摘　　要：通过理论分析和计算机仿真,成功解决了不同电压等级供电系统的零序电压的取样问题,实现了两种电压等级共用一套漏电保护系统的目标。重点介绍了"EDS-336/660集散式选择性漏电保护系统"的基本组成及其在单侯煤矿的实际应用情况。By the theoretical analysis and computer simulation, the problems of zero-sequence voltage sampling for power supply system with different voltage levels are successfully resolved, and the aim of sharing a set of leakage protection system by two different voltage levels is realized. This article mainly introduces the fundamental configuration and practical application of EDS-336/660 distributed selective leakage protection system in Danhou Coal Mine.
