Abstract

We present a method of the universal characteristics of electric arc as a mathematical basis for the heat-exchange electric arc model (HEEAM) in the processes of heating by an electric arc in electrical engineering. We consider application of this method in calculating the temperature characteristics of the wall-stabilized discharge arc column in the stabilization zone of an air-operating laminar plasma torch. We present an example of calculating the temperature profile of the wall-stabilized arc for a plasma generator with the diameter of the discharge channel of 5 mm operating in air at the arc current of 60 A and compare the results of calculation with the published data on the experimental studies of the plasma generator.

气动层流等离子炬稳定区弧柱的热特性

摘要

我们提出了一种电弧普遍特性的方法，作为电气工程中电弧加热过程中热交换电弧模型（HEEAM）的数学基础。我们考虑应用该方法计算气动层流等离子体炬稳定区壁稳定放电弧柱的温度特性。我们给出了一个计算放电通道直径为 5 mm 的等离子体发生器的壁稳电弧温度分布的例子，并在 60 A 的电弧电流下将计算结果与已发表的数据进行比较。等离子体发生器的实验研究。
