三相交流电相位检测系统的设计与研究

摘要

针对三相电产品信息化、智能化发展趋势,通过对三相电相位检测技术的探索,提出了一种将单片机控制检测方式应用于三相交流电相序检测的方法,成功实现了对电气控制设备的判断错相,缺相,并显示和报警,并可记录故障次数,工作次数,工作时间,实现相位保护功能.模拟测试系统结果表明,系系较好地实现了三相交流电相序检测的实用化,小型化,数字化.%In accordance with the developing trend of the three-phase electric products upon intelligent and information requirements, through exploring the features of three-phase alternating current phase and the detection technologies, the three-phase AC phase sequence detection system based on SCM is proposed, which successfully determines the false phase, fault phase, displays, and alarms, records failure number, work number, working hours, and realizes phase-protection. The experimental results show that the system achieved utility, miniaturization, digitization of the three-phase AC phase sequence detection system.
