摘要
描述了一种简易的三相电路相序检测器,该检测器是由逻辑门电路构成,能够用于三相电路的相序检测和缺相检测。它可以在三相电动机的运行中用作保护装置,也可以作为电动机串级调速中的一种相序检测方法。
A simply detector of phase sequence used for three-phase circuit was described.This detector is made up logical gate circuit which can be used in phase sequence and lack phase detection of three-phase circuit.It may be used as protective device in the motion of three-phase motor and also a detective method of phase eaquence in the cascade speed adjusting of motor.
