Abstract
We derived a theory of increasing electromagnetic force acting on arc column for reducing arcing time between electric contacts. A simulation method of arc velocity is presented by calculating blowout force using 3D FEM and drag acting on arc column. This paper is proposed 3 types arc extinguish chamber of different fulx path and is presented electromagnetic force and arc velocity of each model.
