摘要
漏电保护开关越级跳闸不仅影响居民正常用电,也给排查故障增加了难度。分析漏电保护的基本原理及采取多级漏保的优点,结合居民小区里三级漏保开关的运行现状,对越级跳闸的原因进行了分析,并提出了相应的改进方法。
The override tripping operation of leakage protection switches not only affects the residential electricity consumption,but also increases difficulties of troubleshooting. The basic principle and advantages of the multi-stage leakage protection are introduced, reasons of the override trip are analyzed combining status of three-stage leakage protection in the resident sub-district, and then corresponding improvement methods are proposed.
