摘　　要：过大的电容电流一直是煤矿安全的首要问题，而如何消除电容电流带来的危险也是电力系统要解决的问题。论文分析了几种煤矿6～10kV电网中性点接地方式，说明对于煤矿6-10kV电网，现普遍采用中性点经消弧线圈接地方式。针对这种接地方式讨论了目前几种不同的消孤补偿装置原理，并分析了其优缺点。The over capacitance current is always the primary problem of the mine safety and how to eliminate the danger occurred from the capacitance current is a problem to be solved in the electric power system. The paper analyzed the several neutral grounding modes of the mine 6 - 10 kV electric power grid. The paper introduced the present common applied neutral grounding mode with are extinguished coil for the mine 6 - 10 kV electric power grid. According to those grounding modes, the paper had a discussion on the principles of the present different are elimination and compensation devices and analyzed the advantages and disadvantages.
