Abstract :
Axial magnetic field (AMF) in a vacuum interrupter (VI) with cup-type electrode is calculated, which includes 3D static AMF, 3D harmonic AMF and induced eddy current in contacts. The current in the calculation is 100 A. The results show that harmonic AMF is different with that of the static AMF because eddy current exists. The eddy current influences the AMF distribution in the center area of contact most heavily, between the slots lightly, above the slots most lightly
