基于 HFCT 局放测试技术的高压电缆终端失效检测方法研究
Research on failure detection method of high voltage cable terminal based on HFCT test technology of partial discharge
摘要
Abstract
In view of the high voltage cable terminal operation failure caused by defects , this paper analyzes the mech-anism of partial discharge , with the combination of AC variable frequency resonant pressure test by using the partial discharge test technology of HFCT ( high frequency current sensor ) , and designs a method to determine cable termi-nation happen failure state detect by monitoring partial discharge pattern of cable termination under different test volt -age.Through the field test , the terminal defect of high voltage cable is found effectively .The problem of high voltage cable project completion acceptance is solved through the application of the test methods , which can be effectively found in cable terminal completion inspection and acceptance imperfections , and have obvious effect on judging high voltage cable terminal failure in advance .It can avoid the failure caused by cable terminal malfunction even terminal head explosion accidents .关键词
