摘　　要：以某地区550 kV变电站断路器机构箱防跳回路失效引发的断路器合闸回路断线为例,通过分析故障发生的原因及断路器机构箱防跳回路存在的问题,创新性地在断路器控制回路中增加了防跳监视回路,使防跳回路出现故障时可以第一时间发现故障位置,及时排除故障,提高工作效率。Taking the circuit breaker closing circuit break caused by the failure of anti-trip circuit of circuit breaker mechanism box in a 550 kV substation in a certain area as an example,an anti-trip monitoring circuit is innovatively added to the circuit breaker control circuit by analyzing the cause of the failure and the problems existing in the anti-trip circuit of the circuit breaker mechanism box.Thus,when the anti-trip circuit fails,the fault location can be found as soon as possible,the fault can be eliminated in time,and the work efficiency can be improved.
