三相异步电动机电源断相运行电压分析及保护

Protection and voltage analysis of three-phase asynchronous motor running in break phase

结合电动机断相保护误区 ,对三相异步电动机电源断相运行时 ,其端线电压及中性点对地电压进行了分析 。

Combining with motor breaking phase protection misunderstand, the end point voltage and neutral point opposite earth voltage of three_phase asynchronous motor running in break phase were analyzed here.The countermeasures for raising motor running and protection reliability in break phase were expounded,too.
