Abstract

Abstract: The impacts of the structure parameters of insulated shielding layer of 550 kV SF6 gas-insulated GIS bushing for high altitude localities on the electric field distribution is introduced. The impacts of shielding layer structure of different combinations of parameters on the maximum electric field strength are researched with the finite element method based on single shielding layer structure. And the impacts of shielding layer structure with different heights on the electric field distribution of the bushing are also researched. By optimizing the best shielding layer height and the best parameter combination of the shielding layer structure, the ideal internal and external electric field distribution of the bushing can be obtained. The internal and external electric field distribution of 550 kV SF6 gas-insulated GIS bushing for high altitude localities is thus effectively solved. A theoretical basis for design of 550 kV SF6 gas-insulated bushing insulation structure for high altitude localities is provided.

Key words: SF6 gas-insulated bushing, shielding structure, electric field calculation, high altitude, finite element method, APDL, optimization analysis
