Abstract
It is well known that vacuum interrupters with axial magnetic fields (AMF) have higher interrupting capability. But as the interrupting current increases to some extent the vacuum arc still begin to constrict even uniform AMF is applied. From our previous research work [1], the high current vacuum arc could distribute more evenly on contact surface under non-uniform distribution AMF produced by means of introducing ferromagnetic material (iron) with certain shape to electrodes. The main work of this paper is to analyze the distribution of AMF in the interelectrode gap after introducing the ferromagnetic material with finite element method (FEM).
