110kV综自变电站控制回路红绿灯无指示的故障诊断方法

对于电力系统110kV综合自动化变电站内运行中多发的故障之一——控制回路中断路器位置无红绿灯指示现象进行了初步的分析。文章主要针对110kV综自变电站中着遍使用的四方公司SCX-11型操作箱的控制回路展开讨论,对110kV综合自动化变电站内运行中多发红绿灯无指示的故障提出了诊断思路和方法。

For the failure of the control circuit breakers of electricity system in 110kv synchronism substations,we analyzed the indicating light failure in the control loop.The diagnosis and solutions of the failure were proposed by discussing the control loop of the SCX-11 operation box.
