摘　　要：随着电磁仿真技术的发展和在低压电器领域的应用,可以借助其对灭弧系统结构进行优化设计,从而改善磁场分布及磁吹效果,提高分断能力。利用磁场CAE仿真软件,对某紧凑型断路器灭弧系统进行在短路电流下、模拟分断电弧在不同自励磁场中效果进行分析,期望借此优化产品结构设计,以满足更高分断能力的要求。With the development and application of electromagnetic simulation technology in the field of low voltage apparatus,CAE software can be used to optimize product structure design.In this article,CAE technology is used to simulate one compact MCB under short-current condition,to judge the magnetic effect in different structure design scenarios.Using this way,some measures could be found to optimize the product structure design and improve breaking capacity performance.
