lightning T can be guided to the outer wall 3a instead of the building K and dropped on the outer wall 3a.

[0042] If lightning T is a positive lightning, lightning strikes the outer wall 3b of the negatively charged unit 2b, which is negatively charged. Again, building K can be protected from lightning strikes.

[0043] In this way, regardless of whether the lightning is positive or negative, it is a lightning protection target building.

K can be reliably protected from lightning.

 Since the lightning strike device 1 of the present embodiment is a single device that includes the positive charging unit 2a and the negative charging unit 2b as a set, the user is more positive in the nature of the lightning falling at the installation site where lightning is to be prevented. Even without knowing the negative power, it is possible to drop lightning onto the lightning striker 1 simply by installing and operating the lightning striker 1, and protect the lightning protection target such as the building K from lightning strikes.

 Example 2

 FIG. 4 is a configuration diagram showing a schematic configuration of the lightning arrester 10 of the second embodiment.

 The lightning striker 10 is provided with a positive charging blade 1 l a and a negative charging blade 1 lb that are rotated by the driving force of the driving unit 14 composed of a motor or the like!

[0045] Insulating shafts 13a and 13b that are rotated by the driving unit 14 are provided for the driving unit 14, and the insulating shafts 13a and 13b, the positive charging blade 11a, and the negative charging blade l ib are interposed between the driving shafts 14a and 13b. Shafts 12a and 12b are provided, respectively. Therefore, the rotational force by the drive unit 14 is applied to the positive charging blade 1 la and the insulating shafts 13a and 13b and the shafts 12a and 12b. Negatively charged blade is transmitted to 1 lb.

 FIG. 5 is a cross-sectional view showing the configuration of the positive charging blade 11a and the negative charging blade l ib.

 As shown in FIG. 5 (A), the positive charging blade 11a is provided with an insulating layer 22 made of rubber or the like on the entire outer periphery of a casing 21 made of a hard member such as metal. A positively charged layer 23a is provided on the entire circumference. The positively charged layer 23a is made of a material such as nylon that is positively charged when exposed to wind. For this reason, the positively charged blade 11a always positively charges the positively charged layer 23a while rotating. In addition, an insulating layer 22 is provided throughout the positively charged layer 23a. For this reason, the positive charging blade 11 a can prevent the charged positive charge from being discharged through the lightning arrester 10. Therefore, the positive charging blade 11a can be positively charged efficiently.

 [0047] As shown in FIG. 5 (B), the negatively charged blade l ib is provided with an insulating layer 22 made of rubber or the like on the entire outer periphery of a casing 21 made of a hard member such as metal. A negatively charged layer 23 b is provided on the entire outer periphery of the layer 22. The negatively charged layer 23b is made of a material such as polyester or leather that is negatively charged when exposed to wind. For this reason, while the negative charging blade l ib is rotating, the negative charging layer 23b is always negatively charged. In addition, an insulating layer 22 is provided throughout the negatively charged layer 23b. Therefore, the negative charging blade l ib can prevent the charged negative charge from being discharged through the lightning arrester 10. Therefore, the negative charging blade l ib can be negatively charged efficiently.

 [0048] With the above configuration, the positive charging blade 11a and the negative charging blade l ib can be charged positively and negatively by one drive unit 14, respectively.

 Accordingly, negative lightning falls on the positively charged wing 11a, and positive lightning falls on the negatively charged wing 11b.

 [0049] In addition to the above-described configuration, for example, a lightning protection device that rectifies an alternating current and divides the current into positive and negative, and has a positively charged portion and a negatively charged portion using the positive and negative. You can configure it.

 Even in this case, the same effects as in the first and second embodiments can be obtained.

[0050] Further, either one of the plus and minus sets may be used. For example, the force S can be configured to include the positive charging unit 2a or the positive charging blade 11a that is positively charged and not the negative charging unit 2b or the negative charging blade ib that is negatively charged. In this case as well, a negative lightning can be dropped on the positive charging unit 2a or the positive charging blade 11 and the lightning can be induced.

[0051] Further, the positively charged layer 23a is not limited to nylon, and may be composed of, for example, a carbon member. In this case, by connecting one of the electrodes of an appropriate power source to the carbon member, the powerful bon member can be negatively charged and negative ions can be generated. Therefore, in this case as well, it is possible to prevent lightning. This carbon member can be produced by carbonizing an appropriate material. Specifically, for example, the carbon member can be produced by carbonization in a high temperature atmosphere filled with water vapor.

 Example 3

 FIG. 6 is a configuration diagram showing a schematic configuration of the lightning arrester 20 of the third embodiment.

 The lightning striker 20 according to the third embodiment includes a positive charging unit 22a on the top thereof.

Yes

 [0053] A conductive plate-like conductor 25 such as a metal plate is provided under the lightning striker 20. An insulator 26 is interposed between the conductor 25 and the positive charging unit 22a in the lightning striker 20.

 As with the positive charging unit 2a of the lightning arrester 1 of the first embodiment, the positive charging unit 22a is provided with an outer wall 23a in the entire housing, and a corona discharge device 24a is provided therein. The lightning striker 20 is equipped with a negative charging unit used for positive lightning.

 [0054] The conductor 25 is installed on the ground A and connected to a ground G (earth) disposed in the ground.

 [0055] Furthermore, on the upper surface of the insulator 26, a concave storage portion 26c for storing the substantially lower half of the positive charging unit 22a is provided.

[0056] Further, the bottom surface of the insulator 26 is provided with a flat force that can be grounded on the top surface of the conductor 25. The recess 26a has a circular shape as viewed from the bottom and is recessed upward from the center of the bottom surface. For this reason, the insulator 26 is thin at the concave portion 26a, and the concave portion 26a and the conductive layer 26 are thin. A space B is formed between the body 25 and the body 25.

[0057] Note that, in the lightning striker 20, a needle 28 may be erected from the upper surface of the positive charging unit 22a as shown by the phantom line in FIG. In this case, the lightning T is guided to the positive charging unit 22a as compared with the case without the needle 28.

[0058] Hereinafter, the operation and effect of the lightning striker 20 described above will be described with reference to Figs.

 FIGS. 7 to 9 are operation explanatory views of the lightning striker 20 schematically showing the lightning striker 20 of the third embodiment. In particular, FIG. 8 is an explanatory diagram showing an enlarged portion corresponding to the region X in FIG. 7 (b).

 First, as shown in the schematic diagram of FIG. 7 (a), when there is a possibility of a lightning strike, the power supply unit 6 described in the first embodiment in the lightning arrester 20 is turned on. Then, the outer wall 23a of the positive charging unit 22a is positively charged (for example, + 200V, + 1000V, etc.) by the discharge of the corona discharge device 24a.

 [0060] By charging the outer wall 23a positively as described above, as shown in the schematic diagram of FIG. 7B, a negative lightning is guided to the outer wall 23a, not the building, and falls.

 [0061] When lightning strikes, the outer wall 23a of the positive charging unit 22a is negatively charged. The potential difference between the outer wall 23a and the ground A becomes very large (tens of thousands of volts to 100 million volts). Therefore, as shown in the schematic diagram of FIG. 8C, the lightning charge on the outer wall 23 a jumps over the thin portion 26 b of the insulator 26 and is discharged to the conductor 25. Then, dielectric breakdown occurs as shown in FIG. 8 (b).

 Thereafter, the lightning charge on the outer wall 23 a is directly discharged from the outer wall 23 a toward the conductor 25 between the positive charging unit 22 a and the conductor 25.

 As described above, lightning charges flow into the conductor 25 as shown in the schematic diagram of FIG. 9 (e). The conductor 25 is connected to a ground G provided in the ground. For this reason, as shown in the schematic diagram of FIG. 9 (f), the conductor 25 can flow lightning charges to the ground G side embedded in the ground A having insulation properties.

In the lightning striker 20 of the third embodiment, an insulator 26 is interposed between the positive charging unit 22a and the conductor 25. For this reason, the positive charge charged in the positive charging unit 22a is efficiently stored without flowing into the conductor 25 or the like. And when lightning strikes, Flowed into ground G due to dielectric breakdown of edge 26.

 In addition, the positive charging unit 22 a is accommodated by the insulator 26. As a result, when the corona discharge device 24a positively charges the outer wall 23a, the charge does not inadvertently flow into the ground. Therefore, power consumption required for charging is not wasted.

 [0066] Note that the portion where the insulator 26 breaks down and lightning charges flow is not limited to the thin portion 26b.

 For example, the recess 26b may be formed on the bottom side of the storage portion 26c of the insulator 26. In addition, a communication hole may be formed in the central portion of the insulator 26 and discharged directly from the outer wall 23a to the conductor 25. Example 4

 As shown in FIG. 10, the lightning striker 30 of the fourth embodiment includes the positive charging unit 22a, the conductor 25, and the insulator 26 (hereinafter referred to as “lightning striker body 20a”). Equipped with a lifting device 32 that lifts against the ground A!

 FIG. 10 is a configuration diagram showing a schematic configuration of the lightning arrester 30 of the fourth embodiment. Specifically, the lifting device 32 supports the lightning device main body 20a from the lower side, protrudes upward with respect to the ground A, or retracts downward, and the rod 33 uses hydraulic pressure. It is provided with a movable device 34 that can be moved.

[0068] The movable device 34 is buried in the ground. This mobile device 34 is mainly a lightning striker body

A pipe 35 embedded in an upright manner at the lower end J of 20a, an oil tank 36, and two narrow pipes 37a and 37b connected between the pipe 35 and the oil tank 36 are provided. The two thin tubes 37a and 37b are connected to the upper and lower sides of the tube 35, respectively. In the middle of the thin tubes 37a, 37b

39a, a direction control valve 39b, and a flow rate control valve 39c are provided.

[0069] In addition, a piston 40 is provided inside the tube 35. The piston 40 slides in the pipe 35 while being connected to one end of the mouth 33 in the axial direction.

[0070] With the configuration described above, the force S can be achieved by moving the rod 33 upward and raising the lightning striker main body 20a with respect to the ground A. Further, the rod 33 is moved downward so that the lightning device main body 2

Oa can descend with respect to ground A.

[0071] For example, as shown in FIG. 11, the lightning striker 30 having the above-described configuration may be provided in a place slightly away from a town where thunderclouds are likely to occur. In particular, when a lightning striker 30 is installed on the windward side of the city, it can be discharged before thunderclouds reach the city, and lightning strikes to the city can be prevented.

 FIG. 11 is an explanatory diagram of the operation of the lightning striker 30 of the fourth embodiment.

[0072] The lightning striker 30 is provided in such a place, and the cloud gradually charges and does not develop into a thundercloud. ¾ When approaching the town, the lightning striker body 20a is raised by the lifting device 32. . As a result, even if the thundercloud is not yet fully developed, the potential difference corresponding to the distance between the thundercloud and the lightning striker main body 20a can be increased, and the positive charging unit 22a can be lightened.

 [0073] Thus, since the potential of thunderclouds can be lowered before reaching the city, lightning does not occur even when reaching the city.

 Of course, the lightning striker 30 of the fourth embodiment may be provided in the city. In this case, when thunderclouds are generated, the potential difference charged to the positive charging unit 22a is reduced to a height at which the potential difference is equal to or higher than the potential difference corresponding to the distance between the top position of the building and the ground surface. The apparatus body 20a may be lifted by the lifting device 32.

 As a result, the positive charging unit 22a can be struck by lightning.

 Example 5

 FIG. 12 is a configuration diagram showing a schematic configuration of the lightning arrester 41 of the fifth embodiment.

 The lightning striker 41 according to the fifth embodiment includes a positive charging unit 42a, the insulator 26, and the conductor 25.

 [0075] On the upper surface of the positive charging unit 42a, a positive charging blade 41a that rotates horizontally is provided.

 As with the positive charging blade 1 la of the second embodiment, the positive charging blade 41 a is provided with a positive charging layer 53 a on the surface thereof. The positively charged layer 53a is made of a material such as nylon that is positively charged when exposed to wind!

[0077] Further, inside the positive charging unit 42a, there is provided a drive unit 44 for rotating the positive charging blade 4la with a driving force instead of the corona discharge device 4a.

With the configuration described above, the lightning strike device 41 of the fifth embodiment can positively charge the positive charging blade 41a in the same manner as the lightning strike device 10 of the second embodiment. For this reason, the lightning arrester of Example 5 41 can drop negative lightning.

Note that the lightning strike device 41 including the positive charging blade 41a described above can also include the lifting device 32 of the fourth embodiment.

 [0080] The lightning arresters 30 and 41 of Embodiments 4 and 5 are not limited to the positively charged configuration as in the above-described configuration, but are configured to be negatively charged or charged with a set of positive and negative. Good.

 Example 6

 [0081] Further, the lightning strike device is not limited to the configuration of the above-described embodiment, and can be configured as in the sixth embodiment. For example, as shown in the configuration diagram of FIG. 13, a lightning striker 1A having a configuration in which the positive charging unit 2a that is positively charged is not provided but the negative charging unit 2b that is negatively charged is provided at the uppermost position of the building K. It can also be set up to avoid lightning. In this case, for example, a negative charging unit 2b can be provided at the highest position to prevent lightning strikes such as ships and buildings, making it difficult for lightning to fall.

 At this time, the negative potential charged to the negative charging unit 2b is preferably set to a potential that cancels the potential difference corresponding to the distance between the uppermost position and the ground surface.

 [0083] Thereby, negative lightning falling from above can be avoided. In other words, the negative charging unit 2b or negative charging blade l ib has a lower potential than the ground potential, which is lower than the ground potential. Lightning strikes on the ground, etc. without lightning on 2b or negatively charged wing l ib. Therefore, it is possible to prevent a lightning strike on the lightning strike object itself.

 [0084] In addition, the lightning arresters 20, 30, and 41 of the above-described embodiments can be reused by replacing the insulator 26 that has undergone dielectric breakdown due to lightning strikes with a new insulator 26 that has not undergone dielectric breakdown. .

 Example 7

 FIG. 14 is a configuration diagram showing a schematic configuration of the lightning arrester 100 of the sixth embodiment.

The lightning strike device 100 of the seventh embodiment includes a lightning radar 102, a DC power supply 103 with a storage function, a ground current control device 104, a booster 105, a potential phase switch 106, a lightning striker 107, and a lightning protection electrode 1 08 Is provided. [0086] A pair of cables is provided between the DC power supply 103 with a storage function and the ground current control device 104, between the ground current control device 104 and the booster 105, and between the booster 105 and the potential phase switch 106. Bull 11 la, connected by 11 lb.

[0087] A positive voltage (plus voltage P) is supplied to the one cable 11 la between the DC power supply 103 with a storage function and the potential phase switch 106, and the other cable 11 lb has Negative voltage (minus voltage M) is supplied.

Furthermore, the one cable 11 la is connected between the potential phase switch 106 and the lightning arrester 107.

 On the other hand, the other cable 11 lb is connected between the potential phase switch 106 and the lightning protection electrode 108.

 The lightning radar 102 detects that a thundercloud has arrived, and also detects whether the electric field strength or the lower part of the thundercloud is charged with a positive or negative charge. The lightning radar 102 is preferably installed on the windward side of the street.

 Further, in the seventh embodiment, the lightning radar 102 employs a mechanism that detects lightning based on a change in the potential difference in the air. The lightning radar 102 can detect lightning without being limited to this configuration. Any other device may be used as long as it is a device.

 [0091] The DC power supply 103 with a power storage function appropriately supplies power to the lightning radar 102, the earth current control device 104, the booster 105, the potential phase switch 106, the lightning arrester 107, and the lightning arrester electrode 108. Functions as a power source. It also has a power storage function that stores the power required to perform high-voltage discharge.

 In the ground current control device 104, the positive side and the negative side are connected to the ground (GND), and current transformers 112a and 112b are provided on the connection lines, respectively. Accordingly, the ground current control device 104 measures the charge on the ground.

 The booster 105 is configured to boost the positive voltage P and the negative voltage M supplied from the ground current control device 104 side so that the absolute value of each voltage becomes a high potential.

[0094] The potential phase switch 106 is a force for supplying a positive voltage P or a negative voltage M to each of the lightning arrester 107 and the lightning arrester electrode 108. The positive / negative combination (phase) of the voltage to be supplied can be appropriately reversed and supplied. it can.

 [0095] For example, when a positive voltage P is supplied to the lightning arrester 107 side, a negative voltage M is supplied to the lightning protection electrode 108, or when a negative voltage M is supplied to the lightning arrester 107 side. The lightning electrode 108 is switched to supply a positive voltage P.

 [0096] The electric charge that the thundercloud is charged indicates the electric charge that is charged in the lower part of the thundercloud (the same applies hereinafter).

 [0097] It is preferable that the lightning arrester 107 is installed in a safe place even if lightning strikes. On the other hand, it is preferable that the lightning protection electrode 108 is appropriately installed on the top of a building where lightning is to be prevented.

 [0098] Furthermore, the lightning arrester 107 and the lightning protection electrode 108 are connected to one end of a lightning protection device 109 such as a well-known SPD for releasing the direct lightning strike to GND when a direct lightning strike occurs. The The other end of the lightning protection device 109 is connected to GND, thereby protecting the potential phase switch 106 and the like from direct lightning strikes.

 [0099] In the following, for example, an operation performed by the lightning striker 100 having the above-described configuration when a negatively charged lightning arrives in the town will be described.

 [0100] Based on the detection signal from the lightning radar 102, a positive voltage P or a negative voltage M is supplied from the earth current controller 104 to each of the two cables 111a and 111b. Each voltage value of the positive voltage P and the negative voltage M is boosted by the booster 105.

 [0101] Furthermore, the potential phase switch 106 supplies the supplied positive voltage P and negative voltage M to the lightning arrester 107 side and the lightning protection electrode 108 side with positive and negative charges. That is, a positive voltage P opposite to the negative charge charged in the thundercloud is supplied to the lightning arrester 107 side. On the other hand, the same negative voltage M as the electric charge of the thundercloud is supplied to the lightning protection electrode 108 side.

 In this way, the lightning strike device 100 can reliably drop lightning on the lightning striker 107 by charging the lightning striker 107 to a potential opposite to the charge charged in the thundercloud. The lightning strike device 100 can flow the charge of the lightning striker 107, which is negatively charged by a lightning strike, to the ground.

On the other hand, the lightning protection electrode 108 is negatively charged the same as the lower part of the thundercloud, thereby Lightning can be reliably prevented by repelling the charge of the minus.

[0103] Next, the operation of the lightning strike device 100 configured as described above when a positively charged lightning arrives in the town will be described.

[0104] In the same manner as when the negatively charged lightning arrives, the earth current control device 10

4. The positive voltage (P) and the negative voltage (M) boosted based on the detection signal of the lightning radar 102 via the booster 105 are supplied to the potential phase switch 106.

[0105] The potential phase switch 106 has two cables 11 la when the thundercloud is positively charged.

The positive voltage (P) and negative voltage (M) supplied from 11 lb are inverted between positive and negative, respectively, and then supplied to the lightning arrester 107 and the lightning protection electrode 108.

Thus, the lightning strike device 100 can supply the negative voltage (M) opposite to the electric charge charged by the thundercloud to the lightning arrester 107 to charge the lightning arrester 107 negatively. Thereby, the lightning striker 100 can reliably strike the lightning striker 107.

On the other hand, the lightning arrester 100 can supply the same positive voltage (P) as the lower part of the thundercloud to the lightning protection electrode 108 to charge the lightning protection electrode 108 positively. As a result, the positive charges repel each other, and the lightning strike device 100 can prevent the lightning strike to the lightning protection electrode 108 with a force S.

 Example 8

 Hereinafter, a schematic configuration of the lightning strike device 110 of the eighth embodiment will be described with reference to FIG.

 However, components similar to those of the lightning strike device 100 described above in the following embodiments are denoted by the same reference numerals and description thereof is omitted.

[0109] In the lightning arrester 110 of the eighth embodiment, the lightning protection electrode 108 is not provided, but the lightning arrester 107 is provided. Between the lightning arrester 107 and the potential phase switch 106, two cables 1

11 a, 11 lb force

[0110] In the case where a negatively charged lightning arrives in the city, the lightning strike device having the above-described configuration

 I will explain the effects of 110!

[0111] As in the case of the seventh embodiment described above, the predetermined voltage boosted based on the detection signal of the lightning radar 102 via the ground current control device 104 and the booster 105 is the potential phase switch 106. To take. [0112] Furthermore, the potential phase switch 106 does not supply the negative voltage M to the lightning arrester 107 side, and only the brass voltage P is supplied to the lightning arrester 107 side with the electric charge supplied from the booster 105. Supply. That is, a positive voltage (P) opposite to the negative charge charged in the thundercloud is supplied to the lightning arrester 107 side. For this reason, the lightning arrester 107 is positively charged.

 [0113] On the other hand, when the thundercloud is positively charged, the potential phase switch 106 does not supply the positive voltage P to the lightning arrester 107 side, but only the negative voltage (M). It is supplied to the lightning arrester 107 side with the electric charge supplied from. That is, a negative voltage (M) opposite to the electric charge charged at the lower part of the thundercloud is supplied to the lightning arrester 107 side. For this reason, the lightning arrester 107 is negatively charged.

 [0114] From the above, even if the thundercloud is charged with a positive or negative charge, the lightning arrester 107 is charged to a potential opposite to that charged with the thundercloud. The lightning striker 107 can surely drop lightning.

 Example 9

 [0115] Hereinafter, a schematic configuration of the lightning protection device 120 according to the ninth embodiment will be described with reference to FIG.

 In the lightning protection device 120 of the ninth embodiment, the lightning arrester 107 is not provided, and a charge dissipator 121 (ionizer) is provided instead. The lightning protection device 120 of Example 9

Like the lightning protection device 120 in FIG.

[0116] The charge dissipator 121 is a device that dissipates charges (ions) generated based on the voltage supplied from the potential phase switch 106 in the air.

[0117] A lightning protection device having the above-described configuration when a negatively charged lightning arrives in the city

I will explain the effect of 120!

[0118] As in the case of the above-described embodiment, the predetermined voltage boosted based on the detection signal of the lightning radar 102 via the ground current control device 104 and the booster 105 is the potential phase switch 106. To be supplied.

Furthermore, the potential phase switch 106 supplies the supplied positive voltage P and negative voltage M to the charge dissipator 121 side and the lightning protection electrode 108 side, respectively, with the positive and negative charges. That is, a positive voltage (P) opposite to the negative charge charged in the thundercloud is supplied to the charge dissipator 121 side. In contrast, the lightning protection electrode 108 side has a belt below the thundercloud. The same negative voltage (M) as the electric charge is supplied.

[0120] As a result, a large amount of positive charges (positive ions) are continuously dissipated from the charge dissipator 121 into the air. As a result, as shown in FIG. 17, a protective shield Z by the positive charge is formed above the charge dissipator 121. With this protective shield Z, it is possible to discharge the electric charge charged to the lightning before it strikes on the ground, and to mitigate the rise of the electric field between the ground and the thundercloud.

 FIG. 17 is an operation explanatory view schematically showing how a large number of positive charges (plus ions) are dissipated from the charge dissipator 121 under the negatively charged thundercloud.

On the other hand, although not shown, the lightning protection electrode 108 is charged with the same negative charge as that of the thundercloud, so that the negative charges repel each other. As a result, lightning strikes to the lightning protection electrode 108 can be reliably prevented.

[0122] Next, the operation of the lightning protection device 120 having the above-described configuration when a positively charged lightning arrives in the town will be described.

[0123] In the same way as when the negatively charged lightning arrives, the earth current control device 10

4. A predetermined voltage boosted based on the detection signal of the lightning radar 102 is supplied to the electric phase switch 106 through the booster 105.

[0124] When the thundercloud is positively charged, the potential phase switch 106 has two cables 11 la, 1

The positive voltage (P) and the negative voltage (M) supplied from 1 lb are respectively reversed in the positive and negative directions and supplied to the charge dissipator 121 and the lightning protection electrode 108.

Thus, a negative voltage (M) is supplied to the charge dissipator 121 side, and the charge dissipator

 From 12, it can dissipate a large amount of negative charges opposite to those charged in thunderclouds. For this reason, lightning can be reliably prevented.

On the other hand, a positive voltage (P) is supplied to the lightning protection electrode 108. By charging the lightning protection electrode 108 to the same plus as that of the lower part of the thundercloud, positive charges repel each other, and lightning can be reliably prevented.

[0127] Also, for example, when a well-known tip discharge phenomenon that generates a charge (ion) opposite to the thundercloud charge is installed on the ground with a pointed metal or the like, weather such as strong wind There was a problem that the charge was shifted depending on the conditions, and as a result, malfunction was likely to occur. This On the other hand, in the ninth embodiment, a voltage is artificially generated by supplying a voltage to the charge dissipator 121 side. Therefore, a large amount of electric charge according to the electric field strength of lightning is dissipated to make sure. It has the advantage that lightning can be prevented.

 Example 10

 [0128] Hereinafter, a schematic configuration of the lightning protection device 130 according to the tenth embodiment will be described with reference to FIG.

 The lightning protection device 130 of Example 10 is not provided with the lightning protection electrode 108, and two cables 11 la and 11 lb are arranged between the potential phase switch 106 and the charge dissipator 121. ing.

 [0129] When a negatively charged lightning arrives in the city, the lightning protection device having the above-described configuration

 I will explain the effects of 130!

[0130] As in the above-described embodiment, the predetermined voltage boosted based on the detection signal of the lightning radar 102 via the ground current control device 104 and the booster 105 is the potential phase switch 106. Supplied.

 [0131] Further, the potential phase switch 106 is a positive voltage that remains the charge supplied from the booster 105.

Supply only P to the charge dissipator 121 side.

[0132] On the other hand, when the thundercloud is positively charged, the potential phase switch 106 supplies only the negative voltage (M) as the supplied charge to the charge dissipator 121 side. Supply

[0133] From the above, even if the thundercloud is charged with either positive or negative charge, a large amount of charge opposite to the charge of the thundercloud is dissipated from the charge dissipator 121. Therefore, the electric field rise between the ground and the thundercloud can be mitigated and discharged before the lightning strikes on the ground, and as a result, lightning can be prevented.

 [0134] Further, the lightning arresters 100 and 110 of the seventh and eighth embodiments and the lightning protection devices of the ninth and tenth embodiments described above.

 120 and 130 may be configured to detect lightning by other means without installing the lightning radar 102 described above. For example, by flowing direct current electricity from the earth current control device 104 to the ground, it is possible to measure the arrival of lightning and the amount of electric charge due to thunderclouds.

[0135] However, it is preferable to provide the lightning radar 102 as in the above-described embodiment because thunderclouds can be detected accurately. [0136] By specifically using the lightning radar 102, for example, a wide range having a radius of 40 km or more can be detected. As a result, it is possible to secure a sufficient storage time required for the DC power supply 103 with a storage function to store the power required to supply the booster 105.

 [0137] Furthermore, when detecting the presence of a thundercloud based on the ground charge, the gravitational force of the charge itself may cause a gap between the thundercloud charge and the ground charge due to weather such as strong winds. Have. On the other hand, when the lightning radar 102 is provided, the electric charge in the air can be detected by the lightning radar 102, so that it is possible to accurately confirm the arrival of lightning.

 [0138] Furthermore, the lightning arresters 100 and 110 of Examples 7 and 8 and the lightning arresters 120 and 130 of Examples 9 and 10 are configured by combining two power sources, The positive / negative voltage balance between 107 and the lightning protection electrode 108 may be changeable. This allows for more detail, control and control.

 Example 11

 [0139] Hereinafter, a schematic configuration of the lightning arrester 50 of the eleventh embodiment will be described with reference to FIG.

 The lightning strike device 50 of the eleventh embodiment includes a traveling vehicle 54 with a lifting arm. This traveling vehicle 54 with a lifting arm is provided with a lifting arm 53 that can be expanded and contracted in the vertical direction and has the same configuration as a general crane vehicle. A lightning device main body 51 is provided at the tip of the lifting arm 53. The lightning arrester main body 51 has the same configuration as that of the lightning arrester main body 31 of the fourth embodiment, i.e., includes the positive charging unit 22a, the conductor 25, and the insulator 26! /

 [0140] Further, the traveling vehicle 54 with the lifting arm is provided with a column 55 for installation. When the lifting arm 53 is raised, the installation column 55 protrudes downward and is installed on the ground A. This installation column 55 can be used to support the traveling vehicle 54 with a lifting arm stably.

[0141] The installation column 55 is configured to be extendable in the vertical direction. The installation column 55 is retracted to the traveling vehicle 54 with the lifting arm during movement. Further, the installation column 55 itself has a conductive member. For this reason, when the installation column 55 is installed on the ground, the conductor 25 of the lightning arrester main body 51 and the ground A acting as the ground are electrically connected. It functions as a connected connection means.

 [0142] With the above-described configuration, for example, when a thundercloud (not shown) appropriately detects that a thundercloud has arrived toward the city, the thundercloud is expected to pass to a place outside the city where it is expected to pass when it arrives. The traveling vehicle 54 with the lifting arm is moved, and the traveling vehicle 54 with the lifting arm is put on standby in preparation for the arrival of thunderclouds (see the phantom line in FIG. 19).

 [0143] Further, the lightning device main body 51 is raised by moving the installation column 55 downward and placing it on the ground, and rotating or extending the lifting arm 53 appropriately.

 [0144] The lightning strike device 50 of Example 1 1 can perform a lightning strike S in the process in which a thundercloud passes through the lightning strike device 50. The operation of prompting lightning strike from the thundercloud by the lightning striker main body 51 is the same as in the above-described embodiment, and will not be described in detail. However, the electric charge charged to the conductor 25 by the lightning strike acts as a ground through the installation column 55. It can be poured into the ground outside the city.

 [0145] As described above, the lightning protection device 50 of the embodiment 1 1 has the lightning protection device body 5 by the lifting arm 53.

Raising 1 will ensure that lightning will strike even if the thundercloud is not yet fully developed before it reaches the city.

[0146] Furthermore, the lightning arrester 50 of Example 11 1 moves not only to a certain place as in the case where the lightning striker main body 51 is installed on the ground, but also to an arbitrary place by the traveling vehicle 54 with a lifting arm. The power S to do.

 For this reason, regardless of which travel route the thundercloud arrives in the city, it is possible to make lightning strikes reliably by making it stand by as described above in any place until it reaches the city. Monkey.

[0147] Furthermore, the lightning strike device 50 according to the embodiment 11 does not get in the way because the lightning device 50 only has to be kept waiting at a predetermined standby place in a weather where there is no possibility of a thundercloud coming.

[0148] As described above, the lightning strike device 50 according to the embodiment 11 is not limited to being used outside the city as described above because it does not get in the way during the weather when there is no possibility of a thundercloud. Use it in the city.

[0149] Further, the lightning strike device 50 of the embodiment 1 1 is not limited to the same configuration as the lightning strike device body 31 of the embodiment 4 as the lightning strike device body 51 of the embodiment 11 and is described above. Lightning device 1 of Example 1 The lightning strike device 20 of the third embodiment and the lightning strike device 41 of the fifth embodiment may have the same structure as that of the lightning strike device 41 of the fifth embodiment.

[0150] Furthermore, the lightning strike device 50 of the eleventh embodiment may be configured such that a lightning radar is mounted on the traveling vehicle 54 with a lifting arm.

 Example 12

 FIG. 20 shows a schematic configuration diagram of the lightning charging apparatus 201 of the twelfth embodiment.

 The lightning charging device 201 includes a lightning striker 202, a transmission line 205, and a plurality of charging units 206.

 The lightning striker 202 is composed of an outer outer wall 203 and an inner corona discharge device 204. The outer wall 203 is composed of a material that easily charges positively!

 The corona discharge device 204 performs corona discharge toward the top plate of the outer wall 203 with electric power supplied from a power supply unit (not shown), and charges the top plate of the outer wall 203 to plus. As a result, the outer wall 203 is positively charged around the top plate portion. The positive charging of the lightning arrester 202 may be charged to an appropriate voltage such as + 200V or + 1000V.

 [0153] This positive charging may be performed when a lightning strike may occur due to a thundercloud or the like. Therefore, the lightning striker 1 may be configured to execute positive charging of the lightning striker 202 when an execution start is input to the input unit such as a push button (not shown).

 [0154] It should be noted that the corona discharge mechanism of the corona discharge device 204 may be a known mechanism. For example, the corona discharge device 204 is provided with an electrode needle composed of a sharp needle. Then, a high voltage is applied to the electrode needle from the power supply unit 6. As a result, the electrode needle emits ions around and discharges corona.

 [0155] The transmission line 205 is composed of an appropriate electric wire. The transmission line 205 is buried in the ground, and its upper end is electrically connected to the outer wall 203 of the lightning arrester 202. The transmission line 205 is branched into a plurality of parts from the middle. A plurality of charging units 206 are arranged in close proximity to each branch portion of the transmission line 205! /.

[0156] The charging unit 206 includes a charging unit 207 and a coin 208. Coinole 208 The linear transmission line 205 is wound around the circumference. Both ends of the coil 208 are connected to the charging unit 207. The charging unit 207 is composed of a rechargeable secondary battery.

[0157] With the above configuration, the lightning charging device 201 can charge the outer wall 203 positively and drop the lightning T on itself as shown in Fig. 21 (A). In detail, thunderclouds are usually negatively charged. At this time, positive charges are gathered on the ground. When the electric field region created between the minus of the thundercloud and the plus on the ground A reaches the limit, it discharges from the thundercloud toward the point where the lightning strikes on the ground A most easily. Here, since the lightning charging device 201 positively charges the outer wall 203, the point where lightning strikes most easily becomes the outer wall 203 of the lightning charging device 201. Accordingly, lightning falls on the outer wall 203 of the lightning charging device 201 which is not on the ground A or other structures.

 [0158] When lightning strikes the outer wall 203, the lightning current flows through the transmission line 205 into the ground in all directions. Here, when current flows in the transmission line 205, an induced electromotive force is generated in the coin 208 of the charging unit 206. The charging unit 207 is charged by the induced electromotive force.

 [0159] The power charged in the charging unit 207 may be transmitted to the substation through an appropriate transmission line (not shown). Also, the charging unit 207 can be replaced, and the charging unit 207 charged by a lightning strike can be replaced with an uncharged charging unit 207! /.

 [0160] In this way, the power generated by lightning can be stored in the charging unit 207 and used separately. In addition, since lightning is guided to the lightning striker 202, it is possible to prevent lightning from reaching other places. Therefore, facilities around the lightning charging device 201 can be protected from lightning. Embodiment 13

 FIG. 22 shows a schematic configuration diagram of a lightning charging system 210 using the lightning charging device 201 of the twelfth embodiment described above.

 The thunder charging system 210 includes a thunder charging device 201 and a thundercloud generator 211. Since the thunder charging device 201 is the same as that described in the twelfth embodiment, a detailed description thereof will be omitted.

[0162] The thundercloud generator 211 is installed on the ground A that is windward than the thunder charger 201. The thundercloud generator 211 is composed of an appropriate heater or the like, and heats air near the ground surface. The thundercloud generator 211 generates water vapor by heating the water with a heater. The thundercloud generator 211 generates water vapor and heats air near the surface of the earth, thereby generating an updraft and generating thundercloud C.

 [0163] The thundercloud generator 211 has a power unit (not shown). The power unit may use appropriate power such as power generated by solar power generation, power supplied from a power plant, or power obtained by the lightning charger 201.

 With the above configuration, thundercloud T can be generated by thundercloud generator 211, lightning T can be dropped on lightning device 202 of lightning charger 201, and power can be acquired by lightning charger 201. By generating thundercloud C by thundercloud generator 21 1, power S can be obtained stably by thunder charger 201. Therefore, it can be used as a power plant.

 [0165] In addition, by installing this lightning charging system 210 on the windward side of the city, it is possible to discharge thundercloud C (lightning strike) in front of the city. For this reason, the clouds carried to the city by the wind are becoming less charged. This prevents lightning strikes such as building K in the city.

 Example 14

 FIG. 23 shows a schematic configuration diagram of a lightning charging apparatus 201a of the fourteenth embodiment.

 The lightning charging device 201a has the same lightning striker 202 and transmission line 205 as in the twelfth embodiment, and also has a switching device 221 and a charging mute 225.

[0167] Switching device 221 switches between supplying lightning current flowing from transmission line 205 to charging unit 225 or flowing to ground. In particular, the lightning current overflowing from charging unit 225 is sent to ground.

[0168] Charging unit 225 is buried in the ground. The charging unit 225 includes a negative charging unit 226, an insulating unit 227, and a positive charging unit 228.

 The negative charging unit 226 accumulates negative charges due to the flow of lightning current. The insulating part 227 is formed in a cylindrical shape by an insulating member. The insulating unit 227 electrically separates the negative charging unit 226 and the positive charging unit 228 from each other.

The positive charging unit 228 is connected to the ground when a negative lightning current flows through the negative charging unit 226. Accumulate positive charges collected from inside. That is, a positive charge is drawn around the huge negative current flowing into the negative charging unit 226. Therefore, the positive charging unit 228 accumulates this positive charge.

 [0169] With the above configuration, it is possible to drop lightning into the lightning striker 202 and charge the charging unit 225 with this lightning current S. Since the charged charging unit 225 has positive and negative electrodes, it can function as a battery. Therefore, the lightning charging device 201a functions as a battery manufacturing device that uses lightning current.

 [0170] According to each of the embodiments described above, it is possible to effectively use lightning and to use lightning power. When power is obtained by lightning, no waste is generated unlike thermal power generation and nuclear power generation, so that the lightning charging devices 201 and 201a can be used as clean energy sources.

 [0171] Note that the charging units 206 and 225 may be configured by other charging units. For example, a primary coil may be connected to the transmission line 205, a secondary coil may be installed in close proximity to the primary coil, and a charging unit may be connected to the secondary coil. In this case, a lightning current flows through the primary coil, and an induced electromotive force is generated in the secondary coil, which can charge the charging unit.

 Example 15

 FIG. 24 is a partial cross-sectional perspective view of the entire wind power generator 301 of Example 15, FIG. 25 is an enlarged cross-sectional view of the rotor blade 302, and FIG. 26 is a partially enlarged view of the wind power generator 301. FIG. 27 is a block diagram of the lightning arrester 309.

 [0173] The wind turbine generator 301 includes a pedestal 307 installed on the ground A, a tower 305 erected at the center position of the pedestal 307 in plan view, and a nacelle 30 provided at the top of the tower 305. 4 and a rotating blade 302 rotatably provided on the front side of the nacelle 304. A lightning arrester 309 is installed at a position slightly away from the wind power generator 301. The lightning protection device 309 and the wind power generation device 301 constitute a wind power generation system.

[0174] Three rotor blades 302 of the wind power generator 301 are provided and connected to each other at the same angle (120 degrees) at the center. These three rotor blades 302 are integrated into the front and rear. The rotating shaft 311 (see Fig. 26) is rotated around the rotating shaft. Each rotary blade 302 is formed to a length of about 40 m. The rotary blade 302 is a force that adjusts the inclination angle of the rotary blade 302 with respect to the wind according to the strength and direction of the wind to an optimum angle. Since this adjustment method is well known, detailed description thereof is omitted.

 As shown in FIG. 25, in this rotor blade 302, an insulating layer 302b made of rubber or the like is provided on the entire outer periphery of a casing 302a made of a hard member such as a metal. A negatively charged layer 302c is provided on the entire outer periphery. The negatively charged layer 302c is made of a member such as a bullet or leather that is negatively charged when exposed to wind. For this reason, while the rotating blade 302 rotates for wind power generation, the negatively charged layer 302c is always negatively charged. In addition, since the insulating layer 302b is provided throughout the inside of the negatively charged layer 302c, it is possible to prevent the charged negative charge from being discharged through the wind power generator 301 and efficiently. Can be negatively charged. This negative charge is preferably performed to the same or lower potential than the Earth as seen from the thundercloud (for example, about 30V to 50V)!

 [0176] The Nasenor 304 shown in Fig. 24 has a rotating blade 302 connected to the front and a top of the tower 305 connected to the lower side. Inside the nacelle 304, as shown in FIG. 26, a double speed machine 312 for increasing the rotational speed, a brake device 313 for suppressing the rotational speed as necessary, a generator 314 for converting rotational power into electric power, and a voltage A generator transformer 315 for transforming the power to a predetermined voltage is arranged in this order from the front rotor blade 302. The nacelle 5 rotates in the horizontal direction with the vertical direction as the axis of rotation in order to efficiently rotate the rotor 302 by the wind received, and the force S that optimizes the orientation of the rotor 302 relative to the direction of the wind S The detailed operation is well known and will be omitted.

 [0177] Tower 305 is a vertical tower extending upward from the installation part, and is formed with a length of about 60 m. The lower end serving as the base of the tower 305 is firmly fixed to the pedestal 307. This prevents the tower 305 from collapsing due to strong winds.

[0178] In addition, an electrical cable 318 is arranged in the vertical direction inside the tower 305. The upper end of the electric cable 318 is connected to the generator transformer 315 in the nacelle 304, and the lower end is connected to the tower side charging unit 321! /. [0179] The tower-side charging unit 321 has an electrical cable 318 connected at the front stage, an electric cape 322 at the rear stage, and a tower-side connection contact 323 at the rear stage of the electric cable 322. The tower-side charging unit 321 passes through the electric power flowing through the electric cable 318 as it is without being normally used by switching the internal switch. When the connection between the tower side connection contact 323 and the external side connection contact 325 is released and the switch is turned off in a situation where there is a risk of lightning, the tower side charging unit 321 is charged by the electric power sent from the generator 314. And accumulate power.

 [0180] The pedestal portion 307 is a substantially circular pedestal in plan view that supports the tower 305, and is formed of an insulating member that does not conduct electricity. For example, a hard rubber member can be used as the insulating member. On the bottom surface of the pedestal 307, a rod-like foundation pile 308 that is long in the vertical direction is fixed. By this foundation pile 308, the pedestal 307 is fixed to the ground A, and as a result, the tower 305 is fixed to the ground A.

 [0181] A transformer 331 is provided around the pedestal 307.

 The transformer 331 is provided with a transformer 333 and an external charging unit 335 inside. The transformer 331 includes a straight bar-shaped connection arm 326 and a rotation drive unit 327 that rotates the connection arm 326 by about 90 degrees. An external connection contact 325 is provided at the tip of the connection arm 326.

 As shown in FIG. 27, the lightning arrester 309 is provided with a corona discharge device 392 in the outer wall 391. The corona discharge device 392 discharges corona toward the top plate of the outer wall 391, and charges the top plate of the outer wall 391 positively. As a result, the outer wall 391 is positively charged, and in particular, the top plate portion is positively charged. The positive charging of the lightning arrester 309 may be performed when a lightning strike may occur due to the formation of a thundercloud when charged to about +200 V. Therefore, an input unit such as a push button may be provided, and a positive charge may be executed when an execution start input is received by the input unit.

In the wind power generator 301 configured as described above, during normal power generation, the rotating blade 302 rotates by receiving natural wind, and the rotating shaft 311 also rotates with this rotation. This rotational force is transmitted to the double speed machine 312 and the double speed machine 312 increases the rotational speed. The brake device 313 brakes the rotational force of the double speed machine 312 as necessary. Generator 314 is illustrated The rotating power is converted into electrical energy by a motor that is omitted, and the converted power is sent to the generator transformer 315. The generator transformer 315 transforms the received power to an appropriate voltage and sends it to the transformer 331 via the electric cable 318.

 Here, a tower-side connection contact 323 is connected to the tip of the electric cable 318. Electric power is supplied to the transformer 331 through the connection arm 326 from the external connection contact 325 in contact with the tower side connection contact 323.

 [0185] The transformer 331 transforms the received power to a predetermined voltage by the transformer 333 and transmits the electric power through the electric wire 340. In addition, the external charging unit 335 charges the received power in a time zone or the like where the power is used too much at the power transmission destination and V is low.

 [0186] In a situation where there is a risk of lightning, the transformer 331 causes the rotary drive unit 327 to rotate the connection arm 326 to the standing position as shown in Fig. 26, and the tower side connection contact 323 is connected to the external side. Contact 325 is not contacted and separated to a sufficient distance. When viewed from above, this separation distance is approximately equal to or greater than the distance L from the outer periphery of the tower 305 to the ground A by the pedestal 307. At this time, the wind power generator 301 is in an electrically isolated state.

 In this embodiment, the force that rotates the connection arm 326 up and down The connection arm 326 is rotated to the left and right, or the connection arm 326 is configured to be stretchable. The side connection contact 325 may be separated.

 Further, the operation of opening the connection arm 326 by the rotation driving unit 327 may be executed by an attendant inputting to an appropriate input device (for example, a push button).

 [0188] By separating the tower-side connection contact 323 and the external-side connection contact 325 in this way, the wind power generator 301 is electrically separated from the ground A by the base portion 307 formed of an insulating member. It becomes a state.

 [0189] Further, during the electrical separation from the ground A in this way, the power generated by the generator 314 by the rotation of the rotary blade 302 is accumulated by the tower-side charging unit 321. As a result, even during lightning protection, power can be generated and used effectively.

[0190] With the above configuration and operation, it is possible to provide the wind power generator 301 capable of preventing lightning strikes with the force S. More specifically, FIG. 28 is an explanatory diagram for explaining lightning strike prevention by the function of the pedestal part 307. The wind power generator 301 has no part in contact with the ground A by the pedestal part 307 and can be electrically viewed. It will float from the ground A. For this reason, the lightning T falls to another place where the wind power generator 301 cannot fall. In other words, even if the lightning T falls on the wind turbine generator 301, there is no exit for the charge of the lightning T to flow to the earth. In particular, the tower-side connection contact 323 and the external-side connection contact 325 are sufficiently separated from each other, and the base periphery of the tower 305 is also sufficiently separated from the ground A by the pedestal 307. It is also difficult to discharge. For this reason, since there is no exit when the lightning T falls on the wind power generator 301, it does not fall on the wind power generator 301 and falls to another place (for example, the ground A or a tree).

 [0191] FIG. 29 is an explanatory diagram for explaining lightning protection by negative charging of the rotor blade 302 and positive charging of the lightning arrester 309. From a thundercloud charged from about tens of thousands of volts to 100 million volts, Since the rotary blade 302 is charged to minus 30 Bonoleto to minus 50 Bonoleto, there is almost no potential difference from the ground A of 0 Bonoreto. For this reason, it is possible to prevent the lightning T from being struck to the wind power generator 301 where it does not fall on the rotor blades 302. Furthermore, since the lightning arrester 309 is charged to about plus 200 volts, there is a potential difference from the ground A as seen from the thundercloud, and the lightning T tends to fall on the lightning arrester 309. Therefore, it is possible to prevent lightning from being generated on the wind power generator 301.

 [0192] In this way, in order to prevent lightning strikes, the reliability of lightning strike prevention can be improved by making the wind power generator 301 itself not lightning, unlike relying solely on lightning rods.

[0193] In addition, the wind power generator 301 stores the power generated by the generator 314 during lightning strike prevention in the tower-side charging unit 321 so that the power obtained during lightning strike prevention can be effectively used later. .

[0194] Further, since the electric power generated by the wind power generator 301 that is not used at the transmission destination is stored in the external charging unit 335, the electric power from the wind power generator 301 to the transformer 331 during lightning strike prevention Even if the supply is interrupted, the power S can be transmitted from the external charging unit 335 to the transmission destination. [0195] The negative charging means is configured such that the outer periphery of the rotary blade 302 is covered with the negative charge layer 302c. However, the negative surface is negatively charged by other methods, such as charging the surface of the rotary blade 302 to negative by corona discharge or the like. May be charged.

 [0196] Further, the negatively charged layer 302c is not limited to a member such as a bull or leather, but may be formed of, for example, a carbon member. In this case, by connecting one of the electrodes of an appropriate power source to the carbon member, the carbon member can be negatively charged and negative ions can be generated. Accordingly, in this case as well, lightning can be prevented. This carbon member can be manufactured by carbonizing an appropriate material. Specifically, for example, the carbon member can be produced by carbonization in a high temperature atmosphere filled with water vapor.
