基于有限元电场分析优化的双屏蔽触头盒

Electric Field Analysis and Optimization Design of Double Shielded Contact Box Based on Finite Element Method

基于有限元分析软件Ansys对电场进行仿真分析,对40.5 kV开关设备内重要的绝缘件—触头盒进行双屏蔽设计改进,优化了高、低压双屏蔽层的布置方式和伞裙分布,实现了触头盒的整体绝缘性能的提升。

Base on the double shielded design of the contact box an important insulating part in the 40.5 kV switch-gear,and the simulation of the electric field distribution by using the finite element analysis software Ansys,the lay-out of the high and low voltage double shielded layer and the distribution of the umbrella skirt are optimized,and the overall insulation performance of the contact box is improved.
