摘要
介绍电动机低电压保护的原理,针对DMP371微机电动机保护测控装置低电压保护误动作原因进行分析,采取改写DMP371微机电动机保护测控装置程序,解决低电压误动作的问题。
The mechanism of motor low voltage protection was introduced, and the reason of low voltage protection malfunction in DMP371 microcomputer motor protection and monitoring device was studied. By rewriting the program, malfunction problem was solved.
