摘要
针对煤矿供电系统中选择性漏电保护的问题,着重介绍了目前选择性漏电保护在不同中性点接地方式上的应用,阐述了中性点不接地系统下单相非金属性接地动作参数的选择。
In the light of the selective leakage protection in coalmine's power supply system,this paper emphatically introduces the current application of the selective leakage protection under different neutral-point grounding methods,and expounds the selection of action parameters of single-phase nonmetal grounding under isolated neutral system.
