摘　　要：高压断路器是电力系统中最重要的设备之一,担负着控制和保护的双重任务。打压超时回路是高压断路器储能电机控制常见的回路,可有效监视电机储能工作是否正常。探讨了一起500 kV断路器电机打压超时故障,对该回路的改进提出了建议,同时介绍了常见的500 kV断路器打压超时原因和预控措施,为业内同行提供了参考。High voltage circuit breaker is one of the most important equipment in power system,which is responsible for the dual tasks of control and protection.Pumping timeout circuit is a common circuit for the control of energy storage motor of high-voltage circuit breaker,which can effectively monitor whether the motor works normally.In this paper,a 500 kV circuit breaker motor pumping timeout fault is discussed,and suggestions for the improvement of the circuit are put forward.At the same time,it introduces the common reasons and pre control measures for pumping timeout of 500 kV circuit breaker,which provides a reference for peers in the industry.
