Embodiment one: referring to Fig. 1, a kind of double speed firefighting fan control cabinet circuit, including blower protector T1, blower are protected
Protect device T2 and phase sequence relay, the blower protector T1, blower protector T2 and phase sequence relay XJ pass through simultaneously power supply into
Line circuit breaker Q F is connected with power input, and phase sequence relay XJ passes through intermediate relay J3 while and low speed contact device, high speed
Contactor connection, manual/auto control device with low speed contact device, high speed contact device by being connected simultaneously by intermediate relay J4
It connects, pin 1, pin 3, the pin 5 of blower protector T1 and low speed contact device, pin 2, pin 4, the pin 6 of low speed contact device
It is connected by resistance with blower M, blower protector T1 is connected by intermediate relay J1 with low speed contact device, blower protector T2
With the pin 1, pin 3, pin 5 of high speed contact device, pin 2, pin 4, the pin 6 of high speed contact device are connected with blower M, blower
Protector T2 is connected by intermediate relay J2 with high speed contact device, blower M connection ground line.
Power input provides power input, the electric switch of electric power incoming line circuit breaker Q F power supply input circuit for circuit；Wind
Machine protector T1 is EOCR-SS type product (being also overcurrent protective device): detection circuit electric current, and current state signal is passed through
Intermediate relay J1 passes to contactor, contactor disconnecting circuit；Intermediate relay J1: the electric signal that motor protecter is generated
It is transferred to contactor；Low speed contact device (low current version): can be by receiving motor protecter, phase sequence relay fault-signal
Disconnecting circuit.By receiving the control signal of manual/auto control device, circuit is opened or closed.
The specific device of blower protector T2(is EOCR-SS type product (being also overcurrent protective device)): detection circuit electric current,
And current state signal is passed into contactor, contactor disconnecting circuit by intermediate relay J1；
