Operation Analysis and Choice of Low Voltage Power Supply at Underground Coal Mine
Abstract：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.
