Abstract
An arc model has been applied in this paper to study the fundamental interruption environment of a 550 kV SF6 single-break tank circuit breaker. The full differential model takes into account of all important physical mechanisms and is implemented into a commercial Computational Fluid Dynamics (CFD) package, PHOENICS. The model takes a magneto-hydro-dynamics (MHD) approach and the governing equations are solved using the Finite Volume Method (FVM). Through the simulation, the flow velocity vector and mach number for capacitive current switching and short-circuit current breaking are analyzed, and flow dynamic characteristics are obtained. The simulation can provide helpful reference for the design of 550 kV SF6 single-break tank circuit breaker.
