摘要
液压机构因其具备的众多优点被广泛应用于高压断路器中,断路器频繁打压是液压机构断路器中常见的一种故障。文章针对一起500 kV断路器频繁打压故障,分析故障成因并提出相应的解决办法,同时简要分析其他几种致使断路器频繁打压的可能原因。
Hydraulic mechanism is widely used in high-voltage circuit breakers because of its many advantages.Frequent pressure of circuit breakers is a common fault in hydraulic mechanism circuit breakers.This paper analyzes the influence of temperature on the pressure of a 500 kV circuit breaker,the causes of the failure,and puts forward the corresponding solutions.At the same time,it briefly analyzes several other possible reasons for the frequent pressure of circuit breakers.
