Circuit processed, the third contactor formation third contactor holding circuit in parallel with High-speed Control button, third intermediate relay
The second contact shunt is interlocked with fire resisting damper and forms parallel circuit, and the stop button interlocks the first contact with the fire resisting damper, cuts
Switch, parallel circuit and third relay is changed to connect to form third control relay circuit.
In above-mentioned technical proposal, more specifically scheme be can also be；The motor is connected between the two-phase of power supply
Protector
Further；The first contactor connects to form low rate start indicating circuit with the first indicator light, and described second
Contactor connects to form high-speed starting indicating circuit with the second indicator light.
By adopting the above-described technical solution, compared with prior art, the present invention having the beneficial effect that due to this hair
It is bright that blower is controlled using double-speed motor, it can usually use slowspeed machine that blower is driven to come as the exhaust fan that subterranean layer is ventilated
With when a fire, with high-speed motor drive blower as fire control smoke exhausting use, a tractor serves several purposes has saved cost for enterprise.
Detailed description of the invention
Fig. 1 is control cabinet front view of the invention.
Fig. 2 is the principle of the present invention wiring schematic diagram.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples:
Fan controller shown in FIG. 1, including control cabinet are equipped with low speed stop button in the cabinet door of control cabinet
1SB, it stop button 3SB, low rate start button 2SB, stop button 3SB, High-speed Control button 4SB high-speed starting button 5SB, cuts
Switch SA, the first indicator light HL1 and the second indicator light HL2 are changed, the first intermediate relay 1KA, second are installed in control cabinet
Intermediate relay 2KA, third intermediate relay 3KA, first contactor KM1, second contactor KM2, third contactor KM3 and electricity
Machine protector BHQ, low speed stop button 1SB connect to form the first intermediate relay control circuit with the first intermediate relay 1KA,
First intermediate relay 1KA connects to form first contactor control circuit with low rate start button 2SB and first contactor KM1,
Low rate start button 2SB is in parallel with the second intermediate relay to form the first contactor KM1 holding circuit, stop button 3SB
With fire resisting damper interlock the first contact, High-speed Control button 4SB, high-speed starting button 5SB, second contactor KM2, among third after
Electric appliance 3KA, motor protecter BHQ and the second intermediate relay 2KA connect to form the second intermediate relay control circuit, open at a high speed
Dynamic the second intermediate relay 2KA holding circuit of button 5SB formation in parallel with first contactor KM1, stop button 3SB and fire resisting damper
The first contact, switching switch SA, High-speed Control button 4SB, first contactor KM1 and third contactor KM3 is interlocked to connect to be formed
Third contactor control circuit, stop button 3SB and fire resisting damper interlock the first contact, switching switch SA, third contactor KM3 and
Second contactor KM2 connects to form second contactor control circuit, third contactor KM3 shape in parallel with High-speed Control button 4SB
At third contactor holding circuit, third intermediate relay 3KA and fire resisting damper interlock the second contact shunt and form parallel circuit, stop
Only button 3SB interlocks the first contact, switching switch SA, parallel circuit and third relay 3KA with fire resisting damper and connects to form third
Control relay circuit.Element in Fig. 1 in dotted line frame is to be located at the indoor element of fire-fighting.
Motor protecter BHQ is connected between the two-phase of power supply.
First contactor KM1 connects to form low rate start indicating circuit with the first indicator light HL1, second contactor KM2 with
Second indicator light HL2 connects to form high-speed starting indicating circuit.
When the exhaust fan used time, press low rate start button 2SB usually, the coil of first contactor KM1 obtain it is electric, at motor
In low-speed running state, at this point, the first contactor KM1 normally-closed contact in third contactor control circuit disconnects, third contact
The coil of device KM3 cannot be powered, and blower is used as exhaust fan, when blower to be made stops, pressing low speed stop button 1SB,
First intermediate relay control circuit be powered, the coil of the first intermediate relay 1KA obtain it is electric, in control circuit first among after
The normally-closed contact of electric appliance 1KA disconnects, the coil losing electricity of first contactor KM1, motor power-off stalling, and blower is out of service.
When a fire, if being automatically brought into operation in the room that disappears, switching switch SA is got into automatic transmission, when fire resisting damper interlocks
When the second contact closure, third contactor control circuit obtains electric, the normally opened touching of third contactor in second contactor control circuit
Point closure, second contactor control circuit obtain motor and are in the state that runs at high speed, and blower enters fire control smoke exhausting state.When existing
Using when manual mode control switching switch SA is got to manual, at this point, press High-speed Control button 4SB, third is contacted
Device control circuit obtains electric, the third contactor normally opened contact closure in second contactor control circuit, second contactor control electricity
Rood electricity motor is in the state that runs at high speed, and blower enters fire control smoke exhausting state.When the temperature in the air duct of blower is greater than 300 degree
When, fire resisting damper interlocks the first contact and disconnects, and blower shuts down.Motor protecter BHQ is to motor in low speed turn to motor
It is protected.For motor in low speed turn, the first indicator light HL1 in low rate start indicating circuit is bright；Motor is in high speed turn
When, the second indicator light HL2 in high-speed starting indicating circuit is bright.
