摘要: 为解决乌海能源公司由于煤矿井下环境恶劣,供电线路复杂,接头多,而发生短路故障引起越级跳闸,导致井下大面积停电的问题,文章阐述了各煤矿供电系统监测监控的必要性。详细介绍了乌海能源公司各煤矿供电系统存在问题为:各矿采购的开关数量较多、批次不一,厂家组成较多,导致开关保护整定匹配较难|并提出了解决方法为:应用电力监控及防止短路越级跳闸系统。该系统的应用保障了煤矿井下供电的可靠性、安全性。

Abstract: Wuhai energy company of the coal mine power supply system complex, due to the harsh environment of coal mine, the complexity of the power supply line, multi joint, prone to short-circuit fault, short-circuit override trip, resulting in underground blackout. Due to the iron ore purchase of switch quantity, batch is, manufacturers composition more, switch protection setting match is difficult, my company the power monito
