N2 - Direct current (DC) circuit breaker is a crucial component for controlling and protecting the DC power system, especially in photovoltaic power generation system. It should switch off the DC load current. The motion process of the moving contact (arm) greatly affects the arc voltage and arc evolution process. Therefore, this paper focuses on the arc evolution process considering the motion of moving contact in a DC circuit breaker. A 2-D magneto-hydrodynamic (MHD) model of a miniature circuit breaker is built. Based on this model, the temperature distribution and airflow field distribution are obtained. The arc evolution process with two different structures is analyzed. At the same time, the results with arm motion and without arm motion are compared and analyzed. In addition, the related experiments are carried out. It turns out that the arc evolution considering arm motion is closer to the experimental results.
