The Calculation and Analysis of the 3-D Electric Field of the Disconnector Switchgear inside of a 110kV 3-Phase in One Tank Type GIS

摘要

The 3-D electric field near the gap of the disconnector switchgear inside of a 110kV 3-phase in one tank type GIS was calculated by means of charge simulation method in this paper. The three dimensional distribution graphs of the electric field strength on the surfaces of the electrodes were drawn and a simple method of drawing three dimensional distribution graph of the electric field strength on the cylindrical surface was presented. According to the graphs, the distribution and the uniform degree of the electric field strength can be observed easily.
