智能型故障指示器在配网中的应用

Application of Intelligent Fault Indicator in Distribution Network

随着社会发展和人们生活水平的不断提高,提高供电质量和供电可靠性是每个供电企业都面临的最实际和迫切的需求。由于县城配电网存在点多、线长、面广及接线方式复杂多变等特点,因此在线路故障时,要靠配电运行人员沿线查线,直到发现故障点,且故障查找困难,难以保障及时恢复供电。近年来,线路故障指示器在10 kV配电线路上得到了广泛应用,减轻了巡线人员的劳动强度,大大提高了工作效率,缩短了停电时间。文中介绍一种集短路、接地监测、远程通信为一体的智能型故障指示器在德清配网中的应用情况。

With the development of society and the continuous improvement of peoples living standard, to improve the quality and reliability of power supply is the most practical and urgent needs of each power supply enterprises facing. As country distribu- tion network there are many points, the line is long, range is wide and wiring way is complex changeable and so on characteristics, when the line is down, it should depend on the distribution operators look up the line along the mute until discovery fault point, and fault finding difficulties, it is difficult to guarantee the power restored in time In recent years, the line fault indicator is widely used in 10 kV distribution network lines, it reduces the labor intensity of the line operators, greatly improves the work efficiency, and shortens the outage time This article introduced an intelligent indicator application in Deqing distribution network, collection with a short circuit, grounding monitoring, remote communication.
