Abstract： Switching equipment such as circuit breakers constitutes the focus and difficulty of current research in the field of DC power transmission and distribution. Switching arc is an important factor affecting the performance of equipment such as circuit breakers. Based on the theory of magnetohydrodynamics （MHD）， a simulation model of DC arc under the influence of sound field was established. Through the coupling simulation of multiple physical fields， the characteristics and correlation between each physical field and the DC arc under the influence of the sound field were studied， and the simulation results were verified by experiments.

Keywords： DC arc; magnetohydrodynamic model; multi-physical simulation; simulation analysis; sound field
