Abstract
The utility model relates to a winding, in particular to a winding in which the cross section of enameled wires is elliptical, quadrangular or strip-shaped. The winding comprises the enameled wires, and each enameled wire comprises an insulating layer and a metallic conductor with the insulating layer uniformly formed thereon. Since the cross section of the enameled wires is elliptical, quadrangular or strip-shaped, the enameled wires can be combined tightly, further, the utilization ratio of an iron core window is improved, the winding volume is reduced, the material consumption is lowered, the cost and noise generated by the product are lowered. The utility model also provides a transformer and a reactor both employing the winding.
Description
Technical field
The utility model has related to a kind of winding, is the winding of cross section ovalize, quadrangle or the strip of enamelled wire specifically;

The purpose of the utility model is: a kind of winding is provided; Be the winding of enamelled wire cross section ovalize, quadrangle or strip specifically; The winding that the enamelled wire of this structure constitutes can reduce the space between the enamelled wire, makes the enamelled wire contact area increase, and is more firm;
A kind of transformer and reactor that is provided with above-mentioned winding also is provided.
For addressing the above problem; The technical scheme that the utility model adopts is: a kind of winding, to form by enamelled wire, and enamelled wire is made up of insulating barrier and metallic conductor; Insulating barrier evenly covers on the metallic conductor, cross section ovalize, quadrangle or the strip of said enamelled wire;
Said quadrangle is the quadrangle through chamfering
Said quadrangle is a square;
The composition material of said metallic conductor is that copper material, aluminium, copper cover aluminum, copper electroplating nickel on surface or copper surface electrical are zinc-plated;
Said insulating barrier is insulation paint film or insulating paper;
A kind of transformer that said winding is set, said winding is made up of enamelled wire, and enamelled wire is made up of insulating barrier and metallic conductor, and insulating barrier evenly covers on the metallic conductor, cross section ovalize, quadrangle or the strip of said enamelled wire;
Said quadrangle is the quadrangle through chamfering;
A kind of reactor that said winding is set, said winding is made up of enamelled wire, and enamelled wire is made up of insulating barrier and metallic conductor, and insulating barrier evenly covers on the metallic conductor, cross section ovalize, quadrangle or the strip of said enamelled wire;

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Embodiment one:
Like Fig. 2,3 said, the said winding of the utility model is made up of enamelled wire 1, and the cross section of enamelled wire 1 is square, like this, by the winding that its coiling forms, can effectively reduce the gap that forms between the enamelled wire 1.Enamelled wire 1 comprises insulating barrier 2 and metallic conductor 3, and insulating barrier 2 evenly covers metallic conductor 3 surfaces.Wherein, insulating barrier 2 is to be processed by the insulation paint film, and metallic conductor 3 is made up of copper material or aluminium.
The winding of this structure is owing to enamelled wire 1 can be combined closely, so reduced the volume of winding; Reduce consumptive material, practice thrift cost, improved the core window utilance simultaneously; Increase the contact area between the enamelled wire 1 in addition, made the noise that produces because of electromagnetic induction effectively reduce.
Also relate to a kind of transformer, transformer is provided with above-mentioned winding, reduces winding volume, reduces consumptive material, practices thrift cost, makes the transformer operating efficiency improve, and has reduced noise.
Also relate to a kind of reactor, reactor is provided with above-mentioned winding, reduces winding volume, reduces consumptive material, practices thrift cost, makes the reactor operating efficiency improve, and has reduced noise.
Embodiment two:
As shown in Figure 4, to compare with embodiment one, the difference of present embodiment is that the cross section of enamelled wire 1 is the rectangle through rounding.Simultaneously, insulating barrier 2 is to be processed by insulating paper, and metallic conductor 3 is copper cover aluminum structures.The same effect that realizes embodiment one.
Embodiment three:
As shown in Figure 5, to compare with the foregoing description, the difference of present embodiment is that the cross section of enamelled wire 1 is elongated, just enamelled wire 1 is processed to band shape, the more effective like this gap that has reduced between the enamelled wire 1.Simultaneously, metallic conductor 3 is copper electroplating nickel on surface, realizes above-mentioned effect equally.
Embodiment four:
As shown in Figure 6, to compare with the foregoing description, the difference of present embodiment is, the cross section ovalize of enamelled wire 1 makes that so equally the space between the enamelled wire 1 reduces, and has increased the contact area between the enamelled wire 1.Metallic conductor 3 is that the copper surface electrical is zinc-plated.The same better effects that realizes.
