摘　　要：提出一种用于复杂结构中三维电场数值计算的有限元法，指出采用子块法和参数变换法，通过子块关联矩阵来实现自动剖分，以适应求解区域结构的复杂性．采用这种方法对小容量接触器灭弧室和ＳＦ６断路器罐体中三维电场分布进行了计算，结果表明，上述方法完全可以用来解决实际工程问题．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.
