为了提高矿山生产效率,对工艺设备供电系统的可靠性、经济性和安全性,提出了更高的要求;工艺设备供电中断时间即使不长,也会造成重大的物力和财力损失。推广俄罗斯科学院乌拉尔分院矿业研究所的新型电气设备,可提高露天矿供电系统可靠性5～6倍,维护费降低7/8～11/12,配电网路电能损失降低118%。
In order to improve the mine production efficiency, the reliability, economy and safety of the process equipment power supply system are put forward higher requirements. If the power supply interruption time of the process equipment is not long, significant material and financial losses will also result. The promotion of the new electrical equipment at the Institute of Mining of the Ural Branch of the Russian Academy of Sciences can improve the reliability of open-pit mine power supply systems by 5 to 6 times, reduce the maintenance costs by 7 / 8-11 / 12, and reduce the loss of distribution network power by 118%.
