摘要：

A novel combined improved Total Variation Diminish scheme (TVD) with Finite Volume Method (FVM) has been proposed and applied for calculating the N - S and K - epsilon equation of now field in SF6 circuit breaker under no-load breaking in this paper. And during the computing, tire influence of actual nozzle structure is taken into consideration. Through the computation and analysis of combined electric field and now field, the effect of gas now on the dielectric recovery characteristic with different multi-stage convergent-divergent nozzle structure and their effects on gas flow in high voltage SF6 circuit breaker have been obtained and analyzed.
