摘要
基于理论分析和实地测量,阐述低压线路对地故障的电气特征,在多方位考虑下研制了一套测量装置,其主要原理是用电流巡迹法、辅助“二分法”选点测试。实践证明,此装置在现场使用中效果良好,查找时间短,对永久性单相对地故障查找准确。
Based on theoretical analysis and field measurement,this paper expounds the electrical characteristics of low-voltage line to ground fault,and develops a set of measurement device under multi-directional consideration.Its main principle is to use current patrol method and auxiliary"dichotomy"point selection test.Practice has proved that the device has good effect in field use,short search time and accurate search for permanent single phase to ground fault.
