[0002] Since the conversion of the four states (operation, hot standby, cold standby, and maintenance) of the 10KV circuit breaker requires a switching operation, the operator needs to manually use the trolley crank to shake the circuit breaker trolley to convert the circuit breaker from one state to another during the operation. There are many operations during major maintenance, and the operator's manual shaking of the trolley seriously affects the efficiency of the power outage operation, which is also a burden on the operator's body. In addition, the personnel cannot ensure that the circuit breaker trolley rotates at a uniform speed during the operation. When the operation is stuck, high-voltage electromagnetic resonance may be generated, which will cause the protection device to malfunction, resulting in a parking or flow reduction accident. Therefore, designing a device that automatically shakes the trolley to improve the efficiency of the power outage operation, reduce the physical burden of the operator, and reduce the risk of the operation process has become a technical problem that needs to be solved in this field.
