| 摘 要： | 本文从描述真空电孤等离子体的基本控制方程出发,推导出可以用来计算燃弧过程中电弧基本参数的电弧数学模型。计算结果显示:真空电弧从阴极开始沿轴向的逐渐收缩,导致了电流密度、电场强度和电弧电压显著增加,这种收缩与电弧电流、电极开距和纵向磁场有很大关系。这与实验结果是基本吻合的。

| Abstract: | On the base of the basic control equations to describe a plasma-colum (arc-column) of vacuum arc, the column model, which can be used to calculate some parameters of the plasmacolumn during arcing, were established. The calculation shows that the arc radius tends to decrease with increase in the distance away from the cathode The constriction close to anode is the most serious, and strongly dependent on the arc current, axial magnetic field and gap length- The calculations is approximately coincident with experiments. v |
