Abstract :
In order to investigate an SF6 circuit breaker arc under nonequilibrium conditions, a complete self-consistent kinetic model has been set up. The number of chemical reactions equals 87, involving 35 different species of the SF6 dissociation products and their ionized and excited states. The collisional-radiative (CR) model determines the plasma composition and the temperature simultaneously in one point. Additionally, the Boltzmann equation is solved to determine the electron impact parameters. Results for a free-recovering SF6 arc as well as the SF6 plasma exposed to electric fields are presented
