Abstract
The utility model discloses a special frequency converter for spinning, which belongs to the technical field of power frequency conversion. The special frequency converter comprises a main circuit unit and a control circuit unit, wherein the control circuit unit is connected with the main circuit unit through a signal wire; and a magnet ring is sleeved on the signal wire. In the special frequency converter for spinning, as the magnet ring has different impedance properties under different frequencies, the resistance of the magnet ring changes along with variation of the signal frequencies, so as to enable normal useful control signals to pass successfully and well prevent high-frequency interference signals from passing. Therefore, in the utility model, the control circuit unit can accurately control the power output of the main circuit unit according to a detected accurate signal and ensure the safe and reliable operation of the frequency converter.
Description
Technical field
The utility model belongs to electric power converter technique field, is specifically related to a kind of weaving tailored version frequency converter.
Background technology
Along with the development of electronic semi-conductor's technology, more and more science is controlled also in the startup of motor, operation, and adopting the sensorless vector frequency converter mostly is the power supply that alternating current machine provides voltage regulation and frequency modulation, realizes the exciting current and the separately accurately control of torque current of alternating current machine.In the actual design of frequency converter is used, as shown in Figure 1, avoid the influence of forceful electric power signal in the main circuit unit 1 for making control circuit unit 2 as far as possible; Improve the overall performance of frequency converter, usually main circuit unit 1 and control circuit unit 2 are designed to split formula structure, and present in the casing 4 that understructure is arranged in frequency converter; Help reducing the volume of frequency converter; Like this, just need holding wire 3 that control circuit unit 2 and main circuit unit 1 are coupled together, accomplish the transmission of the two control signal.
In practical application; Along with increasing of the various power consumption equipments of industrial occasions; Various electromagnetism clutters also increase gradually, if frequency converter is under the stronger environment for use of this electromagnetic interference, the electromagnetism clutter can be superimposed upon on the control signal in the holding wire 3; Make detection and control main circuit unit 1 that control circuit unit 2 can not be correct, cause frequency converter operational failure to occur and cisco unity malfunction.
Summary of the invention
The utility model technical problem to be solved provides a kind of weaving tailored version frequency converter, can improve the antijamming capability of control signal.
For solving the problems of the technologies described above; The technical scheme of the utility model is: design a kind of weaving tailored version frequency converter; Comprise main circuit unit and control circuit unit, control circuit unit connects main circuit unit through holding wire, it is characterized in that: be set with magnet ring on the said holding wire.
Preferably, magnet ring is manganese-zinc ferrite and/or nickel-zinc ferrite.
The beneficial effect of the utility model is:
1, because magnet ring has the different impedance characteristic under different frequencies; The resistance of magnet ring changes along with the variation of signal frequency; Thereby normal useful control signal is well passed through; Again can the good restraining high-frequency interferencing signal pass through realized that control circuit unit correctly controls the power supply output of main circuit unit according to detected correct signal, guarantees the frequency converter safe and reliable operation.
2, since the magnetic permeability of manganese-zinc ferrite several thousand to Henry up to ten thousand/rice, and the magnetic permeability of nickel-zinc ferrite is extremely thousands of Henry/rice of hundreds of, ferritic magnetic permeability is high more, the impedance during its low frequency is big more, the impedance during high frequency is more little.So when suppressing low-frequency disturbance, should select manganese-zinc ferrite for use, otherwise when suppressing High-frequency Interference, should select nickel-zinc ferrite for use; When magnet ring is manganese-zinc ferrite and nickel-zinc ferrite like this, both can have suppressed High-frequency Interference and also can suppress low-frequency disturbance, increase the width that suppresses interference band, better filtering electromagnetism clutter.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Like Fig. 2,3, shown in 4; The main circuit unit 5 and the control circuit unit 6 of the utility model are split-type structural; And present in the casing 8 that understructure is arranged in frequency converter, an end of main circuit unit 5 is provided with input wires terminal 13, and the other end is provided with output wiring terminal 12.Set gradually socket 10,11 in main circuit unit 5 and the control circuit unit 6; The two ends correspondence of holding wire 7 is provided with plug 14,15, and in the plug 14 insertion sockets 10 with holding wire 7 one ends, the plug 15 of the other end inserts in the sockets 11; Realize the signal transmission of main circuit unit 5 and control circuit unit 6; Wherein be set with magnet ring 9 on the holding wire 7, and this magnet ring 9 is manganese-zinc ferrite and nickel-zinc ferrite, because magnet ring 9 has the different impedance characteristic under different frequencies; The resistance that is magnet ring 9 changes along with the variation of signal frequency; Thereby normal useful control signal is well passed through, can be suppressed passing through of high and low frequency electromagnetic interference signal again, guarantee that control signal avoids disturbing.
During work, frequency converter after process main circuit unit 5 is carried out commutation inversion, outputs to power consumption equipment by output wiring terminal 12 through input wires terminal 13 incoming transport power supplys.Wherein the regulation and control of inversion output provide signal after through chip on the control circuit unit 6 and sequential operation; Output to main circuit unit 5 through holding wire 7; Realization is regulated and control the size of inversion output, and detection signal feeds back to control circuit unit 6 through holding wire 7 and participates in follow-up computing simultaneously.The magnet ring 9 that increases on the holding wire 7 has suppressed the stack of peripheral interference signal on control signal; Guaranteed that control circuit unit 6 can correctly control the power supply output of main circuit unit 5 according to detected correct signal, effectively realized the safe and reliable operation of frequency converter.
It is to be noted; Above-mentioned execution mode only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection range of the utility model.
