摘要
针对一矿区35k V变电站电缆头着火引起的失压故障,分析了故障原因,是由于电缆头安装运行时间久,绝缘程度逐步降低,最终接地造成的;制定了今后的防范措施,以便更有效提高供电可靠性。
Aiming at the voltage loss fault caused by cable head ignition in a mine 35kV substation, the analysis showed the fault is due to the cable long time operation to decrease gradually the insulation degree, and result in the ground connection fault, made the preventive measures in the future;and effectively improved the reliability of power supply.
