摘要
本文从四个方面作了论述,认为工作面供电能用3kV就不用6kV,并应与整个矿井供电网隔离,以提高供电的安全性与可靠性。并对高压电网的漏电保护及降低电弧接地过电压,提出了意见。
The paper discusses in many respects the point of safety, deems that if 3kV is available , 6kV may not be used. The power line must be isolated from the ehtire power network of the mine so as to improve safety and reliability of the power supply. The paper gives opinion on leakage protection against over-voltage due to arc-earthing.
