Numerical simulation of SF6 arc characteristics influenced by electrode erosion

Abstract

During the interruption process of SF6 circuit breaker, electrode erosion will occur inevitably, which leads to the contamination of pure SF6 and the alteration of arc characteristics. In the paper, to one puffer type circuit breaker, simulation studies are focused on the application of Spalart-Allmaras model for turbulence and species transport model for… (More)
