摘要
在塑壳断路器分断过程中存在着两种现象,电弧背后转移和过零重燃现象,这两种现象都决定了断路器的分断过程,且与灭弧室内电场分布有关。本文介绍了如何利用三维有限元分析软件ANSYS对电场分布进行分析计算,可以用来指导新型灭弧室的设计。
Phenomena of back commutation and re-striking when current goes through zero can be occurred during interrupting process of MCCB. Both have close relationship with electric field distribution in arc quenching chamber. The electric field distribution of these two cases with FEA program ANSYS was analyzed. It will be helpful to develop new type of arc quenching chamber.
