摘要
本文应用相似理论得出,真空灭弧室中电弧运动速度与电流强度成线性关系的相似准则,和极限开断电流与触头直径、开距间的经验公式。认为用小电流模型来研究大电流真空灭弧室是可行的。
Based on similitude theory, two conclusions which are very important in theory research and practical design of vacuum interrupters are drawn: 1)Arc moving speed is a linear function of current when the gap between contacts maintains as a constant;2) The limited interrupting current is also a function of diameter of contact and gap of that-
