Abstract
The utility model discloses a transformer grade foil coil with simple winding process, short cycle and excellent local discharge performance, which includes a plurality of windings; the upper end of each winding is provided with an upper ex-terminal, and the lower end of the winding is provided with a lower ex-terminal; the windings are connected end to end with each other by the upper and the lower ex-terminals; the windings consist of a plurality of loops of conductive foil layers and insulating foil layers; one insulating foil layer is arranged between every two conductive foil layers. The local discharge performance is below 5PC or even 0PC.
Description
Technical field
The utility model relates to the transformer coil field, particularly the transformer foil coil.
Background technology
At present, the loop construction of transformer has two kinds of forms, and the one, segmented layered, the 2nd, the continuous cake formula of segmentation structure.These two kinds of structures are copper cash or aluminum steel winding structure.Adopt the transformer of these two kinds of loop construction forms, technology more complicated in winding process not only, the coiling cycle is long, make mistakes easily, and winding process is also very high to workman's technical skills requirement, and the coil that coiling goes out neither be very low on the partial discharge performance, generally at 5～20PC.
Summary of the invention
The utility model has been mainly segmented transformer coil winding complex process in the solution prior art, and the coiling cycle is long, the imperfect shortcoming of partial discharge performance.
The utility model provides a kind of technique for coiling simple, cycle weak point and the transformer segmentation foil coil with good partial discharge performance.
The utility model is achieved through the following technical solutions: a kind of transformer segmentation foil coil, comprise some windings, in the upper end of winding terminal on is arranged, in the lower end of winding following terminal is arranged, winding joins end to end by last terminal and following terminal and remaining winding and connects, winding is made up of the conductor foil layer and the insulation paper tinsel layer of some circles, is insulation paper tinsel layer between the two conductor foil layers.
Above-mentioned insulation paper tinsel layer is made up of 1～2 layer of insulation paper tinsel, and wherein conductor foil can be selected Copper Foil or aluminium foil for use.
After adopting the technical solution of the utility model,, assemble again after coiling is good because each winding is coiling respectively, operation is simple relatively in the winding process of the transformer coil that makes, the coiling cycle has shortened greatly, and can coiling on the automation equipment of higher degree, is difficult for makeing mistakes.Skilled worker's technical ability is required also lower, the coil that coiling goes out reaches more excellent on the partial discharge performance, below 5PC even 0PC.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described:
Fig. 1 is the front view of transformer segmentation foil coil.
Fig. 2 is the vertical view of transformer segmentation foil coil.
Among the figure: 1. 5. times terminals of terminal on the winding 2. insulation paper tinsel layers 3. conductor foil layer 4.
Embodiment
A kind of transformer segmentation foil coil, comprise some windings 1, terminal 4 on one is arranged in the upper end of winding 1, in the lower end of winding 1 following terminal 5 is arranged, winding 1 joins end to end by last terminal 4 and following terminal 5 and remaining winding and connects, winding 1 is made up of the conductor foil layer 3 and the insulation paper tinsel layer 2 of some circles, is insulation paper tinsel layer 2 between the two conductor foil layers 3.
Each winding 1 is need carry out coiling wrapping on the mould of insulating material by producing, during coiling with one or two-layer insulation paper tinsel and one deck conductor foil about align, the insulation paper tinsel place conductor foil below, paper tinsel layer and the conductor foil ply coiling from inside to outside of getting up together of will insulating, arrive the number of turn of setting when coiling after, cut off the blended rubber band fix terminal, wrap insulating barrier again at skin.After the good remaining winding of same method coiling, successively the last terminal of winding 1 and the following terminal of last winding are joined with copper sheathing, following terminal is connected with copper sheathing with the last terminal of back one winding.Whole connect the back a segmentation foil coil, this coil on the partial discharge performance below 5PC even 0PC.
Here description of the present utility model and application are illustrative, are not to want with scope restriction of the present utility model in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the actual replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present utility model or substantive characteristics, and the utility model can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.Under the situation that does not break away from the scope of the invention and spirit, can carry out other distortion and change here to disclosed embodiment.
Claims (3)
