Description
Technical field
Motor control technology field is the utility model is related to, in particular to a kind of novel fan control system.
Background technology
Existing rotation speed of fan control, due to generator operation characteristic, generator output voltage stablizes generating driven
The working speed of the engine of machine influences very big.If engine speed changes, necessarily cause the shakiness of generator output voltage
It is fixed, rotation speed of fan fluctuation is ultimately resulted in, fan noise increase, causes client to complain.
Utility model content
The purpose of this utility model seeks to provide a kind of novel fan control system, and the system is by introducing Electric control
Device realizes the influence for eliminating engine speed change to rotation speed of fan, avoids because engine speed change causes rotation speed of fan ripple
Move, produce the problem of extraordinary noise.
In order to achieve this, the novel fan control system designed by the utility model, it include engine, generator,
Controller of fan and blower fan, it is characterised in that it also includes electric power controller, wherein, the flywheel output shaft of engine, which is fixed, to be connected
The input shaft of sending and receiving motor, generator AC energy output end connection electric power controller input, electric power controller it is straight
Flow the input of electric energy output end connecting fan controller, the whole AC energy output end connection wind of frequency-adjustable of controller of fan
The electrical energy inputs of machine.
Operation principle of the present utility model is:Realize change alternating voltage to stable DC voltage using electric power controller
Conversion:When engine peed stable, the alternating current of generator output is also stablized, and electric power controller changes stable alternating current
For galvanic current, now controller of fan input is stable, and rotation speed of fan is stable;
When engine speed changes, the alternating current of generator exporting change, electric power controller is by the exchange of change
Electricity is converted to galvanic current, and the now input of controller of fan remains in that stabilization, and rotation speed of fan continues to keep stable.
The utility model can effectively maintain the steady of controller of fan input direct voltage by setting up electric power controller
It is fixed.Avoid, because engine speed changes, causing voltage pulsation, the rotation speed of fan change ultimately resulted in.The present invention is ensureing blower fan
While stabilization of speed, the noise pollution caused by rotation speed of fan fluctuates is reduced, reduces client's complaint.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-engine, 2-generator, 3-electric power controller, 4-controller of fan, 5-blower fan.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
A kind of novel fan control system designed by the utility model, as shown in figure 1, it includes engine 1, generator
2nd, controller of fan 4 and blower fan 5, it is characterised in that it also includes electric power controller 3, wherein, the flywheel output shaft of engine 1
It is fixedly connected with the input shaft of generator 2, the input of the AC energy output end connection electric power controller 3 of generator 2, electric power control
The input of the direct current energy output end connecting fan controller 4 of device 3 processed, the whole AC energy of frequency-adjustable of controller of fan 4
The electrical energy inputs of output end connecting fan 5.
In above-mentioned technical proposal, the electric power controller 3 is used to AC energy being converted to direct current energy.Electric power controller
3 be match rice control SKAI45A2GD12 type electric power controllers.
In above-mentioned technical proposal, the controller of fan 4 is used to direct current energy being converted to the whole alternating current of frequency-adjustable
Energy.Controller of fan 4 is match rice control SKAI45A2GD12 type controller of fan.
In above-mentioned technical proposal, the input shaft of the flywheel output shaft and generator 2 of the engine 1 is fixedly and coaxially connected.
In above-mentioned technical proposal, the voltage of the direct current energy of the direct current energy output end output of the electric power controller 3 is
560V (during load change, it is allowed to short time 300~720V of fluctuation range, but require final stable in 560V).Electric power controller 3
The DC voltage of output is the stationary value of a closed-loop control by PID regulations.The frequency-adjustable of the controller of fan 4 is whole
The AC energy frequency range of AC energy output end output is 0~600Hz, and voltage is 0~387V.Above-mentioned direct current energy can be with
The whole AC energy of the frequency-adjustable after conversion is set to adapt to the need of work of blower fan 5.
The course of work of the present utility model is:
When the invariablenes turning speed of engine 1, alternating current voltage, the frequency stabilization of the output of generator 2.Now electric power controller
The DC voltage stability of 3 outputs, the output AC voltage frequency of controller of fan 4 is controllable, and rotation speed of fan is stable.
When the rotating speed of engine 1 changes, due to the mechanical kinetic energy output end and the machinery of generator 2 of engine 1
Kinetic energy input synchronous axial system, when the rotating speed of generator 1 changes, due to the working characteristics of generator 2, generator 2 exports
Alternating current also change.Electric power controller 3 is converted to the alternating current of change stable direct current output, due to air-blower control
