Research on Electric Field Characteristics and Insulation Performance of the High-Voltage GIS Isolation Switch

Abstract:

In order to obtain the distribution law of electric field and the insulation performance of the insulators in ZF32-126 isolated ground module gas chamber, the three-dimensional electrostatic field of gas chamber was calculated and analyzed by using finite element software. The field strength focal point and the maximum field strength inside the gas chamber field can be obtained from the analysis of the electric field. Then the breakdown field strength of ZF32-126 isolated ground module was calculated according to the engineering practice limit formula. Thus the insulation properties of the isolated ground module can be determined by the breakdown field strength, and it can provide a theoretical basis and recommendations for the optimization of the internal structure of GIS device.
