摘　　要：在煤矿井下高压供电系统中,漏电故障容易诱发瓦斯和煤尘爆炸,严重威胁煤矿的安全生产。应用MATLAB中的SIMULINK平台仿真矿井在高压供电系统中发生漏电故障时的零序电流和零序电压波形,分析煤矿高压供电系统中各线路的零序矢量关系,为研究煤矿漏电保护技术提供一种判断依据。In the underground high-voltage power supply system of coal mine,leakage fault is easy to induce gas and coal dust explosion,which seriously threatens the safety of coal mine production.Using the SIMULINK platform of MATLAB to simulate the waveform of zero sequence current and zero sequence voltage when the leakage fault occurs in the high-voltage power supply system of coal mine,analyzes the zero sequence vector relationship of each line in the high-voltage power supply system of coal mine,and provides a judgment basis for the research of the leakage protection technology of coal mine.
