摘要

通过理论分析表明

石英砂熔断器具有强烈的限流和熄弧性能的原因是

电弧被限制在熔体汽化后让出的很小的空腔中燃烧

其散发功率总是大于输入功率

因而它自动趋向熄灭。

Abstract

Using theoretical analysis it is obtained that the basic reason why quartz sand fuses have powerful limiting current and quenching arc performance is that the arc is limited in a small cavity to burn which appears after vaporizing fuse element

its dissipating power is always more than input power

then it automatically tends to quench.
