摘要

本文提出了一种利用磁调制原理检测直流系统接地故障的新方法。该方法不仅可以确定单个漏电回路，而且可以通过在直流母线中插入电阻来确定正负母线同时绝缘故障的特殊情况。最后，本文给出了较好的结果。实验表明，该检测装置的选择回路性能良好，抗干扰能力强，对直流系统无影响。

The new method of monitoring DC system insulation on-line

A novel method of detecting an earth fault on a DC system is by the principle of magnetic modulation is proposed in the paper. The method can determine not only individual leakage loop but also the special case of both positive bus wire and negative bus wire insulation fault simultaneously by putting a resistance into the DC bus. Finally, the good results are shown in the paper. The performance of the detecting apparatus is good in the selection loop and strong in anti-interference, as well as it not showing any effect on the DC system through the experiment.
