摘　　要：针对某500 kV升压站倒闸操作时断路器误跳闸事故进行分析,确定原因为安装调试期间,由于误接线,在断路器保护柜的跳闸回路中产生了寄生回路,在特殊状况下引发了断路器误跳闸事故。针对施工阶段极易发生的“误接线”提出了防范措施,为避免同类型问题再次发生提供借鉴经验。The circuit breaker mistrip accident during the reversing operation in a 500 kV booster station is analyzed.The reason is that during installation and debugging,due to misconnection,parasitic circuit is generated in the tripping circuit of the circuit breaker protection cabinet,which causes the circuit breaker mistrip accident under special conditions.In view of the"misconnection"which is very easy to occur in the construction stage,the preventive measures are put forward to provide reference for avoiding the recurrence of the same type of problems.

关 键 词：断路器 误跳闸 误接线
