Abstract
The utility model relates to a spiral winding transformer which comprises a strut component and is characterized in that: a spiral winding is wound on the strut component; the spiral winding is composed of at least three rows of leads in parallel connection; and spacing components are arranged between the leads. Thus, the size of the leads can be more reasonably and flexibly selected and the application scope of the spiral winding is further widened. Besides, in a certain current scope, the defect of inferior winding manufacturability caused by oversize or undersize width of a traditional single double-spiral or four-spiral lead is overcome. To some extent, the winding efficiency is increased, so that the selection for the size of the leads is more reasonable and flexible, the eddy-current loss is effectively reduced and the electric energy is saved.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of spiral winding transformer.
Background technology
Along with the continuous development of national economy and modern industry, also increasingly high to the requirement of electric power system, like the increase of radius of electricity supply, increase of transformer capacity or the like.And the increase of transformer capacity, that is be will increasing of transformer current, that is to say that the structural shape of Transformer Winding will have basic change.Therefore a kind of " triple helical " formula winding between double helix and four spirals arises at the historic moment.
And; Along with the increase of transformer capacity,, occurred adopting traditional double helix or four spiral windings to have following shortcoming: if adopt double helix for low pressure winding, the pressure regulation winding of big electric current; Then the width of solid conductor is excessive; And adopt four spirals, and then the width of solid conductor is too small again, and winding process is poor.
The utility model content
The purpose of the utility model is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of spiral winding transformer is provided.
The purpose of the utility model realizes through following technical scheme:
Spiral winding transformer includes the stay assembly, and wherein: be wound with spiral line group on the described stay assembly, described spiral line group has at least the parallel connection of three column wires to constitute, and is provided with distance member between the described lead.
Further, above-mentioned spiral winding transformer, wherein: described stay assembly two ends up and down is provided with the end circle.
Again further, above-mentioned spiral winding transformer, wherein: described distance member is a cross-over block.
The advantage of the utility model technical scheme is mainly reflected in: can select wire gauge more rationally, flexibly, make the range of application of spiral winding further widen.And, in certain current range, overcome the shortcoming of the excessive or too small winding process difference of bringing of traditional double spiral or four spiral solid conductor width.Simultaneously, improve coiling efficient to a certain extent, made in the selection of wire gauge to have effectively reduced eddy current loss more rationally, flexibly, saved electric energy.
Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using the utility model technical scheme, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.
Fig. 1 is the organigram of spiral winding transformer.
Embodiment
Spiral winding transformer as shown in Figure 1 includes stay assembly 1, and its unusual part is: be wound with spiral line group on the stay assembly 1 that the utility model adopted.Specifically, in order to satisfy the structure needs of triple helical formula, satisfy the transition between double helix and four spirals, spiral line group has at least 2 parallel connections of three column wires to constitute.And, be provided with distance member between the lead 2.
With regard to the utility model one preferred implementation, consider that to prevent that lead 2 from occurring in winding process axial at random, influence the whole result of use of transformer, two ends be provided with end circle 3 at the stay assembly about in the of 1.
Further, consider different results of use, the radial parallelly connected radical of the lead 2 that the utility model adopted is at least two.Like this, according to the difference of lead 2 parallelly connected radicals, can effectively adjust the size of radius of electricity supply and transformer capacity.
Again further, in order effectively to insulate, improving the job stability of spiral line group, is cross-over block 4 at distance member.
In conjunction with the actual operating position of the utility model, in order to reduce circulation, to make the residing stray field of different conductor position approximate identical, must replace, its transposition has its particularity, by different parallelly connected situation, is divided into following several kinds:
1, three column wires parallel connection radical is inequality; Few one of middle column when the parallel conducting wire radical is even number, adopts evenly transposition; Transposition number is 2 times of parallel conducting wire radical, and evenly the process of transposition is: (1) first a row topmost lead are changed to secondary series topmost; (2) the bottom lead of secondary series is changed to the first row bottom; (3) the 3rd a row topmost lead are changed to secondary series topmost; (4) the bottom lead of secondary series is changed to the 3rd row bottom; (5) repeating (1)～(4) step gets final product.
2, three column wires parallel connection radical is inequality, and few one of middle column when the parallel conducting wire radical is odd number, adopts evenly transposition (method is the same), and transposition number is 4 times of parallel conducting wire radical.
3, three column wires parallel connection radical is identical, when the parallel conducting wire radical is even number, adopts even coordinated transposition.Transposition number is identical with the parallel conducting wire radical, and evenly the process of coordinated transposition is: (1) first a row topmost lead are changed to secondary series topmost, and it is bottom that first row are changed in one of secondary series bottom; (2) the 3rd a row topmost lead are changed to secondary series topmost, and it is bottom that the 3rd row are changed in one of secondary series bottom; (3) repeating (1)～(2) step gets final product.
4, three column wires parallel connection radical is identical, when the parallel conducting wire radical is odd number, adopts even coordinated transposition (method is the same), and transposition number is 2 times of parallel conducting wire radical.
Can find out through above-mentioned character express, behind employing the utility model, can select wire gauge more rationally, flexibly, make the range of application of spiral winding further widen.And, in certain current range, overcome the shortcoming of the excessive or too small winding process difference of bringing of traditional double spiral or four spiral solid conductor width.Simultaneously, improve coiling efficient to a certain extent, made in the selection of wire gauge to have effectively reduced eddy current loss more rationally, flexibly, saved electric energy.
