真空灭弧室内部电场分布的分析与仿真

Analysis and Simulation of Electric Field Distribution of Vacuum Interrupter

真空灭弧室对于真空断路器的性能有具重要作用,为了了解真空灭弧室内部的电场分布情况,文中采用Ansoft Maxwell仿真软件搭建了真空灭弧室的电场数学模型,并利用有限元分析法进行分析,通过Ansoft Maxwell仿真软件得出的结果表明,有无屏蔽罩对真空灭弧室电场分布有着较大影响。

The vacuum interrupter is very important for the performance of vacuum circuit breakers. An electric field mathematical model of the vacuum interrupter is built using Ansoft Maxwell software and analyzed by the finite element analysis-method to study the electric field distribution inside vacuum interrupter. Ansoft Maxwell simulation results show that the shield of vacuum interrupter has great influence on electric field distribution.
