中小型矿山供电系统的现状分析与改造

Analysis and reconstruction of current power systems in medium and small mines

针对各地中小型矿山普遍存在采用1台变压器同时供地面和井下用电的供电方式的现状,分析了其供电的不合理性以及潜伏的事故隐患,提出了改造方案,解决了1台变压器既能满足地面生活及生产系统用电的要求,又能满足井下生产系统用电的要求,降低了成本,减少了电能损耗,获得了良好的经济效益。

Inview of the phenomenon that ground and under ground power supply are offered simultaneously with one same transformer in medium and small mines,the paper analys edits unreasonability and the hidden danger,and proposed the improvement scheme,thus both the household and production power consumption on the ground and the underground production power consumption can be satisfied with one transformer.So the cost reduces,power consumption decreased and excellent economic benefit obtained by the scheme.
