Abstract

A vacuum arc plasma mathematical model is built up on the basis of magneto-hydro dynamics (MHD) theory in this paper. Except for control equations of mass conservation, momentum conservation, energy conservation, Ohm´s law and Maxwell equations are added to construct the complete model. The equations are solved with Taylor-Galerkin finite element method. With the MHD model, the progress of the vacuum arc during the whole arc-cycle can be simulated dynamically and the influence of AMF on the vacuum arc can be investigated in more detail
