直流电桥在小型变电站直流系统接地中的应用

The Application of Direct Current Bridge in Direct Current System Earth-fault of Small Transformer Substation

针对小型变电站的直流系统接地故障的特点,根据直流电桥原理进行分析,提出了一种迅速确定故障点位置的方法。

In terms of the characteristic of small transformer substation when direct current system meet the earth,according to the theory of Direct Current Bridge and analyzing,the paper put forward the rapid location of determining the current faults.
