If only the contactor is used to judge the air-cooled full stop state, when the phase sequence relay fails, the normal running signal is sent to the controller, the contactor is attracted, the air-cooled is not fully stopped, the oil temperature is high, and when the contactor contact is attracted and then opened, the signal sent at this time is the normal attraction signal, the air-cooled is not fully stopped.
