摘要
目前变电站普遍在隔离开关机构箱上加挂微机防误机械编码锁去闭锁隔离开关的操动机构,而这却给倒闸操作、运行维护带来了极大的不便,也容易造成开机构箱门维护时误碰分、合闸按钮导致误拉、合隔离开关的事故。针对此问题,本文对隔离开关操动机构的闭锁方式进行了研究,并提出了相应的改进方案。
At present,transformer substations generallyinstall the microcomputer anti-misoperation mechanical coder lock on the mechanism case of the disconnecting switchto achieve the purpose of blocking the operating mechanism.However,this mode brings great inconvenience to the switching operation and maintenance,and also easily causes accidents.Focusing on the above problems,this article studies the blocking modes of operating mechanism of the disconnecting switch and provides corresponding improvement schemes.
