The composition such as detection unit microprocessing unit.IGBT cut-offs to adjust the voltage of out-put supply and frequency, root frequency converter close to the inner portion
Supply voltage required for it is provided according to the actual needs of motor, and then achievees the purpose that energy conservation, speed regulation, in addition, frequency converter
There are also many defencive functions, such as overcurrent, over-voltage, overload protection.With the continuous improvement of industrial automatization, frequency conversion
Device also has been widely used.Freezing trimming machine the degree of automation currently on the market is poor, and control system is inconvenient.
In the prior art, the switching cabinet of frequency converter, control cabinet, transformer case, frequency conversion power unit cabinet are independent cabinet body, space
Arrangement form is to be arranged successively；Switching cabinet and control cabinet, transformer case pass through control line, cable connection, frequency-converter power list respectively
First cabinet and control cabinet, transformer case pass through control line, cable connection respectively, and capacitor connects behind power cell, due to existing knot
The arrangement of structure causes mutual line long, staggeredly complicated, is not easy to assembly maintenance；It is IGBT in frequency conversion power unit cabinet, whole
Stream bridge, failure bypass module, resistance constant power element are all made of conventional conductor connections and are welded on bottom plate, Wu Faman
Sufficient converter module design requirement, it has not been convenient to expanded application.
Existing big-power transducer is not easy to install, and running temperature is high, influences service life.
Therefore, it is very necessary for inventing a kind of big-power transducer with heat sinking function being easily installed.
Summary of the invention
For in the prior art, defect existing for frequency converter, a primary object of the present invention is that providing one kind is convenient for
The big-power transducer with heat sinking function of installation.
In order to solve the above technical problems, the present invention provides a kind of high-power frequency conversions with heat sinking function being easily installed
Device, including installation card slot, refrigeration cassette, recirculated water cooling pipeline, frequency converter and water pump；The frequency converter back side is equipped with several installation cards
Slot, the frequency converter side are equipped with a refrigeration cassette, are equipped with refrigerating fluid inside the refrigeration cassette, water pump be connected to the refrigeration cassette and
Recirculated water cooling pipeline, the recirculated water cooling pipeline are arranged in the extexine of the frequency converter.The control section master of the frequency converter
Plate is controlled using Digital Signal Processing special integrated chip DSP as CPU；Motor is controlled using vector control mode calculating
All parameters control turn-on frequency and the time of power module unit to obtain the output frequency of frequency converter.
Preferably, the recirculated water cooling pipeline uses copper pipe or aluminum pipe.
Preferably, the installation card slot is made of aluminum alloy materials.
The present invention has circulating cooling pipeline in frequency converter Surface mulch, can promptly reduce the running temperature of frequency converter,
The frequency converter back side is equipped with card slot easy to install, can install rapidly, have the characteristics that disassembly easy to install.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is frame diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and embodiments of the present invention include but is not limited to
The following example.
To achieve the goals above, The technical solution adopted by the invention is as follows:
As shown in Figure 1, the big-power transducer with heat sinking function being easily installed, including card slot 1 is installed, refrigeration cassette 2, is followed
Ring water cooling pipeline 3, frequency converter 4 and water pump 5；4 back side of frequency converter is equipped with several installation card slots 1,4 side of the frequency converter installation
There is a refrigeration cassette 2, is equipped with refrigerating fluid inside the refrigeration cassette 2, water pump 5 is connected to the refrigeration cassette 2 and recirculated water cooling pipeline 3, institute
The extexine that recirculated water cooling pipeline 3 is arranged in the frequency converter 4 is stated, the recirculated water cooling pipeline 3 uses copper pipe or aluminum pipe, described
Installation card slot 1 is made of aluminum alloy materials.Wherein, N >=2；It is powered on to master control system, and makes master control driving according to given frequency
F0 operation；Master control system calculates the principal voltage modulation waveform of the driving of master control at this time, and sends the principal voltage modulation waveform to
Fiber optic adapter；Resulting principal voltage modulation waveform is divided into the identical secondary voltage modulation waveform in the road N-1 by fiber optic adapter,
And it is input to accordingly from control driving respectively.The present invention take full advantage of frequency converter input PWM wave it is completely the same, then can
The basic principle of duplicate input voltage is provided for motor, operating speed sensor is effectively avoided and speed signal turns
The requirement that square signal needs high speed accurately to transmit.The control section master control borad of the frequency converter uses the dedicated collection of Digital Signal Processing
At chip DSP as CPU；All parameters controlled motor are calculated using vector control mode, to obtain frequency converter
Output frequency, control power module unit turn-on frequency and the time.
The present invention has circulating cooling pipeline in frequency converter Surface mulch, can promptly reduce the running temperature of frequency converter,
The frequency converter back side is equipped with card slot easy to install, can install rapidly, have the characteristics that disassembly easy to install.
Using technical solutions according to the invention or those skilled in the art under the inspiration of technical solution of the present invention,
Similar technical solution is designed, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
