Abstract :
The electric field in three phase outdoor vacuum circuit breaker with different instant are calculated and analyzed by finite element method (FEM), taking the effects of floating shield, porcelain casing and silicon rubber insulation on the electric field distribution into account. The distributions of the electric potential and the equal electric field strength of whole domain with different instant are obtained. The electric field simulation of three phase outdoor vacuum circuit breaker is achieved. From the study on distributions of electric potential and equal electric field strength of three phase vacuum circuit breaker, the electric field influence between phases is reflected clearly
