Research of simulation and experiment on arc characteristics of gas mechanical switch
High Voltage, Volume 9, Issue 3, Page 626-635, June 2024.Abstract An arc is the high‐temperature discharge plasma produced in the opening process of mechanical switches, which directly affects the breaking capability of a hybrid DC circuit breaker. According to the physical mechanism of an electric arc, the construction of an arc model for simulation analysis is an important technical means in the electrical
