摘　　要：在分析了井下三相三线制配电网实现选择性漏电保护原理的基础上,提出了三相与单相负荷混合供电线路实现选择性漏电保护的原理,并进行了理论分析、Matlab仿真及各项实验。现场运行情况表明,采用该原理实现了可靠的选择性漏电保护。Based on the analysis of the theory to realize selective leakage protection for a three-phase three-wire distribution network system, a theory to realize selective leakage protection for a mix-power supply load system is proposed containing three-phase and single-phase load. The theoretical analysis, Matlab simulation, various experiment with emphasis are made. The running conditions on spot indicates that this theory can realize selective leakage protection reliably.
