摘　　要：高压开关柜的电场分布会影响其绝缘性能,研究和改善高压开关柜中的电场分布是当今高电压技术的重要任务之一。基于有限元软件ANSOFT-MAXWELL对40.5 kv的高压开关柜内部电场进行3D建模仿真,并分析其静电场分布情况,采用MAXWELL自带的参数化和目标优化设计功能,对高压开关柜内的结构进行优化设计,得到了使高压开关柜内部结构表面电场强度分布最均匀的结构值。Because the electdc field intensity distribution of high voltage switchgear has an important influence on the insulating prop- erty, the research on its distribution is one of the most important tasks in high voltage technology. This paper simulates and models the electric field of 40.5 kv switchgear based on finite element method with ANSOFT-MAXWELL 3D and analyzes the distribution of the electrostatic field. The functions of parametric analysis and target optimization in MAXWELL are used to optimize the structure de- sign of the high voltage switchgear and obtain the best average value of the electric field intensity distribution.
