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。
In view of the prevalence of power supply mode of using 1 transformer for both ground and underground electricity in small and medium-sized mines all over the world, the unreasonable power supply and hidden potential accidents are analyzed. A transformation scheme is proposed to solve the problem that a single transformer can not only Meet the requirements of the ground life and production system electricity, but also to meet the underground production system electricity requirements, reduce costs, reduce power consumption, access to good economic benefits.
