Abstract
The utility model relates to a paperless bundled transposition wire, which comprises two lines of enameled wire groups, lining paper, a transposition wire and a grid belt, wherein the lining paper is arranged between the two lines of enameled wire groups; the transposition wire is arranged in a central position at the upper part of the two lines of enameled wire groups; and the grid belt is bundled and encompassed on the two lines of enameled wire groups and the transposition wire. The paperless bundled transposition wire provided by the utility model is not provided with an insulation layer encompassing outside thereof, but only provided with a grid belt layer bundled outside thereof, thereby decreasing the volume of the transposition wire and further that of a transformer, and the grid enhances the heat dissipation capability of the wire.
Description
[technical field]
The utility model relates to a kind of transposed conductor of Transformer Winding coil, is specifically related to a kind of no paper cluster transposed conductor, belongs to the winding wire technical field.
[background technology]
Single bag paper covered wire and composite conductor are as the history in existing more than 100 year of winding of transformer, because its production process is simple, with low content of technology, cheap, the vitality on market continues into the present always.But, along with the continuous development of electric utility, the requirement of power transmission and distribution is also improved constantly, progressively the direction to superhigh pressure, high-power transformer develops; Not only the coil windings to transformer has proposed the loss of reduction circulating current, reduced volume, reduce operating temperature, reduce the requirement of electromagnetic consumable, also require transformer to have stronger Short Circuit withstand burst capability, under this condition, transposed conductor produces immediately, the broken hair exhibition is imperfect, has derived series such as self-adhering transposed conductor, semihard self-adhering transposed conductor, no paper insulation cluster transposed conductor.Transposed conductor is compared with other winding materials such as paper covered wire, and following advantage is arranged:
(1) can dwindle the barred window size, increase copper factor, thereby can dwindle machine volume, saving materials;
(2) in the transformer manufacture process also because coiling is convenient can reduce cost greatly and reduce the probability that quality problems occur;
(3) transformer has increased economic benefit and social benefit owing to having reduced eddy current loss and circulating current loss again greatly in running.
At present, along with the capacity increase of transformer, heavy in section transposed conductor has obtained great use, and the caloric value of coil rises gradually, and heat dispersion is not good, has improved the temperature of transformer, has reduced its useful life.These problems have caused transformer often because of the excess load heating causes fault, cause transformer to reduce useful life, and volume of transformer increases, and cost improves.
For avoiding above-mentioned technical problem, the necessary paper bag lead that a kind of advanced person is provided is to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of no paper cluster transposed conductor that does not have outsourcing insulation, and it can dwindle the transposed conductor volume, has also improved the lead heat-sinking capability.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of no paper cluster transposed conductor, it comprises two row enamelled wire groups, lining paper between two row enamelled wire groups and a transposition line that is arranged at two row enamelled wire group top center positions, bundle is covered with the grid belt on described two row enamelled wire groups and transposition line.
No paper cluster transposed conductor of the present utility model also can be set to: every row enamelled wire group is piled up by 4 enamelled wires and is formed.
No paper cluster transposed conductor of the present utility model also can be set to: the insulation enamelled coating that described enamelled wire comprises a copper strap wire and is coated on the copper strap wire outer surface.
Compared with prior art, the utlity model has following beneficial effect: no paper cluster transposed conductor of the present utility model does not have outsourcing insulation and only bundlees a grid band, so both can dwindle the transposed conductor volume, simultaneously, grid has also improved the lead heat-sinking capability; In addition, lining paper is set between the two row enamelled wires makes the wires carry electric current big, and can reduce eddy current loss, turn-to-turn insulation is reliable.
[description of drawings]
Fig. 1 is the structural representation of no paper cluster transposed conductor of the present utility model.
Fig. 2 is the structural representation of enamelled wire of the present utility model.
[embodiment]
See also Figure 1 and Figure 2, the utility model is a kind of transposed conductor, it comprises two row enamelled wire groups 1, lining paper 2 between two row enamelled wire groups 1, and a transposition line 3 that is arranged at two row enamelled wire groups, 1 top center position, bundle is covered with grid belt 4 on described two row enamelled wire groups 1 and transposition line 3.Wherein, every row enamelled wire group is piled up by 4 enamelled wires and is formed the insulation enamelled coating 111 (as shown in Figure 2) that each enamelled wire 11 comprises a copper strap wire 110 and is coated on copper strap wire 110 outer surfaces.Described insulation enamelled coating 111 is an acetal paint, and its thickness is 0.11～0.16mm.The thickness of described grid belt is generally 0.56mm (individual layer is the thick grid band of 0.28mm, overlapping wrapped thickness can greater than 2mm).Described lining paper 2 can be Leshan DLZ-130 cable paper tape.For avoiding the mechanical wear of grid belt 4 in transportation, Leshan DLZ-130 cable paper tape of outside grid belt 4, can double-baging again (gap is wrapped, and the gap is generally at 3～4mm, evenly staggers in two lamellar spacings) (not shown).
Because described grid belt 4 need be discarded when the user winds the line, before binding grid band 4, can put a fishnet line 5 along transposition line 3 trends, tear grid belt 4 discarded to make things convenient for the user.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection range of this creation.
