应用麦也尔电弧数学模型研究石英砂中直流电弧的动态特性

STUDY OF THE CHARACTERISTICS OF THE ARC IN QUARTZ SAND BY MEANS OF THE MAYR'S MATHEMATICAL MODEL OF ARC

本文在试验的基础上,应用麦也尔电弧数学模型对石英砂中直流电弧的动态特性进行了研究,得出了石英砂中电弧时间常数的数值和变化的一些宏观规律以及石英砂中电弧的动、静伏安特性相差不大的结论。

Based on the experiments,the characteristics of DC arc in quartz sand are studied by means of the Mayr's mathematical model of arc in this paper.The values and the change rule of time constant of arc in quartz sand are obtained.And then,the conclusion that there are little differences between static and dynamic V-A characteristics of arc in quartz sand is drawn.
