Description

Blower fan water pump high-pressure frequency-conversion combination sideboard
Affiliated technical field
The utility model relates to a kind of blower fan water pump high-pressure frequency-conversion combination sideboard, and especially a kind of employing Iusulated gate semiconductor speed-sensitive switch power model (IGBT) is the blower fan water pump high-pressure frequency-conversion combination sideboard of main frequency conversion parts.
Background technology
The constant speed that the blower fan of widely applying in the industrial production, pump class etc. need carry out keeping in the electric drive system of Flow-rate adjustment control alternating current motor drags, and adopts baffle plate and valve to regulate wind speed, flow, pressure etc. mostly.This method has not only increased the complexity of system, has also caused the energy to waste in a large number.Therefore, people wish to adopt the ac motor speed control system to replace dc motor speed-regulating system always, and have carried out a large amount of research and developments.
Developed multiple ac motor speed control device for many years, as: stator variable voltage speed control, pole changing, slip regulating speed, electromagnetic coupler speed governing, tandem control, commutator machine speed governing etc.Though succeeding in developing of these governing systems obtained certain achievement, but still exist shortcomings such as speed adjustable range is narrow, loss is still bigger than normal, power factor is low, suitable load surface is narrow, thereby limited the application of these Alternating Current Governor Systems.
The utility model content
The purpose of this utility model is to provide a kind of speed-regulating range width, little, the suitable wide blower fan water pump of the load high-pressure frequency-conversion combination sideboard of loss.
The technical solution of the utility model is achieved in that switch cubicle 2, and frequency converter cabinet 3, control cubicle 4 are assembled in cabinet 1 inside of blower fan water pump with the high-pressure frequency-conversion combination sideboard, connects with the high-pressure frequency-conversion circuit by blower fan water pump between its inner each assembly.On the cabinet door of the cabinet student side of switch cubicle 2, frequency converter cabinet 3, control cubicle 4 below and two sides of combination sideboard cabinet 1 all have the heat radiation grid.The super large LCDs 9 that the frequency conversion combination sideboard is operated the controlled area button 10 of control and is used for man-machine interaction is installed on control cubicle 4.Switch cubicle 2 inside are divided into three layers, and primary cut-out 11 is installed on the upper strata, and common mode reactor 12 is installed in the intermediate layer, and I/O cable 13 is installed by lower floor.Frequency converter cabinet 3 inside are divided into two-layer, and IGBT modular assembly 15 is installed on the upper strata, and output precision 14 is installed by lower floor.
Aspect converter circuit, the interchange of high voltage converter input 16 process primary cut-outs 11 and rectification unit 17, filter unit 18, inversion unit 17 connects in turn, outputs to output load 20 at last.The Iusulated gate semiconductor speed-sensitive switch power model (IGBT) that inversion unit 17 wherein adopts is directly series connection each other.
The beneficial effects of the utility model are:
Because with switch cubicle, frequency converter cabinet and control cubicle are incorporated into and make in the combination sideboard that its floor space is little, be convenient to installation and maintenance.Simultaneously, because I/O cable is to install from the bottom of switch cubicle, thereby increased the flexibility of project reconstruction.
In addition, be critical piece because frequency converter partly adopts IGBT, make its speed adjustable range big and continuous, realize that easily forward and backward is switched and the formation automatic control system, starting current is little, can be used for Fraquent start and braking occasion.
