摘要
变压器中性点不接地的供电系统中,各相对地存在分布电容。分析了在煤矿井下电网电容电流造成危害的主要原因,并且采取合理的控制方法减小其危害,从而为煤矿井下安全供电和安全生产提供客观依据。
In the unearthed transformer power supply system,there is relatively distributed capacitance.The main reasons for capacitive current harm in the coal mine has been analyzed.It will be taken reasonable control methods to reduce the harm,and provided an objective basis for the coal mine production safety and security of power supply.
