LOAD BREAK SWITCH DRIVE Russian patent published in 2018 - IPC H01H9/00 

FIELD: hardware engineering.

SUBSTANCE: invention relates to the field of high-voltage engineering. Drive of the load switch contains a block with a charge spring, fastened on both sides by plates, which rotate for switching on and off, in the direction of the force of the cocked spring. Driving lever is rigidly fastened to one of the plates of the specified block, the transmission mechanism in the form of a thrust with axes is connected to the load switch, the platoon levers act on the plates of the block, coil spring is made with a torsion spring, resting with its edges into the holes of the pins of the cocking levers separately for switching on and separately for switching off. Platoon levers are equipped with stop teeth locking the cocked edges of the spring before giving the command to turn on or off remotely or automatically. Force of the edges of the spring is transmitted to the switch from the axis of the block with a spring without intermediate links, which leads to a decrease in effort for cocking the springs.

EFFECT: technical result: simplified drive design, improved manufacturability.
