降低线路电能损耗的中间供电法

A middle power supply method to reduce the electric curcuit energy loss

在矿山供电系统中普遍都采取一端供电的方式,造成线路损耗及压降都很大。结合唐山矿业公司变电站供电系统的改造,提出由一端供电改为中间供电,达到了降低线路电能损耗及压降的效果。

In the mining power supplying system,it is common to supply power from one direction which makes high curcuit electric energy loss and voltage drop.Comparing with the change of power supplying system of Tangshan Mining transformer substation,this article gives the middle power supplying method more than one direction.This method has reduced the electric energy loss and voltagd drop.
