Description

but the translational motion of the above tg and lever electrodes.

FIG. Figures 1 and 2 show the construction of a protective discharge device, consisting of a fixed base 1, on which a rack 2 is installed.

On the stand there are a telescopic spring-loaded carriage 3 and a spring 4, resting on the sleeve 5.

The hinged electrodes 7 with the discharge balls 8 at the ends and the petals 9 are hinged on the axles x 6. On the carriage 3 the drivers 10 are mounted, which are connected to the lever electrodes 7 by means of the axes 11.

Ti 12 with drivers 13 and 14 mounted on the carriage 3. The base 1, structurally made in the form of a bracket mounted on a magnetic starting device 15.

The protective discharge device is connected to the high-voltage object in parallel through the lobes 9, which are connected by wire with the lever electrodes 7.

The position is working when the spark gap between the balls 8 of the movable lever electrodes 7 is zero.

The protective discharge device is driven by the movable bar of the electromagnet, the magnetic starter 15 through the gigs 12, which, when moving downward, drive the carriage 3. The carriage 3, moving down, compresses the spring 4

and through the leads 10 leads to the lever electrodes 7, which are movably mounted on the fixed rack 2. The lever electrodes 7 are consumed and form a working spark gap, designed for an alternating current voltage of up to 50,000 volts. Through the bracket 1, the discharge device mechanism is fixed on the magnetic starter 15. When the high-voltage object is turned off, the electromagnet's bark, magnetic starter 15, moves to the “off-up” position with the additional help of spring 4 through bars 12, carriage 3 and leads 10 brings the discharge balls 8 of the movable lever electrodes 7 into contact, through which the residual high voltage is removed from the high-voltage object.

Subject invention

A discharge device for removing residual high voltage in high-voltage objects containing electrodes fixed on a non-cushioned base is different in that, in order to improve service safety, these electrodes are S-shaped and are hinged at their bottom with the base and the leads located on the spring-loaded carriage kinematically connected with the magnetic starting device.
