Abstract :
In this paper, a numerical simulation model for 252kV puffer circuit breaker is constructed, and a novel concept of transparent arc root is introduced to suppress the unwanted arc column contraction. The novel methods have been implemented into PHOENICS and verified successfully by measurement. The arcing process of N2 and SF6 in a circuit breaker is simulated under different conditions, and reasonable agreement between prediction and measurement for no-load and with-arc cases has been achieved.
