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。
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.
