摘　　要：刀闸是变电站一次系统中的重要设备,当刀闸在分合闸操作中发生异常停止时,有可能造成弧光短路,甚至还会造成大面积停电事故,因此研究刀闸的异常处理对变电站的安全运行具有重要意义。对一起变电站刀闸操作异常事件进行了深入探讨,描述了故障排查过程,并对刀闸异常的原因进行了分析,最终提出了解决措施,对运维人员在倒闸操作中快速处理类似异常具有一定的借鉴作用。The knife switch is an important equipment in the substation system.When the knife switch stops abnormally during the opening and closing operation,it may cause arc short circuit and even cause a large area of power failure.Therefore,it is of great significance to study the abnormal treatment of the knife switch for the safe operation of the substation.In this paper,the fault troubleshooting process is described,and the causes of the abnormal events of the knife switch are analyzed.Finally,the solution measures are proposed,which can be used as reference for operation and maintenance personnel to deal with similar anomalies quickly in the operation of switching.
