Abstract
The invention relates to a plurality of transposed conductor and belongs to the technical field of conductor processing. The transposed conductors are formed by first dividing a plurality of enameled rectangular section conductors into two rows and by bundling the two rows of enameled rectangular section conductors after twisting transposition. The conductors are characterized in that: the plurality of enameled rectangular section conductors are divided into two rows with the narrow sides contacted with each other; a heat-resistant lining is lined between two rows of which the narrow sides are against each other; a bundle of conductors is formed by twisting transposition; a high-temperature insulated layer is integrated with the bundle of conductors as a whole by being wound outside the bundle of conductors; and the plurality of transposed conductors is obtained by winding the given meters of conductors after a traction device is compressed on the conductors. The conductors have the advantages of simple, compact and reasonable structure, high conductive and radiating efficiencies, convenient coil winding and capability of being applied to a big motor to substitute a large-size copper bar.
Description
Technical field
The present invention relates to a kind of plurality of transposed conductors, specifically be divided into two identical row of radical, form, belong to the lead processing technique field through boundling behind the transposition by twisting by even number root enameled sheet wire.
Background technology
At present, the winding that uses transposed conductor to make large oil immersed power transformer, reactor and big capacity dry-type transformer has become a kind of trend, adopt winding transposition wire work to be easier to, the electrical efficiency height, it is little that coil accounts for volume, and, reduce eddy current loss because each single enameled sheet wire total length in the transposition process is consistent.Present domestic transposed conductor kind development rapidly, the structure of transposed conductor and size basic forming adopt different insulation systems according to the difference of service condition, but the lead radical that adopts are the odd number root, can adopt more convenient mode when replacing like this.Relatively distinct issues are arranged in the transformer repair procedures, exactly after former Transformer Winding is repaired or is changed once more equipment advance transformer to run into size bigger than normal, processing mode one is that ampacity is reduced to change little conductor size, the reduction transformer efficiency; The 2nd, reduce core dimensions, the magnetic circuit loss is bigger like this, and transformer is overheated easily, the life-span instability.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of plurality of transposed conductors is provided, can be applicable to replace large size copper row among the big motor, the coil of coiling is convenient, can improve conduction and radiating efficiency.
According to technical scheme provided by the invention, plurality of transposed conductors comprises enameled sheet wire, temperature-resistant insulation layer and heat-resisting lining thing, feature is: two row that become narrow limit to be in contact with one another by the assortment of even number root enameled sheet wire, lining is with heat-resisting lining thing in the middle of two row that lean on mutually on narrow limit, form whole bunch through transposition by twisting, outside whole bunch, twine temperature-resistant insulation layer and form one, through coil on after the pulling equipment compacting around regulation rice number plurality of transposed conductors.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Conduction and radiating efficiency height, the coil of coiling is convenient, can be applicable to replace large size copper row among the big motor.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 5: comprise first enameled sheet wire 1, second enameled sheet wire 2, the 3rd enameled sheet wire 3, the 4th enameled sheet wire 4, the 5th enameled sheet wire 5, the 6th enameled sheet wire 6, the 7th enameled sheet wire 7, the 8th enameled sheet wire 8, copper strap wire conductor 9, acetal insulating barrier 10, temperature-resistant insulation layer 11 and heat-resisting lining thing 12.
Plurality of transposed conductors radical of the present invention can be chosen between 4～80 radicals, and choosing transposed conductor in the embodiment of the invention is 8 enameled sheet wires, and described enameled sheet wire is made up of copper strap wire conductor 9 and acetal insulating barrier 10.The described copper strap wire conductor 9 outer insulation enamelled coatings 10 that apply form enameled sheet wire.Described copper strap wire conductor and insulation also can be other structures such as other metal materials and fiber, paper, film etc.
The present invention is arranged in two identical row of radical respectively with first enameled sheet wire 1, second enameled sheet wire 2, the 3rd enameled sheet wire 3, the 4th enameled sheet wire 4, the 5th enameled sheet wire 5, the 6th enameled sheet wire 6, the 7th enameled sheet wire 7, the 8th enameled sheet wire 8, and lining is with heat-resisting lining thing 12 in the middle of two row that narrow limit is leaned on mutually.
As shown in Figure 2: with about two row enameled sheet wires press down respectively and go up the top position that line is thick, reserve the transposition space;
As shown in Figure 3: with about two outstanding distortion of making the contraposition direction respectively of two row enameled sheet wires, deformed shape is " S " type;
As shown in Figure 4: with about two row enameled sheet wires outstanding two push up and press down a thick position of line on respectively, make it reply the home position, but variation has taken place in the position of lead.
Above-mentioned 8 enameled sheet wires are formed the Bundling conducting wire core through transposition by twisting to a corresponding row boundling.Outside the Bundling conducting wire core, twine temperature-resistant insulation layer 11 and form one, through coil on after the pulling equipment compacting around regulation rice number plurality of transposed conductors.
Claims (2)
1. plurality of transposed conductors, comprise enameled sheet wire, temperature-resistant insulation layer (11) and heat-resisting lining thing (12), it is characterized in that: two row that become narrow limit to be in contact with one another by the assortment of even number root enameled sheet wire, lining is with heat-resisting lining thing (12) in the middle of two row that lean on mutually on narrow limit, form whole bunch through transposition by twisting, outside whole bunch, twine temperature-resistant insulation layer (11) and form one, behind overcompaction plurality of transposed conductors.
2. plurality of transposed conductors according to claim 1 is characterized in that described even number root enameled sheet wire is between 4～80 radicals.
