摘要
文章介绍了故障指示器检测短路和单相接地故障的原理,并将廉价的故障指示器与通信技术相结合,构建了一套廉价高效的故障自动定位系统,该系统可以在故障发生后几分钟之内报告出故障发生的位置,大大地缩短了故障查找的时间,全面提高了配电系统的供电可靠性。
Seeking of distribution network fault location takes a large part of distribution fault handling time, to shorten fault seeking time effectively is an important task for distribution network automation. This paper firstly introduced the principles of detecting short circuit and single - phase grounding fault using fault indicator, then introduced a fault auto - location systemwith high efficiency and low - price, which adopted the communieation technology combined with low price fault indicator. This system can report the fault location in a few minutes alter fault occurred, the time of fault seeking is shortened greatly, and power supply reliability of distribution system will be improved.
