| Abstract: | This paper derives the mathematical representative of the pressure gradient in vacuum arc with an uniform axial magnetic field under stationary model and assumptions of local themodynamic equilibrium etc.. The paper analyses the influence of the axial magnetic field on the pressure gradient in arc. The paper advances the important mechanism that the axial magnetic field is able to raise the ability of switching off vacuum arc. |
