摘要
通过对三相异步电动机常见故障──缺相运行的电磁现象及产生的危害分析 ,设计了缺相运行的保护电路 ,克服了传统机械式保护电路的不足 。
The electromagnetic phenomenon and its risk caused by a common fault, the phase missing running of triphase asynchronous motor are analyzed. A protection circuit for this problem is designed. The circuit overcomes the shortcomings of the traditional mechanical protection circuit, and ensures the safe running of triphase asynchronous motor.
