高压断路器液压操动机构储能电机控制回路改进

Improvement of energy storage motor control circuit of hydraulic actuator in high-voltage circuit breakers

高压断路器液压操动机构的常见故障是储能电机频繁启动。通过合理地设计储能电机的控制回路,减少了液压机构频繁启动的现象。

The fault of the mechanism of High voltage circuit-breaker is motor of storaging power high frequency starup.That rationally design control circuit of hydraulic mechanism reduce the fault that motor of storaging power high frequency starup.
