Description

The invention relates to high-voltage impulse technology and can be used, for example, in high-voltage impulse voltage and current generators.

Multi-gap controlled discharge lamps are known that contain a series of spark gaps, a high-resistance resistor divider for evenly distributing the operating voltage across the spark gaps, a chain of series-connected capacitors directly connected to the extreme electrodes through resistors or inductance. on all other electrodes of the discharge, and the generator set fire to 1}.

The disadvantage of this TPA dischargers is that they can switch a voltage of at least 50% of the static breakdown voltage.

Closest to the present invention, there is a multi-gap controlled discharge gap containing successively arranged electrodes forming a series of successively impacted spark gap shunted by resistors and connected alternatingly to the E and the 4 terminals of the ignition generators using coupling capacitors. .

The disadvantage of this discharge is that the coupling capacitors are not provided with a discharge circuit, which, after the discharge of the discharge, would conduct the potential on the electrodes to one fixed initial state. For this reason, after the triggering of the discharge unit, the coupling capacitors can be charged to different voltages, which reduces the stability of the simultaneous PJig of all spark gaps and limits the frequency of triggering of the bit.

In addition, when the gating unit is operating, the total operating voltage of the storage capacitor is applied to the coupling capacitors. In some cases, when the potential on the capacitors of the communication is floating, the voltage on them may exceed the nominal value and lead to the output of the capacitors.

The purpose of the invention is to increase the stability and frequency of the trigger.

The goal is achieved by the fact that in a multi-gap controlled discharge circuit containing successively located electrodes, forming a series of successively connected spark gap shunted resistors and connected, alternately, to opposite power outputs of the ignition generator using coupling capacitors, one of the outer electrodes is connected to

Ignition generator terminals through additionally inserted resistors.

FIG. 1 shows a schematic electrical diagram of a multi-gap controlled discharge bit,

FIG. 2 is an electrical circuit of connecting groups of three in parallel in the key of other arresters.

Multi-gap controlled discharge (Fig. 1 / contains electrodes

1-7, forming serially connected spark gaps 8-13, ionized by resistors 14-19, coupling capacitors 20-26, conductors 27 and 28, additional

resistors 29 and 30, discharge circuit 31 with storage capacitor 32 and load 33, pins 34 and 35 and ignition generator 36.

Additional resistors 29 and

30 at one end connected to one

From the output times of the DNA in FIG. one

with conclusion 35), and others with conductors 27 and 28, respectively. These same conductors are connected capacitors 20-26, which

the other ends are connected to the corresponding 1m electrodes.

Multichannel glitch works in the following way.

In the initial state, the storage capacitor is charged and at the terminals 34 and 35 of the discharge there is a constant voltage, which by means of shunt resistors 1819 of the voltage divider uniformly fjo is distributed by spark 4 intervals 8-13.

 The length of the spark gap is chosen so that each of them can withstand the applied to

its voltage is equal to the charge voltage across the capacitor 32 divided by the number of spark gaps.

The discharge cycle begins with the supply of a trigger pulse from the ignition generator 36 to the electrodes 1-7 through the coupling capacitors 20-26. In this case, almost simultaneously all the spark gaps and the storage capacitor 32

discharged to load 33.

Due to the presence of additional resistors 29 and 30, all the coupling capacitors are discharged through these resistors and shunt resistors of the voltage divider, i.e. the potentials at the electrodes are reverted to their original value. This is especially important for the operation of a glitter with a high pulse frequency.

Due to the presence of these resistors 29 and 30 connecting the conductors 27 and 28 to one of the arresters, for example, a terminal 35 connected to the electrode 7, when charging the storage condensate: 32, regardless of the internal resistance of the ignition generator, the potential on the conductors 27 and 28 consequently, the electrodes will not float, but will have a fixed value, thus avoiding accidental operations, and eliminate the cause of the operation failures. In this case, the voltage across the coupling capacitors will not be more significant than on the storage capacitor 32. This increases the stability of the operation of all spark gaps.

.Multiple identical dischargers are easily incorporated into. a parallel circuit in parallel (Fig. 2), which will allow increasing the current carrying capacity and reducing the over-capacitance or reducing the current density on the electrodes ..

Parallel connection of several discharge switches is achieved (fig. By direct connection of their extreme electrodes 1–7 and connection of the remaining electrodes 2–6 via the same resistor 37 and Sv and the instigator of the same conductors of all bits, 27 conductors and 28. The moisture reservoir to such a connection, the necessity of shunting spark gaps in each bit of days to a, disappears, it is enough and rubbing only the spark gaps of one bit as the potentials of the electrodes 1-7 on other holes in the gaps will be equal to the potential alu ifa electrodes of the surge arrester.

Multichannel multi gaming control. Its gaiter works in a very gentle way.

After applying the ignition pulse from the igniter generator 36 to the specrode 17 via conductors 27 and 28 and coupling capacitors 20-26

All glitches work independently of each other. The independence of operation is ensured by the same magnitude of all coupling capacitors, which A15 and the ignition pulse are charged in such a way as to increase the voltage at the spark gaps, which leads to their simultaneous breakdown on all parallel mounted arrays.

After a complete breakdown of one or several arresters, the operation of the remaining arresters is in principle possible as long as there is a voltage on them

5 the voltage of one spark gap. If only a part of the gaps tripped, the voltage on the remaining gaps decreases due to current flow.

0 by the discharge and the increase in voltage as a result of the load 33. For a stable parallel operation of the arresters, the instability in their response should

5 to be significantly less than the time for the voltage on the non-working dischargers.

Due to the resistors 29 and 30, the stability of the operation of one separate arrester is increased, which leads to an increase in the single-time operation of all the channels ...

Thus, the proposed

the arrester has a higher speed, increased accuracy of response time, stable switching operation at high frequencies

triggered by eliminating

floating potential at the electrodes. Performing a multi-channel arrester allows switching large currents, reduces the current density on the electrodes and decreases the inductance of the discharge circuit as a whole.
