(54) HIGH-VOLTAGE SWITCH under the action of electrodynamic repulsive forces. The shutdown command is given to the igniter 10 bit of the igniter. The housing 1 is separated from the grounded base 11 by an insulating pipe 12 and in it is located the charging circuit of the capacitor 8. In the switch Hai of FIG. 1 it contains a current transformer 13, the primary winding of which is the conductor 4, connected to housing 1; The secondary winding 14 of the current transformer is connected to the full-wave rectifier, the driver 15, from which the battery 16 is charged through the load resistor 17, the overvoltage relay 18 and ef-o normally closed contacts 19. - an inverter 20 connected to the battery 16, the output of which is connected to the primary winding of the charging transformer 21. The charging circuit of the capacitor 8 makes it possible to charge it even when there is zero battery in the line, because the battery 16 disabling transmitted light by an optical method upravleyi unit 22 via the light guide 23 to the photosensitive device 24, actuators etc. present in the arrester operation switch 9. FIG. 2 differs from the switch in FIG. 1 by a charge circuit of a capacitor 8, made in the form of a voltage divider consisting of Series-connected condensers 25, 26 and 27, connected to earth on one side and to a conductor 4 on the other. One of the condensers, namely, 25, serves to power the charging transformer 21, and the capacitor 27, for example, to measure the voltage. The switch case 1 is connected to the conductors 5 through capacitors 28, serving jpiH to improve the voltage distribution. The capacitor 8 is pressed. In the open position, the housing 1. is at a high potential through the capacitor 28 to improve the voltage distribution, and since any of the conductors 5 is connected to an energy source line, the voltage appears again on the divider. The disconnection in this variant occurs as previously described by applying a signal to the igniter electrode 10 of the discharge capacitor 9. The formula is not invented 1. High voltage switch comprising a housing insulated from. earth using an insulating tube, contacts located in the housing, and a drive, rae. "Licking contacts made on the basis of a capacitor with a charging circuit from a transformer in a screw; and, a rectifier, a battery and an inverter, characterized by that, in order to increase the reliability of the switch, the transformer is designed as a current transformer located on the high voltage side, the secondary winding of the transformer being connected to the input of a capacitor charge circuit. 2.
