矿用供电系统漏电保护技术改造

摘要

近年来，我国煤矿的机电装备得到了较大程度的发展。但在煤矿掘进工作面掘进的过程中，经常会出现供电系统选择性漏电保护的问题，并因此对实际工作的开展造成了一定的影响。在本文中，将就煤矿掘进工作面供电系统选择性漏电保护的实现进行一定的研究。%In recent years, the coal mine mechanical and electrical equipment has got great development in China. But in the tunneling process of coal mine heading face, there is usually power supply system selective leakage protection problem, which has affected the actual work to some extent. This article studies the implementation of the selective leakage protection of coal mine heading face.
