摘要
井下低压供电主要在采煤区,一旦发生供电故障极易引发安全事故。分析了井下变压器,移动变电站,混合式等三种供电正常运行、故障运行情况,确定了井下低压最佳供电方式,消除了漏电安全隐患,降低了企业生产成本,提高了经济效益,确保了煤矿井下安全生产。
The underground coal mine power supply mainly distributed at coal mining area. Once the power supply failure, it easily leads to accidents. The normal and fault operation situation of three types power supply such as underground transformer, mobile substation and hybrid-powered supply are analyzed. The best power supply method is determined, which eliminates leakage security risk, reduces production cost, improves economic efficiency and ensures coal mine safety production.
