In the manner, the variable-frequency speed regulation device disclosed by the invention is suitable for a high-voltage motor, so that the resistance is lowered in a control process; the system efficiency is improved; the alternating current energy output by the variable-frequency speed regulation device can meet the requirements; and the reliability and the safety of a system application are improved.
Description
Technical field
The present invention relates to the field of electronic product, particularly relate to a kind of RHVC.
Background technology
Along with the development of power electronic technology, RHVC is widely applied on high-tension motor.Current new plant, Important Auxiliary equipment, as blower fan, water pump etc., generally all requires to consider that configuration frequency converter drags high-tension motor; Increasing built power plant is carrying out or is completing the transformation that high-tension motor adopts frequency converter.After high-tension motor adopts frequency converter to drag, how motor protection configures guarantee unit safety is run reliably, becomes the problem of power plant, designing institute, the concern of protection producer.
The appearance of variable-frequency governor, the requirement of the adaptive load rotating speed of high-tension motor can be realized, but still there is various problem in existing frequency control way, causes the effect after frequency control not fully up to expectations.Meanwhile, because the waveform harmonics composition of variable-frequency governor output voltage is comparatively large, peaked wave is many, has very large impact like this to the winding of high-tension motor, the winding of high-tension motor will be made in the course of time to lose efficacy, even burn high-tension motor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of RHVC, be applicable to high-tension motor, make it to reduce resistance in control procedure, improve system effectiveness, the AC energy making it export more can meet the requirements, and improves the reliability of system utilization, fail safe.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of RHVC, comprise controller, frequency converter, signal projector, compressor and pressure transmitter, described frequency converter carries out communication with controller and signal projector respectively and is connected, described signal projector carries out communication respectively by multiple compressor and pressure transmitter and is connected, and described pressure transmitter also carries out communication with controller and is connected.
In a preferred embodiment of the present invention, described controller adopts PLC.
In a preferred embodiment of the present invention, described RHVC also comprises adjuster valve, and described adjuster valve is separately positioned on compressor.
In a preferred embodiment of the present invention, the quantity of described adjuster valve is corresponding with the quantity of compressor.
The invention has the beneficial effects as follows: RHVC of the present invention, is applicable to high-tension motor, make it to reduce resistance in control procedure, improve system effectiveness, the AC energy making it export more can meet the requirements, and improves the reliability of system utilization, fail safe.

As shown in Figure 1, the embodiment of the present invention comprises:
A kind of RHVC, comprise controller, frequency converter, signal projector, compressor and pressure transmitter, described frequency converter carries out communication with controller and signal projector respectively and is connected, described signal projector carries out communication respectively by multiple compressor and pressure transmitter and is connected, and described pressure transmitter also carries out communication with controller and is connected.
In above-mentioned, described controller adopts PLC, is widely used in current industrial control field.Programmable logic controller (PLC) (ProgrammableLogicController is called for short PLC), a kind of digital electronic device with microprocessor, for the digital logic controller of Automated condtrol, can load control command at any time in internal memory and store and perform.Programmable Logic Controller is by innernal CPU, and the unit institute modularities such as instruction and data internal memory, input-output unit, power supply module, digital simulation are combined into.
Further, described RHVC also comprises adjuster valve, and described adjuster valve is separately positioned on compressor, and wherein, the quantity of described adjuster valve is corresponding with the quantity of compressor, makes it to reduce resistance in control procedure, improves system effectiveness.
In sum, RHVC of the present invention, is applicable to high-tension motor, makes it to reduce resistance in control procedure, and improve system effectiveness, the AC energy making it export more can meet the requirements, and improves the reliability of system utilization, fail safe.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
