Abstract :
Computer simulation is performed in a whole breaking period except the region of current zero of gas circuit breaker. The Euler equation is solved using the finite volume fluid in cell method. In order to consider the effects of arc, electric field intensity and radiation transport are calculated using the finite element method and the method of partial characteristics, respectively. Also, the quantity and the electrical conductivity of ablated nozzle vapor are calculated, and its effects are investigated through computer simulation. Improved simulation results are obtained and compared with the experimental one
