N2  -  In this paper, a dynamic arc model based on MHD (Magneto Hydro Dynamic) equations for a high voltage (HV) SF6 interrupter has been investigated and analyzed. Moreover, for simulating the insulating performance and interrupting characteristics of the SF6 interrupter, dynamic variation of the arc, such as arc moving in the presence of Lorentz force have been established, and the compressibility and viscosity of SF6 gas in the whole interrupting course has been taken into consideration. The mass-fraction equation is introduced to the model on the basis of traditional mass, momentum, and energy-balance equations. The distributions of temperature field, pressure field, and mass fraction in the arc chamber are calculated.
