摘要
阐述了10kV配电网系统线路故障的判断方法,对故障寻找方法进行了分析和比较,并推荐使用基于信号注入法的小电流接地系统单相接地故障定位等新技术、新设备,缩短单相接地故障查找时间,确保配电网的安全经济运行。
Fault judging methods for overhead lines in lOkV distribution network are expounded, and the methods to locate single phase to ground fault are analyzed ＆compared. New technologies and new equipments for detecting the single phase to ground fault using signal injection in small current neutral grounding system are recommended, to shorten the time for detecting the fault and ensure the safety ＆ economic operation of the distribution network.
