摘　　要：高压开关是高压电网运行中必不可少的关键设备,主要作用是在开关正常运行状态下的高压电路中或在高压电位系统运行异常时第一时间切断电源,有效降低事故损害。因此,介绍了一起10 kV开关控制回路断线而跳位灯和合位灯都亮的故障案例,分析导致该故障现象的原因,并针对原控制回路存在的设计缺陷,提出了相关的解决方案。High-voltage switch is an indispensable key equipment in the operation of high-voltage power grid. Its main function is to switch off the high-voltage circuit under normal operation, and to cut off the power at the first time when the high- voltage potential system operates abnormally, which can effectively reduce the degree of accident damage. This paper introduces a fault case in which the 10kV switch control loop is broken and the jumper lamp and the position light are all on. The reason of the fault phenomenon is analyzed. According to the design flaws of the original control loop, related solutions are proposed.
