When numerical value change and generator voltage, electric current, the parameter such as frequency, and generating set start, and the big minor adjustment of throttle, engine puts out
The control of fire.
Fan operation circuit operation principle：L1.L2 in line map, L3, N are the power lines that generator disconnecting switch is drawn,
L1, L2, L3 line voltage are 380V, L1, and L2, L3 is L1 in 220V, circuit with N phase voltages respectively, and L2, L3 is connected on main exchange respectively
On the 1 of contactor KM1----KM6,3,5 contacts, 2,4,6 split-phases concatenation thermal relay KA1---KA6 to blower motor M1---
On M6 terminals, blower motor M1---M6 operations and the main circuit stopped being constituted.
Linear quadratic control circuit runs operation principle：
Blower motor M1---M6 operations are to provide the operation of 380V power supplys by generating set, even if using phase voltage 220V
Motor switch control is done, if having strict safety even if 220V control lines are introduced into Operation Van's driver's cabin and once occur dew electrical phenomena
Safeguard measure can also threaten driver's personal safety.It is real using DC24V relays are installed additional on 220V main contactors control circuit
Linear quadratic control is applied, driver's cabin control blower fan start and stop will be introduced with the equal 24V linear quadratic controls line of refitted car power supply, eliminate high
Piezoelectricity is introduced directly into driver's cabin and causes hidden danger to people and Che.
The circuit diagram of linear quadratic control main circuit A.C. contactor is using KM1 as row：KM1 magnet coils KC1 two ends, a termination
On normally opened group of DC24V relays K1-3 contact, on the other end concatenation normally closed points of thermal relay KA1, thermal relay KA1 is normal
Another point is closed to be connected on the N in circuit.Due in normally opened group of other end link of relay K1-3 on L1, thus main ac contactor
Device KM1 magnet coils KC1 is by DC24V relay K1-3 controlling switch states.
Power supply FY input termination circuit L1 and N are controlled, voltage is alternating current 220V, output V+ and V- is direct current 24V, control electricity
Lu Zhong, V+ concatenation startup knob STP1 are normally opened, and stop button ST1 is normally closed, and to K1 magnet coil C1 terminals, C1 loop connects
DC24V power supply V-, constitute secondary control loop, the K1-1 of relay is relay K1 adhesives self-lock switch point, and K1-2 is K1 works
Make status indicator lamp switching point, K1-3 is the switching point for controlling KM1 magnet coil KC1 break-make 220V power supplys.When blower fan starts, press
Lower start button STP1 is normally opened, and relay K1 actuating coils C1 obtains electric, K1-1, K1-2, and K1-3 is synchronously turned on, and K1-1 is by normally opened
It is normally closed, relay K1 self-lockings, K1-2 is by normally opened to be normally closed, and red led HR-1 goes out, and green indicating lamp HG-1 is bright, and K1-3 is by normal
Open to be normally closed, KM1 magnet coil KC1 obtains electric, main A.C. contactor KM1 adhesives, the correspondence of switching point 1 and 2,3 and 4,5 and 6 connects
It is logical, blower motor M1 work, press stop button ST1 it is normally closed when, relay K1 actuating coils C1 power-off, K1-1, K1-2, K1-3
Synchronous to disconnect, relay K1 releases self-locking, and K1-2 is gone out by normally closed for normally opened green indicating lamp HG-1, red led HR-1 points
It is bright, KM1 magnet coil KC1 power-off, KM1,1,3,5 and 2,4,6 disconnect, and blower motor is out of service.
If two groups of control buttons be separately mounted on generator set control box panel and driver's cabin journey remote controllers panel on.
SA is change-over switch.Connect constantly, six relay K7 magnet coils obtain electric, K7-1------K7-6 adhesives, DC24V positive poles lead to
Cross relay intermediate point and connect the startup of the blower fan of the control panel of generating set distribution box and stop button on railway carriage, control wind
Machine is run.When SA is that change-over switch disconnects, six DC24V relay K7 magnet coil dead electricity, K7-1------K7-6 releases,
DC24V positive poles connect the operation button of driver's cabin by relay intermediate point, and fan operation is controlled by driver's cabin, according to live real
Border situation needs to be changed.
Suspension hydraulic controls circuit operation principle：
Suspension hydraulic controls circuit in the same circuit of air-blower control, and principle is essentially identical, and ST opens for two-way reset long handle
Close, when handle is lifted, DC24V electromagnetic coil relays C8 obtains electric, K8 adhesives, KM7 magnet coils KC7 and circuit L1 is connected, KM7
Switching point connect hydraulic pump motor power supply, hydraulic pressure pump assembly 15 works, and blower fan suspension assembly rises, when handle unclamps, automatically
Rebound neutral position, DC24V relay C8 dead electricity, K8 disconnects, KC7 dead electricity, KM7 release-pushes point, hydraulic pressure pump assembly 15 stops
Work, because hydraulic pressure pump assembly 15 is provided with inactive state at check valve, hydraulic jack 12, hydraulic pump DC24V electricity when handle is pushed
Magnet valve coil C9 obtains electric, and magnetic valve is opened, and the oil of hydraulic jack is by magnetic valve 16 to hydraulic oil pump fuel reserve tank draining, and blower fan hangs
Hanging component declines, when handle unclamps, neutral position of rebounding automatically, and electromagnetic valve coil C9 power-off, magnetic valve 16 is closed, blower fan suspension
Component is static.Implement remote information transmission and blower fan to run using 24V DC relays linear quadratic control, be conducive to driver's operation
In grasp equipment operation information and maximally effective safety guarantee during standard operation, even more driver's operation in good time.
During operation, counter-rotating fan is provided with dextrorotation, derotation draught fan impeller 19,20, when rotating at a high speed, dextrorotation draught fan impeller 19
Wind Volume forward direction air draft, the reverse air draft of derotation draught fan impeller 20, two blade wheel structures and effect are different, because two to rotation
The adjacent docking of the impeller of high-pressure axial flow fan 2, two coaxial reverse rotations of impeller, natural wind passes through air inlet, is revolved in high speed
Become a full member under being acted on to impeller 19, produce high speed winds and carry out 2 pressurizations to derotation draught fan impeller 20, high-pressure blast is generated, by being oriented to
The high pressure wind of air outlet 9 is on road or place, during operation, and the ice crystal face of accumulated snow is scratched in high pressure by preposition snowplow 1 on ground
Waved under wind effect, because there is orientation angle on the high-pressure blast Jing Guo Dao Xianging and ground, the lateral high-pressure blast of the snow cover waved, which is oriented, to be blown
Walk, form a width wider clean road surface or place.
