高压隔离开关缺陷分析及维护

Analysis and maintenance to the High- voltage isolation switch defect

高压隔离开关是变电站的常见设备，主要用于隔离高压电源，以保证检修的安全。通过对铜仁供电局近三年的关于高压隔离开关的缺陷统计分析，总结高压隔离开关运行中常见的缺陷类型、发生原因及处理方法，为高压隔离开关的运行维护提出一些建议。

High - voltage isolation switch is common substation equipment in the substation, mainly used to isolate high - voltage power supply in order to ensuring the safety of maintenance. Based on high - voltage isolator switch statistical analysis of defects which has happened nearly 3 years in Tongren Power Supply Bureau, the paper summarizes the common type of defects, causes and treatment methods in the high -voltage isolation switch operation and finally presents some suggestions to the maintenance and operation of the high- voltage isolation switch.
