摘　　要：对特高压站内一起断路器操作回路故障现象进行了分析,指出防跳继电器故障时,操作回路中的跳闸监视回路与防跳回路存在寄生回路的问题。通过现场问题整改与分析论证,提出了断路器防跳回路验证的办法与建议,为特高压断路器二次操作回路的安全、可靠运行提供依据。The fault phenomenon of a circuit breaker operation loop in the UHV station is analyzed.When the antihopping relay fails,it points out the problem of parasitic loops in the trip monitoring circuit and the anti-hopping circuit in the operating circuit.Through the rectification and analysis and demonstration of on site problems,the methods and suggestions for the anti-hopping circuit verification of circuit breakers are proposed,which provides a basis for the safe and reliable operation of the secondary operation circuit of UHV circuit breakers.
