浅谈漏电断路器在三相电动机缺相电路中的应用

On the Application of the Earth Leakage Circuit-breaker in the Missing Phase Circuit of the Three-phase Motor

通过对电工实习教学过程中所遇到的三相电路缺相而损坏电动机线圈的现象,对其保护电路进行对比分析,利用现有的元器件,改变保护电路的接法,使其电路更有效的快速达到保护电动机的目的。

Because of some phenomena occuring in electrical engineering practice, this paper gives a contrastive analysis of the protective circiuts, that is, making use of the current components, changing protective circuit＇s connecting method, making its circuit more effectively protect electric motor.
