Abstract
The invention discloses a high-voltage grounding switch which is used in cooperation with a vertical type vacuum circuit breaker. In the using process, a linear drive device is started, a drive rod of the linear drive device extends outwards, a hinge pin moves upwards in a kidney-shaped hole, and through cooperation between the hinge pin and the kidney-shaped hole, linear motion is changed to be circular motion. A connecting plate drives a rotary shaft to rotate, accordingly, an extension arm rotates to drive reeds to rotate, and the reeds are moving contacts. When the reeds make contact with blades on the vertical type vacuum circuit breaker, working positions are switched to grounding positions, at the moment, the reeds, a flexible connecting line and a grounding part form a circuit, and therefore the grounding effect is guaranteed. When the reeds are separated from the blades on the vertical type vacuum circuit breaker, the grounding positions are switched to the working positions. Through a series of structural designs, the linear motion of the linear drive device is changed to be the circular motion of a rotary rod, and therefore automatic switching between the working positions and the grounding positions is achieved.
