Abstract
The utility model relates to a novel intelligent energy saving frequency conversion control system comprising a frequency converter and a soft starter, which are in a parallel connection. A rear part of the system is connected with a motor, and a front part is serially connected with a centrally controlled machine, and at the same time, a bypass is serially connected with the side of the system in order to guarantee the normal working of the soft starter. The rear part of the frequency converter is parallely connected with an output electric reactor and a direct current electric reactor. The control system has advantages of simple structure, easy assembly, stable performance, and convenient maintenance.
Description
Technical field
The utility model relates to the VFC field, is specially a kind of novel intelligent energy-saving frequency-changing control system of the power frequency that automaticallyes switch back.
Background technology
The application of frequency converter in industry more and more widely cooperates with Programmable Logic Controller at aspects such as air-conditioning, water supply, the hydraulic turbines especially and forms automatic control system, have energy-conservation, raise the efficiency, the advantage of intelligent operation, come into one's own day by day.
Because converter parameter is most important to system's operation, and converter parameter usually need be made amendment according to the requirement of system's operation.So converter parameter made amendment becomes the key link of the normal operation of safeguards system.And in the frequency converter operational process, through regular meeting the excessive problem of frequency converter failure tripping operation harmonic appears again, directly influence the operation of production equipment.Thereby research and development can prevent the frequency converter failure tripping grinder and further reduce the frequency converter harmonic wave, improve operational reliability, are the developing important topics of current frequency converter application technology.
The utility model content
The technical matters that the utility model solved is to provide a kind of novel intelligent energy-saving frequency-changing control system, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved adopts following technical scheme to realize:
The novel intelligent energy-saving frequency-changing control system can be installed on by the output motor side, comprises a frequency converter and a soft initiator; Soft initiator and frequency converter are for being connected in parallel; Its rear portion is used to connect motor, control machine during front end is then connected, simultaneously; For guaranteeing the soft initiator operate as normal, also be in series with a bypass on its side side; Said frequency converter then is parallel with out put reactor and direct current reactor at its rear portion.
In the utility model, said low voltage frequency converter has on the spot and distant place control function, can free of one anotherly switch with a distant place on the spot.A distant place is controlled through the DCS system of middle control machine, can control through touch screen or control knob that frequency converter carries on the spot.
In the utility model, frequency converter disposes out put reactor and direct current reactor, can effectively reduce harmonic wave and electromagnetic radiation.
In the utility model, said frequency converter is a low voltage frequency converter, is provided with automatic/hand bypass change-over switch simultaneously, when frequency converter breaks down, can switch to power frequency operation by automatic/hand; Can realize the reduced voltage starting load by automatic/hand control soft starter through bypass.
Beneficial effect: the utility model small investment, stable performance, easy to maintenance, can realize this locality and Long-distance Control neatly, do not cause the out of control of system and vibration during switching, its range of control is big, and control accuracy is high, and departure is little, is suitable for various motors.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the novel intelligent energy-saving frequency-changing control system of Fig. 1; In the present embodiment, frequency converter 5 rear portions are parallel with out put reactor 6 and direct current reactor 7, simultaneously; Frequency converter 5 self is parallelly connected with bypass 3 and soft initiator 4 again; Simultaneously, also be provided with control machine 1 and electric supply 2 among the DCS in the front portion of soft initiator 4 and frequency converter 5, then directly connect work drive motor 8 at soft initiator 4 and frequency converter 5.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
