摘要
Abstract
In order to study the advantages and disadvantages of detecting the partial discharge of in GIS (gas insulated switchgear) by the pulse current method, the ultrasonic method and the UHF method, using 220 kV GIS establish a set of GIS partial discharge detection platform. Application of the three methods, the three kinds of typical defects of the high voltage conductor tip, the ground electrode tip and the suspended tip are detected, access to a large number of experimental data and mappings. The test results show that the sensitivity of the pulse current method is higher, but the ability of anti-interference is lower, and field application has a certain limitation; with regard to the ultrasonic method, the sensitivity is lower, but the ability of anti-interference }s higher, and both the ability of anti-interference and the sensitivity of the ultrahigh frequency is high, so it is suitable for the field detection. On the whole, many testing methods need to cooperate to comprehensive confirmation.关键词
