In order to reveal the complex physical phenomena in the interrupting process of low voltage circuit breakers, a 3D dynamic MHD arc mathematic model is set up in this paper according to one simple arc chamber, which model emphasizing the interaction among airflow field, arc and electrical magnetic field, and taking account of the effects of joule heat, conduction, convection, radiation and lorentz force on airflow field in arc chamber. Using this mathematical arc model, complex burning process of 3D arc in arc chamber is simulated and a new approach will be created for optimization design of arc chamber in low voltage circuit breakers. Combining with simulation of arc phenomena, a corresponding arc chamber sample is made to testify the arc mathematical model.
