Structural Optimization and Electric Field Analysis on the Insulation Structure of UHDV Wall Bushing

Article Preview

Abstract:

The insulation mechanism of UHVDC wall bushing is discussed. Design solution of the insulation structure is determined. In the solution, internal insulation includes SF6 gas-insulated and shielding structure, and external insulation is a type of composite insulating material, which is made up of epoxy FRP pipe and silicone rubber sheds. Creepage distance of external insulation and two types of shielding structures are designed in the paper. Finally two types of shielding structure are compared and optimized based on electric field simulation, and the result shows that dual-plate grounded shielding can enable the electric field strength of UHVDC wall bushing more evenly distributed.
