摘要
根据热路与电路相似原理,提出一种小型断路器双金属片热脱扣动作特性的计算新方法,与传统方法相比,计算准确性大幅度提高,介绍了以此立法为基础,研制的小型断路器热脱扣器计算机辅助设计软件.
The paper provides a new calculating method of thermal operation characteristics for MCBs on the basis of the similarity of thermo-circuit to electric circuit. The new method is more precise than traditional method. The paper introduces the CAD software designed according to the new method.
