摘要

本文采用有限元法比较了3种不同消光装置电弧柱上的电磁力，并利用流体力学的阻力计算了电弧速度。每个模型均在100v下进行断弧实验，测量断弧时间。并与计算值进行了比较，证实了理论的有效性。因此，本文提出采用u型栅格可以缩短电弧时间，提高电性能。并提出了一种比较分析仿真与实验结果的方法。

DC arc extinction using external magnetic field in switching device

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.
