摘要
通过对上湾煤矿四盘区综采工作面供电系统的方案比选,分析了系统内各个环节的电压损失及电压偏差,明确了引起电压偏差的主要因素及其对设备的危害,归纳总结了改善井下远距离用电设备电压偏差的技术措施。
Based on the scheme comparison of the power supply system of the fourth panel fully-mechanized mining face in Shangwan Coal Mine,this paper analyzed the voltage loss and voltage deviation of each state of the whole system,and pointed out the major factors causing voltage loss and the harm to equipment,and summarized the technical measures to improve the voltage deviation caused by long-distance power supply.
