Description

The invention relates to the field of high voltage technology, in particular to a circuit breaker in electrical distribution networks. It is repelled by the electrical switching device and the layout of the switching device according to the restrictive part of the independent claims.

In developing the invention, they proceeded from the prior art according to DE 2427451, which discloses a gas-insulated hybrid switching apparatus with outdoor bushings that can be rotated for transport purposes. The bushings can be mounted on the casing of the circuit breaker on the side flanges (horizontally) or above (vertically) for current leads. Additionally, a current lead may be provided on the end side. At this power switch, both current leads on the casing are located in a common plane passing through the shaft of the switching device. If necessary, disconnectors may be provided in the switch housing.

DE 2929054 A1 discloses a multi-chamber circuit breaker having current leads on the front side for a vertically laid-out bushing insulator of an external input installation and on a horizontally allocated conductive busbar isolated from gas. Linear dividers are attached to the taps using flanges through intermediate structural elements.

DE 10013232 A1 shows two multiphase sealed circuit breakers arranged horizontally and provided on the sides with flanges for current leads located on top of the tank, and the current leads, respectively, their middle axes, in this case are located in a common vertical longitudinal plane passing through the shaft of the switching device, and laid vertically up. On the current supply side of the GIS (gas-insulated switchgear), a 90-degree angular structural element with disconnection - grounding functions is installed. By means of a rectangular disconnector, the current lead is deflected to a horizontal position and, due to this, can be connected to a horizontally located GIS busbar.

DE 10011888 A1 for a three-phase high-voltage switchgear shows an H-connection of five groups, respectively, of three parallel circuit breakers. The circuit breakers are horizontal and have current leads or flanges vertically upward for current leads, which are tucked up from the outside and, from the GIS side, are deflected to a horizontal position through an angular disconnector. The power switches on the GIS side can also be equipped with an end current lead, and all the installation nodes on the GIS side are located in a common horizontal plane.

DE 10032656 A1 shows a horizontally positioned “Dead Tank Breaker” with two connecting pipes on the side of the casing. Connecting branch pipes are located in the vertical longitudinal plane passing through a shaft of the switching device, and the plane of their flanges passes horizontally. Two outdoor bushing insulators are installed through the arch-shaped support part on the mounting flange so that the bushings are laid up in a vertical longitudinal plane and extend away from each other in a V-shape. Connecting nozzles can also be located horizontally, so that the plane of their flanges extends vertically. In this case, the first connection pipe is connected to a gas insulated switchgear (GIS), and the second connection pipe is through an outdoor bushing with an air line or transformer. The bushing of the outdoor installation, with the help of an arch-shaped supporting part, is brought out of a horizontal position and laid obliquely upward in a plane (perpendicular to the shaft of the switching apparatus) (transverse plane).

EP 0 744 758 A2 describes a circuit breaker with current leads for cable outlets directed from the casing with a small dilution upwards. Cable taps have disconnectors for taps. Two current leads belonging to the same phase, or their middle axes, are located on the circuit breaker housing, respectively, in a common plane passing through the shaft of the switching device (longitudinal plane). A three-phase switching device is implemented using three power switches located alongside each other, in which the sealing is carried out in phases or in three phases. In both cases, the planes of current leads or cable branches for external phases are tilted outward around the shafts of switching devices by 45 ° from the vertically oriented plane of current leads of the middle phase.

DE 10325681 B3 provides a gas-insulated hybrid switching apparatus in which the longitudinal axis of the circuit-breaker is located at a 45 ° angle from horizontal and vertical. The first flange for current supply is on the front side, the second and third flanges for current supply are located on the side of the casing of the circuit breaker. All current leads, respectively, their middle axes, are located in one vertical plane passing through the shaft of the switching device (longitudinal plane). In this case, the second current supply from the casing side through the cranked flange or through the cranked connecting element is led upward, and the third current supply from the casing side is radially allocated relative to the longitudinal axis of the power switch. Due to this, outdoor bushing insulators on current leads can be branched up with branching. Outdoor bushing insulators have line disconnectors.

DE 10325684 A1 presents a similar gas-insulated hybrid switching apparatus, in which in this case the longitudinal axis of the switch is tilted upwards and there are first current-side flanges and second side conductors for outdoor insulators.

EP 1249910 A1 shows a horizontally positioned, three-phase or single-phase, sealed high voltage circuit breaker, which has two upstream side conductors for a GIS double busbar and two end conductors for cable, overhead lines or transformers.

EP 0 735 637 B1 discloses a horizontally, three-phase or single-phase sealed circuit breaker with an integrated three-position disconnector. Both disconnector taps are withdrawn from the casing side upwards in one plane perpendicular to the longitudinal axis of the switch (transverse plane) V-shaped. Other components, as well as a tap disconnector, are located in the circuit breaker housing.

In the aforementioned circuit breakers with gas-insulated enclosures (Dead Tank Breaker, atmospheric GIS-hybrid switching device, GIS-switch), the outdoor bushing insulators are mainly laid up. In the aforementioned prior art, this happens either directly through the current leads located at the top, mainly directed vertically upwards, or indirectly through the end horizontal or horizontal from the casing side of the current leads, which, with the help of deflecting structural elements from the horizontal position, are deflected upward by 90 ° or, if necessary, by 45 °.

EP 1569254 published a sealed combination disconnector with a selective separation and / or grounding function.

An object of the present invention is to provide a switching apparatus having gas insulation and arranging a circuit breaker with such a switching apparatus that is compact in size and simple in construction and can be easily adapted to various switching systems. According to the invention, this problem is solved by the features of the independent claims.

The invention relates to an electrical switching device for an electric power supply network, in particular a high voltage switch containing a power switch, which is located in a housing extending along a longitudinal axis, the housing having at least one current supply side on its side surface, which serves to connect the tap and has a middle axis, which in the working position of the switching device has horizontal directional components, i.e. not vertical, and between the current supply from the side and the outlet there is a sealed angular disconnector, the input axis of which from the current supply side is parallel to the middle axis, and the output axis from the outlet side is parallel to the longitudinal axis of the outlet, and the input axis and the output axis determine the plane of the disconnector and between the axis of the input and the output axis encloses the angle of the disconnector α, due to which the current supply in the operating position of the switching device is rejected into the plane of the disconnector. The current supply can be implemented using a fitting on the housing and mainly in the form of a flange on the housing. As a disconnector, any switching device can be used here, with the help of which branch removal and / or grounding can be carried out. Thus, using the invention, an outlet is created on the sealed circuit breaker through a non-vertical outlet on the side of the housing casing, which is extremely space-saving and capable of separation and / or grounding.

The advantage of the implementation according to paragraph 2 of the claims is that it is possible to abandon the sealed intermediate structural element used so far, for example, as deflecting ball elements, angular elements or the like, and the function of disconnecting and / or grounding can be implemented on challenge.

The advantage of the implementation according to paragraphs 3-5 of the claims is that with the help of an angular disconnector, at the same time, the preferred tap angle for outdoor bushing and cable taps can be realized.

Preferably, according to paragraphs 6-8, by coordinating the separation angle and the angle of position for each current supply position on the side, the longitudinal axis of the outlet with sufficient steepness is diverted from the horizontal with the bushings of the outdoor installation up and with cable taps down.

Preferably, according to claim 9, an additional degree of freedom is created with the help of the angle of rotation β, due to which an outdoor bushing with greater flexibility to overhead lines and the like can be connected to the branch on the side of the power switch housing. or cable tap in any direction of tap.

Paragraphs 10-13 of the claims relate to the preferred embodiment with several through-flanges connected to a power switch of outdoor bushings or cable outlets.

Particularly favorable in terms of cost according to paragraphs 16-18 of the claims is the installation of a standard combined isolator with the separation and / or grounding function in the form of an angular disconnector, as an option in the form of T, on an air or cable outlet.

The subject of the invention is also the layout of the circuit breaker, in particular the 11/2 layout of the circuit breaker, with a switching device, as described above.

In the drawings, for the same elements, the same position symbols are used and, if necessary, the position symbols for repeating elements are omitted.

1a, 1b, a first embodiment of a switching apparatus 1 is simplified, which comprises a circuit breaker 2 in a housing 3 extending along a central axis 1a, x of the housing 3. At least one current supply 3b is provided on the side surface 2a of the housing 3, which is used to connect an outdoor bushing insulator 4, 40. An open outlet 4, 40 typically leads to an overhead line or transformer. In general, instead of an open outlet 4, 40, there can always be a cable outlet 4, 42 (Fig. 2c).

The current lead 3b has a middle axis H1, which is discharged from the power switch 2, which in the operating position of the switching apparatus 1 has a horizontal (lying in the x, y plane) spatial component. In addition, there is a sealed corner disconnector 7, the input axis T1 of which from the current supply side is parallel to the middle axis H1, and the output axis T2 from the bushing side is parallel to the longitudinal axis B of the outdoor bushing 4. Angle disconnector 7 here can be any angular structural element with the function of separation and / or grounding (angular combined disconnection). The separation plane T12 is defined by the input axis T1 and the output axis T2, and a separation angle α is enclosed between the input axis T1 and the output axis T2. According to the invention, the angle separator 7 is so located between the current lead 3b on the side and the outlet 4 so that the current lead 3b in the operating position of the switching apparatus 1 is deflected into the plane T12 of the disconnector. Thus, with the help of an angular disconnector, a wide angular spectrum is created for laying the bends 4 outward or into cables. The following are examples of implementation.

Further on figa, 1b presents: a high voltage terminal at the end of the bushing of the outdoor installation 4; on the left side of the end, a connecting flange 5a for connecting the drive of the circuit breaker 5 for the power switch 2 not shown here in more detail; on the right, the connecting flange 6 from the side of the end with a valve 6 to relieve pressure. A drive 70 for a disconnector / earthing switch is mounted on the corner disconnector 7. Further, the switching device 1 may have additional structural elements of the housing, for example, a current transformer 8 or a voltage transformer not shown, deflecting structural elements, structural connection elements, structural elements of a disconnector and / or ground electrode, or the like.

The switching apparatus 1 is mounted on a supporting base 9, a concrete base or the like. Switching device 1 can be presented in the form of “Dead Tank Breaker” 1, AIS / GIS - a hybrid switching device 1, or a GIS-switching device with an air or cable outlet. The switching apparatus 1 may comprise any circuit breaker 2, for example, a high voltage circuit breaker 1, or in case of a circuit breaker for high rated currents or the like. As a rule, it is not necessary that the longitudinal axis 1a, x of the housing 3 is horizontal. The cross-sectional profile of the housing 3 can be formed completely or partially round, oval, rectangular or polygonal.

Advantageously, the corner disconnector 7 for the proposed lateral connection using the flanges of the outlet 4 is mounted without the use of intermediate structural elements from the input side to the current lead 3b and from the output side to the lead 4. Due to this, without the use of intermediate structural elements, a tight connection is created between the current lead 3b and the outlet 4.

Advantageously, the current supply 3b, 3c, 3d using the separation angle α is deviated from the vertical in the separation plane T12. In particular, the orientation of the longitudinal axis B of the outdoor bushing of the outdoor installation to the sky or for the cable outlet 4, 42 to the ground, and possibly also to the sky, is necessary for the air outlet 4, 40. In a multi-storey installation, it is also possible that a downward bend is created by deflecting to the vertical for the bushing of the outdoor installation.

In another embodiment, the middle axis HI forms a vertical position angle γ with the vertical position angle (γ) lying in the range 30 ° <γ <150 °, preferably 60 ° <γ <120 °, and particularly preferably 80 ° <γ <100 ° and in particular, is γ = 90 °. Further, the separation angle α may lie in the range of 30 ° <α <150 °, preferably 60 ° <α <120 °, and particularly preferably 80 ° <α <100 °, and in particular be α = 90 °. In particular, the angle of separation α and the angle γ of the position are so coordinated with each other that the branch 4 is directed to the vertical up or down at an angle of maximum 60 °, preferably maximum 45 °, particularly preferably maximum 30 °.

Preferably, if in the case of a branch with an outdoor bushing insulator 4, 40 (numerical), the sum of the separation angle α and the position angle γ is selected in the range 130 ° <α + γ <230 °, preferably 140 ° <α + γ <220 °, especially preferably 150 ° <α + γ <210 ° and, in particular, equal to α + γ = 180 °. Due to this, a preferred orientation of the longitudinal axis B of the outdoor bushing insulator in the area towards the sky up and at the same time towards the ground is achieved and good accessibility in the switching area without the risk of high voltage for service personnel.

Further, in the case of cable outlet 4, 42, the sum of the separation angle α and the position angle γ should lie in the region of −50 ° <α-γ <50 °, preferably 40 ° <α-γ <40 °, particularly preferably −30 ° <α -γ <30 ° and, in particular, be α-γ = 0 ° in order to lead the cable 43 (FIG. 2c) down to the ground.

Additionally, the angle switch 7 can be fixedly mounted on the current lead 3b in the rotated position, and the angle β of rotation between the vertical side planes can be set using the input axis T1 and the separation plane T12. Thus, the bushing of the outdoor unit 4, 40 is directed away in the overturned plane of separation with a deviation by an angle β of rotation from the vertical. In particular, the rotation angle β may lie in the range 0 ° <| β | <70 °, preferably 0 ° <| β | <50 °, particularly preferably 0 ° <| β | <30 °. The rotation angle β can be determined by the circumference of the centers of the holes on the mounting flange to the current lead 3b and the input flange of the disconnector. In the case of cable entry 4, 42, the angle of rotation should lie in the region of 110 ° <| β | <180 °, preferably 130 ° <| β | <180 °, particularly preferably 150 ° <| β | <180 °.

Preferably and, as shown in the figures, the middle axis H1 or H2 lies horizontally and the separation angle α lies in the region 80 ° <α <100 ° and is, in particular, α = 90 °. Due to this, branch 4, namely, the bushing of the outdoor installation 4, 40; B, C, D or cable outlet 4, 42, C can be directed up (-70 ° <β <70 °) or down (110 ° <| β | <180 °) in the separation plane T12, and tipping can be added the rotation angle β and, in particular, the branch 4 can be directed vertically upward (β = 0 °) or vertically downward (β = ± 180 °).

On figa, 1b additionally on the side there is a vertical connection 3A for another bushing outdoor insulator 4 with a longitudinal axis A or for an additional device. Alternatively or additionally, at least one end connection for end-to-end outdoor insulators or additional apparatuses may also be provided. As, for example, shown in Fig. C, also between the corner disconnector 7 and the outlet 4, 42 may be a quick-acting grounding switch 71.

Advantageously, as shown in FIGS. 2a, 2b, 2c, 3, 4a, 4b and FIGS. 5a, 5b, 6, there are several non-vertical current leads 3b, 3c on the side, which, respectively, are connected directly through the corner disconnector 7 to the bushing insulators of the outer installations 4, 40 extending along the longitudinal axes B, C, D or cable taps 42. The current leads 3b, 3c, 3d can be offset to each other along the longitudinal axis 1a, x and / or are located relative to a vertical plane passing through the housing 3 switching devices 1 on lying against each other's sides and, in particular, lie against each other (Figs. 3, 4a, 4b, 5a, 5b, 6). For these, from the side, on the side, connected to current leads 3a, 3c, 3d of taps 4; 40, 42; B, C, D likewise indeed the above. In particular, the angle β of rotation for inputs 4; B, C, D can be selected different and preferably diverging, for example, β = 0 ° and β <45 ° (Fig. 2a, 2b) or, respectively, for example | β | <45 ° with the opposite direction of rotation, respectively, is familiar (Fig. .4a, 4b or also figa, 5b, 6, 7).

As the top view in FIG. 2b and FIG. 4b shows, the phases of the switching apparatus 1 can be sealed and three phases of this kind of switching apparatus 1 can be located next to each other. In this case, the corner disconnectors 7 are predominantly driven by the common drive mechanism of the drive disconnectors 10 to control the disconnectors from the common drive of the disconnectors 70. This known common drive 10, 70 of the disconnectors can be implemented in this way in the invention, i.e. . for proposed in accordance with the invention connected by means of flanges on the side and in the case of overturned corner disconnectors 7 for bushing insulators outdoor installation 4, 40; B, C, D and for cable taps 4, 42; FROM.

The subject of the invention is also the arrangement of the switch 1b with at least one electric switching apparatus 1 according to claim 1. Moreover, according to the invention, at least on one switching device 1 between the current leads 3b, 3c, 3d and the outlet 4; 40, 42 a sealed angular disconnector 7 is installed, the input axis T1 of which from the current connection side is parallel to the middle axis H1, H2, and the output axis from the branch T2 lies parallel to the longitudinal axis B, C, D of branch 4; 40, 42, moreover, the separation plane T12 passing through the input axis T1 and the output axis T2 is determined, and a separation angle α is enclosed between the input axis T1 and the output axis T2, to which the current lead 3b, 3c, 3d in separation plane T12.

The layout of the switch 1b can be made in the form of a single busbar system (see switching device 1 according to Fig.1-3), a double busbar system (see switching device 1 according to Fig.4), 11/2 layout of the switch 1b (Fig. .5-7), an H-circuit or the like.

Preferably, as shown in FIGS. 5a, 5b, 6, there is an angular disconnector 7 with which two power circuit breakers 2 are connected to each other on the side. Through the angular disconnector 7 according to the invention, by means of flanges, an outlet 4, 40, 42 is connected at an angle. Moreover, the angular disconnector 7 has a T-shape and along the input axis T1 the first disconnecting hole 12 opposite the third disconnecting hole 14, as well as along the T2 axis the output of the second disconnecting hole 13. The first and third disconnecting holes 12, 14 are used to connect both power switches. The second disconnecting hole 13 serves for separable outlet 4.

For example, in the 11/2 layout of the switch 1b, three switching devices are arranged horizontally and parallel to each other and are connected to each other using an angular disconnector 7.

According to figa, 5b, the middle switching device 1 can be connected by two horizontal laterally displaced current leads 3b, 3d with the help of corner disconnectors 7 with two other switching devices 1, and the corner disconnectors have a rectangular T-shape and along their axis T1, the inputs are connected to other switching devices 1, and along their axis T2 the outputs are connected respectively to branch 4; 40, 42, in particular an outdoor bushing 4, 40 up or with a cable outlet 4, 42 down. At least one of the corner disconnectors 7 can be directly and without using intermediate structural elements along its input axis T1 connected to other switching devices 1 and along its output axis T2 with outlet 4; 40, 42. According to FIG. 6, at least one of the corner disconnectors on both sides can be connected along with its input axis T1 through one of the other disconnectors 7 to other switching devices 1.

According to Fig. 7, the middle switching device 1 is connected on the side by two vertical current leads 3a axially offset to each other by means of corner disconnectors 7 with two other switching devices 1, and the corner disconnectors 7 again having a rectangular T-shape and along the axis Input T2 using one of the other corner disconnectors 7 are connected to other switching devices 1, and along the output axis T2 are connected respectively to branch 4; 40, 42 up or down.

According to a preferred embodiment, the angle switch 7 is represented by a standard combination switch 7, representing the concept for a gas-insulated switchgear. On Fig, as a preferred example, shows a combination disconnector 7, which is the subject of the specified EP 1569254 A1, the General device of which is given by reference in the description. In the housing 11 of the disconnector there is a first and, if necessary, a second hole 12, 13 of the disconnector along the axis T1 of the input, a third hole 14 of the disconnector along the axis T2 of the output, and the axis T1, T2 of the input and output can change their functions; current conductors 15, 16, 17 along the axes T1 or T2 of the disconnector, a mobile, two-piece contact node element 18, which includes a contact part 20 of the disconnector and / or contact part 19 of the ground electrode; a conductive tube 21 for accommodating the movable member 18 of the contact assembly; a holder 22 for detachably securing the contact part 20 of the disconnector and / or the contact part 19 of the ground electrode, which are here made in the form of contact pipes 20, 19, the holder 22 being able to linearly move using the actuator 23, 70 of the disconnector. In particular, the drive shaft of the disconnector 23, the spindle 26, the spindle nut 27, the spindle portions 28, 29 and 30, the slider 31 and at least the guide 32 are represented. Instead of a spindle drive, a linear traction drive, a combination of or another drive of the combination disconnector. The disconnector contact 25 serves when the disconnector T is closed, to receive the contact part 20 of the disconnector. The grounding contact 24 serves when the grounding path E is closed to receive the contacting part 19 of the grounding. A particular advantage of this combined disconnector 7 is that by simply installing the contact part 20 of the disconnector and / or the contact part 19 of the earthing switch, the functions of the disconnector and / or earthing switch can be realized. By dismantling and / or remounting one of the contact part 19, 20, it is very easy to carry out additional readjustment between the disconnection, grounding functions or the combined function. Another great advantage is that the combination disconnector according to FIG. 8 or EP 1569254 can be used in a T-shape with three openings 12, 13, 14 of the disconnector or in L-form with only two openings 12, 13 or 14, 13 of the disconnector moreover, in the third or first hole 14 or 12 of the disconnector to be locked, the conductor 17 or 15 of the disconnector is replaced by a cap (not shown). If necessary, an additional apparatus or the like could be installed there using flanges. An even greater advantage is that all the disconnectors 7 of the switching apparatus 1 (FIGS. 1-4) and the layout 1b of the switch (FIGS. 5-7) can be selected in the form of corner disconnectors 7 according to FIG.
