Abstract
The utility model discloses a filter reactor comprising iron yokes arranged at the top and the bottom, iron columns connected with the yokes at the top and the bottom and windings winding round the iron columns, wherein the iron columns are moulded by cohering iron powder and adhesive. The iron powder and the adhesive are mixed together evenly, therefore, superfine nonmagnetic clearances are generated among the iron powder, and thus the defects that a common silicon-steel plate iron core element has larger iron core eddy-current loss under high frequency and is easy to generate noise under the magnetostrictive action are overcome.
Description
Technical field
The utility model relates to field of electrical equipment, relates in particular to a kind of filter reactor.
Background technology
Filter reactor is an important devices in the power filter device, by filter reactor, filtering capacitor accurately tuning can make high order frequency harmonics current absorption in the power network to filter, thereby reach the purification electrical network, improve the purpose of the quality of power supply.
At present, existing filter reactor technology mainly contains two kinds of air core reactor and laminated core reactors.It is good that air core reactor has the linearity, transfers sense convenient, the advantage that running noises is little; but it is big that weak point is a small product size, and surrounding environment is produced electromagnetic interference, can not be installed in the cabinet; need bigger fabricating yard and must be, sensitive equipments such as relaying protection facility away from computer.
Though it is big that the laminated core reactor has overcome volume, can not be installed in the cabinet and the shortcoming of electromagnetic interference, but its employing unshakable in one's determination is normal lamination formula silicon steel sheet, this iron core can only move under work frequency, when the high-frequency harmonic electric current flows through, significantly heating unshakable in one's determination, and send very big high-frequency noise.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of low noise filter reactor.
In order to solve the problems of the technologies described above, the utility model provides a kind of filter reactor, comprise being positioned at the described iron prop of the iron yoke of both sides up and down of iron yoke, connection of both sides up and down, and the winding that twines described iron prop, described iron prop is adhesion-molded by adhesive by iron powder.
Wherein, described iron yoke is also adhesion-molded by adhesive by iron powder.
Wherein, described iron powder is the above iron powders of 200 orders; And described adhesive is an organic bond.
In addition, the two ends of described iron prop and middle part are provided with insulation material layer.
Wherein, the permeability of described insulation material layer is consistent with the permeability of air.
In the utility model, because binding agent is evenly mixed with iron powder, thereby many ultra-fine non-magnetic gaps just between iron powder, have been produced, so just overcome ordinary silicon steel disc ferromagnetic element eddy current loss unshakable in one's determination under high frequency and increased, and under the magnetostriction effect, be easy to generate the shortcoming of noise.
In addition, the utility model has overcome that the small product size that air core reactor utilizes space outerpace to exist as magnetic conductive loop is big, electromagnetic interference seriously, particularly can not be installed on the shortcoming in the cabinet owing to had unshakable in one's determinationly as magnetic conductive loop.
Magnetic of the present utility model is unshakable in one's determination, and organic material evenly mixes with iron powder owing to adopt the organic material molding bonded, the possibility that the iron core after the moulding is not got rusty, and the while organic material greatly reduces eddy current loss as the insulating barrier between iron powder.
Description of drawings
Fig. 1 is the profile of an embodiment of a kind of filter reactor of the utility model.
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing.
With reference to figure 1, illustrate the profile of an embodiment of a kind of filter reactor of the utility model.As shown in the figure, be shown as a three-phase filter reactor in the present embodiment, it comprises and is positioned at the up and down iron yoke 3 of both sides, and is arranged on the iron core 2 between the iron yoke 3 of described both sides up and down, comprises three iron cores in the present embodiment altogether; Also comprise, twine the winding 1 of described iron core.
Importantly, described iron yoke 3 and unshakable in one's determination 2 is by iron powder more than 200 orders and organic bond mixed-forming.
And, described unshakable in one's determination 2 middle part and up and down two ends be provided with insulation material layer 4, the permeability of the material that this insulation material layer adopted is consistent with the permeability of air, so the thickness of insulation material layer 4 just is equivalent to air gap thickness, can regulate the inductance of reactor easily by regulating air gap thickness.
In the utility model, because binding agent is evenly mixed with iron powder, thereby many ultra-fine non-magnetic gaps just between iron powder, have been produced, so just overcome ordinary silicon steel disc ferromagnetic element eddy current loss unshakable in one's determination under high frequency and increased, and under the magnetostriction effect, be easy to generate the shortcoming of noise.
In addition, the utility model has overcome that the small product size that air core reactor utilizes space outerpace to exist as magnetic conductive loop is big, electromagnetic interference seriously, particularly can not be installed on the shortcoming in the cabinet owing to had unshakable in one's determinationly as magnetic conductive loop.
Magnetic of the present utility model is unshakable in one's determination, and organic material evenly mixes with iron powder owing to adopt the organic material molding bonded, the possibility that the iron core after the moulding is not got rusty, and the while organic material greatly reduces eddy current loss as the insulating barrier between iron powder.
Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
