Abstract

The model of current distribution in arc roots comprising dotted current emitting sources is proposed. A new approach to the potential boundary conditions is discussed. The paper presents the qualitative analysis of the arc motion based on the electrical field model described. The main result is the dependence of arc motion characteristics on the arc root location on the electrode. The three regions of arc motion, the zone of accelerated arc motion, the zone of arc deceleration, and the zone of arc erosion are found. Results of modeling agree with experimental data.
直线平行电极间电弧运动的模拟
提出了由点状电流源组成的弧根电流分布模型。讨论了求解势边界条件的一种新方法。本文根据所描述的电场模型对电弧运动进行定性分析。主要结果是电弧运动特性与电极上电弧根位置的关系。发现了电弧加速运动区、电弧减速区和电弧侵蚀区三个电弧运动区。模拟结果与实验数据吻合较好。
