Design of Overhead Line Fault Indicator with Partial Discharge Monitoring

文章设计了一种新型的架空线配网故障指示器,用于监测输电线路的局放及实时运行参数,及时发现预防线路绝缘及短路故障。该装置充分利用故障指示器安装于架空线导线的位置优势和直接测量配电电流的功能优势,提出一种基于超声波局部放电监测原理和GPS/BD同步对时技术的架空线配网故障指示器,解决配网架空线路故障前监测预警和故障后精确分析的问题。

In this paper,a new type of overhead line distribution network fault indicator is designed to monitor the running status of transmission lines and respond to faults in a timely manner.This equipment takes advantage of the location advantage of the fault indicator installed on the overhead line conductor and the functional advantage of directly measuring the distribution current,and proposes an overhead line distribution network fault indicator based on the principle of ultrasonic partial discharge monitoring and GPS/BD synchronous time synchronization technology,so as to solve the problems of monitoring and early warning before distribution network overhead line failure and accuracy analysis after failure.
