The phase sequence protector can be divided into two types: a contact phase sequence protector and a contactless phase sequence protector, depending on the actuator. The former uses an electromagnetic relay or an AC contactor as its actuator, and the latter uses a solid state relay (thyristor, IGBT, high voltage VMOS tube) as its actuator. The former uses the contacts of the electromagnetic relay or the AC contactor to break the three-phase power supply with the wrong phase sequence, and the latter uses the electronic component to cut off the wrong power supply. Therefore, compared with the former, the latter has the characteristics of fast response, no noise, no spark, long life, small volume and high mechanical strength. The former has the advantages of high breaking voltage, strong overload capacity and low price. Features.
