摘要:
提出了基于双端行波法、区段环流法、稳态差动法和GIS（地理信息系统）相结合的电力电缆在线故障定位系统。该系统由配电所电缆监测终端、电缆中间接头监测终端、电缆故障定位GIS展示平台和通信网络4部分构成。对于各种故障类型，系统均能够通过基于百度地图的地理信息系统展示故障点坐标位置。将多种在线故障定位方法和地理信息展示技术应用于城市轨道交通电力电缆在线故障定位，大大提高了电缆供电可靠性和运行维护管理水平。
Abstracts:
A power cable online fault location system based on the combination of double side electric wave method, segment circulation method, steady state differential method and GIS (geographic information system) is proposed. The system consists of four parts: cable monitoring terminal, cable intermediate connector monitoring terminal, cable fault location GIS display platform and communication network. For different fault types, the system can display the coordinate position of fault points through GIS based on Baidu map. The application of various online fault location methods and geographic information display technologies to the online fault location of urban rail transit power cable has greatly improved the reliability of cable power supply, the level of operation and maintenance management.
