Simulation of electromagnetic Phenomena in Vacuum interrupter with axial magnetic field type by Arc

아크 발생에 의한 축자계형 진공인터럽터의 전자계 현상 시뮬레이션

In this paper, we performed analysis of electric field, magnetic field, current density in AMF electrode using the Maxwell 3D simulation. The current distribution and magnetic field in simple models are analyzed to verify its efficiency and accuracy. In the vicinity of the slits of axial magnetic field type electrode a comparatively high axial magnetic flux density existsIn addition the validity of FEM is confirmed by performing the analyses of distribution in current density and magnetic flux density.
