摘要
Abstract
Comparing with ultrasonic partial discharge detection method,ultra high frequency partial discharge detection method detects and locates internal discharge defects of GIS solid insulation with good effect,however,because internal discharge defect position and type can not be confirmed,equipment maintenance strategy according to this is difficult to ensure perfection and accuracy.So,this article research on combined method of ultra high frequency partial discharge and X-ray digital imaging defect detection for detecting internal discharge defects of GIS solid insulation,after solid insulation defects are detected and located by ultra high frequency partial discharge detection method,defects can be visual confirmed by X-ray digital imaging during equipment maintenance.In 110 kV GIS on-site detection of one 110 kV substation.This method successfully detects the electrical tree defect in the insulation rod of disconnector in a live detection of 110 kV GIS in a 110 kV substation,which indicates that the method is helpful to improve the detection and location effect of partial discharge in GIS solid insulation,and provides reliable basis for maintenance.关键词
