基于附加直流电源的煤矿直流架线漏电保护的研究

Reserch on the Protection of Mine DO-line Leakage Based on the Additional DO Power Supply

本文分析研究了煤矿井下直流架空线电网产生漏电的原因,总结了漏电保护研究的现状,并在此基础上阐述了基于附加直流电源的煤矿井下直流架空线电网漏电保护的原理。

In this paper, on the basis of analyzing network and summarizing the researching status on additional D. C power supply and researching the reason of the current leakage with the underground D. C overhead of current leakage protection, ameliorate the current leakage protection technique based on additional D.C power supply.
