相似法在CJ20-63A接触器磁系统设计中的应用

Application of Analogue Method in Designing CJ20-63A Contactor Magnetic System

介绍了在外国同类产品的基础上，利用相似法对我国新系列接触器CJ20-63A的磁系统进行设计，大大简化了设计过程，节省了新产品研制的费用和时间。

In this paper,introduces how to use the analogue method to design the magnetic system of CJ20-63A contactor by modifying the same type foreign product,and that will simplify the designing process,saveexpenses and time in the manufacture of the new product.
