摘要
Abstract
AC withstand voltage test can effectively detect the defects in GIS equipment caused by the electric field distortion. The ultrasonic partial detection,as a good supplement to the AC withstand voltage test,can effectively detect the insulation weak-ness caused by free particle defect. In this paper,two cases of free particle defects in a substation GIS and a hydropower station GIS are given,and the influence of the withstand sequence of the three-phase common box GIS on the test workload and the de-fect detection efficiency is discussed. Thereafter,a solution is put forward to provide reference and guidance for GIS electrical e-quipment handover test.关键词
