摘要
在稳态模型和局域热力学平衡等假设下，推导了在均匀纵向磁场下真空电弧压力梯度的数学表达式，分析了纵向磁场对电弧压力梯度的影响，提出了纵向磁场能够提高真空电弧开断能力的一条重要机理．
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.
