摘要：

This paper is devoted to study the influence of ferromagnetic material on are behavior in low voltage electric apparatus. With the self-programmed interface, one 2-D magnetohydrodynamic arc model can be developed based on the commercial software FLUENT and ANSYS, to study the vapor of ferromagnetic material effects on air arc behavior. Then, the corresponding interruption experiments are performed to verify the simulation qualitatively. It demonstrates that the vapor of ferromagnetic material is disadvantageous to are interruption characteristics. In addition, the influence of the size of the ferromagnetic splitter plate on are motion is simulated. It shows that the bigger splitter plate may accelerate the are motion.
