摘要
本文在分析现有检测直流系统接地故障方法的基础上,提出了一种在直流母线上注入两个不同频率的低频电压信号检测接地故障点的新方法。采用该方法制作的检测装置在现场试验中取得了满意的结果。
In this paper, Based on the analysis of present methods used for detecting grounding faults of D.C.System, a new method determining grounding fault points by feeding two different low-frequency voltage signals to DC bus is advanced. This method has been sucussfully used in the corresponding device which achieved satisfactory result in practical tests.
