| Abstract: | This paper presents a finite element calculating method of 3-D electric field in a complicated structure. In this method, subdomain structure and isoparametric coordinate transformations are applied. The automatic mesh generation of computing region is achieved by subdomain relating matrix. The 3-D electric field in deion plate arc quenching chamber of small-capacity contactor and that in the tank of SF6 circuit breaker are calculated. The results show this method may be tised to solve real engineering problems. |
