摘要
对斜沟矿井110 kV变电站二次设备直流系统电源结构和负荷情况进行了研究,分析了变电站直流系统存在的安全隐患,采用辐射式直流馈电网络对站内直流系统进行升级改造,应用智能化绝缘监测装置实现直流馈出线路实时在线监测,解决了变电站直流系统故障点难查找、难处理、失电范围大的难题,保障变电站的安全稳定运行。
The power supply structure and load situation of the DC system of the secondary equipment of the 110 kV substation in the Xiegou mine were studied.The hidden safety hazards in the DC system of the substation were analyzed.The intelligent insulation monitoring device realizes real-time online monitoring of the DC feed-out line,solved the problems of difficult search and handle,and large scope of power loss in the substation DC system,and ensured the safe and stable operation of the substation.
