电动机缺相保护与补相再运行装置

The Phase-absent Protection and Supplement of Phase to Run again for Motor

介绍电动机缺相保护与补相再运行装置，提出一种利用健全相电压，根据磁耦合原理耦合出所缺相电压补入电动机使电动机继续运转的方法，对提高电力系统安全运行水平具有重要作用。

： This paper presents one method to keep the motor running， using the sound phase voltage with magnetic coupling principle to create the missing phase of voltage． Its effect in improving the level of safe operation of power system is very important．
