| Abstract: | Low vohage circuit breaker is the most critical protection and control equipment in low vohage distribution system, and numerical simulation of low voltage arc is significant for the optimization of its design and the improvement of its breaking performance. The basic equations of the most popular arc model based on magneto- hydrodynamics were presented, and the existing arc simulation work in low voltage circuit breaker were reviewed and summarized from the aspects of arc commutation, arc splitting, radiation and turbulence. At the same time, the existing problems of the arc model were pointed out and recommendations for further investigations were given. |
