基于改进模拟电荷法的真空灭弧室电场数值研究

he traditional charge simulation method (CSM) is studied in this paper, for solving its shortcomings, such as tedious complex preprocessing, the artificial influence considerations and their effects on the numerical calculation precision of electric field, a geometric feature CSM (GFCSM) is proposed. According to the geometry feature of electrical apparatus, the matching relationship of contour points and simulation charges has been established, and higher calculation precision of electric filed has been achieved. For verifying the feasibility and validity of the GFCSM, the unbounded electric field of vacuum interrupter with thin shielding floating electrode has been calculated, and the distribution of electric field has been illustrated. Moreover, a novel numerical strategy for solving the electric field has been provided
