Abstract:

An arc model considering contact erosion was established,and the energy equations were added,combined with moving grid technology to achieve multi-physics coupling.During the erosion process,the arc temperature,current and other related parameters change,and the parameter changes under the ablation conditions or under the common conditions are compared.The simulation results show that,due to the existence of corrosion,the arc is likely to reignite,which is not conducive to the extinguishing of the arc.The research in this article is of certain significance for establishing an arc model considering multiple physical factors.

Key words: arc, erosion effect, arc characteristics, coupling model
