Abstract

A novel numerical strategy of electric field computation based on conventional charge simulation method (CSM) was proposed, according to the geometric feature of vacuum interrupter (VI). The matching relationship of contour points and simulation charges can be conveniently established for different component structure using the proposed geometric feature CSM (GFCSM). For verifying the feasibility and validity of the GFCSM, the unbounded electric field of a 12 kV VI with thin shielding floating electrode was calculated using the GFCSM and finite element method (FEM), and the distribution of electric field has been compared and illustrated. The insulation property of the VI was obtained and simulated.
