一起隔离开关遥控失败的原因分析与对策

Cause Analysis of and Countermeasures Against a Failed Remote Control of a Disconnector

针对某500 kV厂站在220 kV母线冷倒操作过程中多次发生母线侧隔离开关无法远方遥控的情况,利用排除法对遥控操作环节涉及的各设备进行检查分析,找出了遥控失败的原因。为防范类似事件再次发生,提出了防范措施,为今后分析处理隔离开关遥控失败提供思路。

Aimed at coping with the repeated situation that the bus-side disconnector cannot be remotely controlled during the 220 kV bus cold switching operation in a 500 kV station,the elimination method was used to check and analyze the equipment involved in the remote control operation,and the cause of the failed remote control operation was found.Preventive measures are proposed to reduce similar accidents and to provide ideas for the analysis and treatment of possible failed remote control of disconnectors in the future.
