Research on Electrical Insulating Property of Disk Insulator in High Voltage GIS Insulated Grounding Module

Abstract:

Along with the GIS(Gas insulated metal enclosed switch equipment) miniaturization and three-phase common box, GIS disk insulator electrical properties are getting more and more attention of designers. In order to provide the necessary data and the theoretical support to the insulation coordination design of the disk insulator in engineering, the electric field and the potential distribution on the disc insulator surface of 126 kV GIS isolation grounding module are carried out numerical simulation by using the finite element method. And the maximum field strength of simulation are compared to the allowable field strength values of insulators in engineering in order to see whether it has certain insulation margin, thus put forward the improvement scheme of disc insulator structure.
