摘要

通过在简单的电弧模型中运用功率平衡原理可以证明

在给定电流时

电弧的直径愈小

则电弧电压愈高

石英砂中的电弧

正是由于被限制在熔体汽化后遗留下的很小空腔中燃烧

故电弧电压很高

从而具有强烈的限流和熄弧作用。

Abstract

For given current

it is shown that

the less the arc diameter

the higher the arc voltage. The arc burning in the quartz sand is constricted in small cavities

so the arc voltage is very high and the effects of limiting current and extinguishing arc are violent.
