摘要: 从漏电电流的暂态、稳态、人身触电安全、电弧接地过电压方面对煤矿井下3.3 kV供电系统进行了全面的分析和研究,就漏电故障暂态过程参数进行了计算机仿真,给出了有关的技术数据,为深入进行中性点运行方式的研究提供了理论依据。Abstract: The paper analyzed and studied the character of 3.3 kV underground mine power system through steady-state leakage-current,transient leakage-current,body safety and arc grounding over-vol-(tage.) These transient fault parameters of grounding fault are emulated in the computer.Some technical(parameters) were presented.These providid theoretic dates for researching the method of neutral point in(3.3 kV) underground mine power system
