Abstract: In order to improve the insulating ability of post insulators which was used on common box bus of 252 kV gas insulated switchgear (GIS), this paper carried out computational analysis of the electric field of insulation surface and inside, researched on the influence of post insulator climbing group on the electric field along the surface and carried out insulators optimization design. The insulation test of the optimized structure verifies the rationality of optimization design, which improves the insulation ability of post insulator.
Key words: post insulator; electric field analysis; insulating ability improvement
