摘要

本文建立了电弧流道模型，研究了电弧流道在不同电流水平和电阻下的运动特性。利用高速CCD相机对电弧运动进行了观察，分析了电弧流道电阻对电弧运动的影响。对平行极间电弧运动的实验结果表明，在一定的配置下，增大极阻力会降低电弧运动的速度。然而，随着电流的增大，这种效果逐渐消失。提出了一个简化的数学模型来解释电弧转轮的阻力延迟电弧运动的原因。在不考虑电弧的流体特性的情况下，可以进一步分析电阻的电弧延迟效应随着电流的增大而减弱的现象。

The influence of electrodes resistance on arc motion between a pair of parallel electrodes

In this paper, an arc runner model is developed to study behaviors of the arc motion for different current levels and resistance of arc runners. By using high speed CCD camera the arc movements are observed and the influence of resistor of arc runners is analyzed. According to experiment results of the arc motion between parallel poles, for the certain configuration the increase of the pole resistance can reduce the speed of arc motion. However, with the increase of the current, this effect fades gradually. A simplified mathematical model is proposed to explain the reason for the resistance of the arc runner delays arc motion. Without considering the fluid characteristic of the arc, further work may be done to analyze the phenomena that with the higher current, the arc delay effect of resistance fades.
