-48 V直流通信电源系统正极未接地故障的处理方法研究

Research on Treatment Method of-48 V DC Communication Power System Positive Ungrounded Fault

通过对-48V直流通信电源供电系统正极排未接地故障进行分类研究,并对各类型故障进行等效电路建模分析,提出一种在电源侧正、负极排与总地排模拟接入功率电阻,来进行各类故障排查定位的处理方法,实现在对现网通信设备影响最小的情况下,完成隐患排查和故障处理。

In this paper,through the classification of ungrounded fault of positive pole of-48 V DC communication power supply system,and the equivalent circuit modeling and analysis of various types of faults,a processing method is put forward to carry out troubleshooting and positioning by simulating connecting the power resistance of positive,negative and general grounding on the power side,so as to identify potential dangers and deal with faults in the case of the minimum impact on the existing network communication equipment.
