Abstract
In this paper, the electromagnetic force acting on the arc column of 3 different type extinction units is compared using the FEM (finite element method) and the arc velocity is calculated by the drag force of the fluid mechanics. The experiment for breaking was performed in each model at 100 V in order to measure the arcing time. And its result was compared with computing values, the confirmed validity of theory. As a result, this paper proposes that the divided U-shaped grid is able to shorten arcing time and improve of the electric performance. And it suggests a methodology for comparing and analyzing the results obtained by simulation and experiment.
