摘要
阐述了矿井6KV电网中性点采用消孤线圈并电阻接地方式后,对电孤接地过电压的抑制作用及参数选择方法,同时给出了与此系统配套的选择性漏电保护方案。
This article discribes the overvoltage suppression after are grounding and the method of parameter selection, after the application of neutral grounding through arc extinguishing coil and resistance in mine 6kv electric network. At the same time, the selective leakage protective project compatible with this system is given out.
