Abstract
The invention provides a transformer containing axial double-oil-passage spiral windings, comprises an insulating barrel, three mutually spaced spiral windings arranged around the insulating barrel and at least two layers of cushion blocks for dividing the windings to double axial oil passages. By adopting the technical scheme, the heat radiating effect in the windings can be improved, and 40 percent of heat radiating area can be increased on the basis of an original axial single oil passage; and the transformer has the advantages of material saving and cost reduction and is particularly suitable for high-capacity distribution transformers.
Description
Technical field
The present invention relates to the cooling field of a kind of Transformer Winding, particularly a kind of large capacity of power distribution transformer and rectifier transformer that contains axial double-oil-passage winding.
Background technology
Be 1600kVA by the distribution transformer heap(ed) capacity of national standard 10kV, 35kV, axial single oil duct routinely just can solve the problem of temperature rise of winding.Along with the demand of market to large capacity of power distribution transformer and rectifier transformer, axial single oil duct can't resolve the temperature rise of winding, if want temperature rise to meet standard-required, will increase exactly nothing but raw material, increases cost, waste resource.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of low-voltage and high-current axial double-oil-passage spiral winding, to improve the area of dissipation of winding, thereby improve the radiating effect of winding inside, on the Acer plinth of former axial single oil duct, can increase by approximately 40% area of dissipation, save material, reduce costs.
The technical scheme that solution the technology of the present invention problem adopts is: a kind of transformer that contains axial double-oil-passage spiral winding, one insulating cylinder, three spaces and the Helical winding arranging around insulating cylinder, at least two-layer cushion block separates to form axial double-oil-passage by above-mentioned winding.
On the basis of technique scheme, further comprise other technologies scheme:
It further comprises the insulating end ring for fixing cushion block;
Described cushion block comprises end cushion block and middle cushion block;
Described cushion block forms by a substrate with by the protuberance of several outwardly spaces of this substrate;
Described substrate is quadrangle;
Described substrate is hypotenuse on one side, and its excess-three limit is straight flange.
The invention has the beneficial effects as follows: on the basis of former axial single oil duct, can increase by approximately 40% area of dissipation, the radiating effect of winding inside is better, save material, reduce costs, strengthened Helical winding mechanical strength by insulating end ring.

In figure: 1. insulating cylinder, 2. winding, 3. cushion block, 4. insulating end ring, 5. oil duct, 30. middle cushion blocks, 31. end cushion blocks, 300. substrates, 302. protuberances.
Embodiment
As Figure 1-4, the transformer that contains axial double-oil-passage of the present invention, it comprises an insulating cylinder 1, three spaces and around the winding 2 of insulating cylinder setting, the insulating end ring 4 that at least two cushion blocks 3 are separated above-mentioned winding to form axial double-oil-passage and fixing cushion block 3.Wherein cushion block 3 comprises end cushion block (or claiming taper liner piece) 31 and middle cushion block 30, and cushion block 3 structures form by a substrate 300 with by the protuberance 302 of several outwardly spaces of this substrate 300.And end cushion block 31 is because winding is in the shape of a spiral similar, two ends are all oblique reason, and substrate 300 is quadrangle, are wherein hypotenuse shape on one side, and its excess-three limit is straight flange, and the substrate 300 of middle cushion block 30 is rectangular.
Because winding two ends are all oblique, employing end, two ends cushion block 31, and cushion block 30 in the middle of middle employing.Form an oil duct 5 by end cushion block 31 and middle cushion block 30, interior outer oil sump end face is all placed end cushion block 31, and cushion block 30 in the middle of middle placement is placed two-layer cushion block, thereby formed axial double-oil-passage 5.Insulating end ring 4 is for anchor portion cushion block 31 and strengthened Helical winding 2, prevents that cushion block from coming off and having strengthened the mechanical strength of winding 2.
In sum, technical scheme of the present invention can increase by approximately 40% area of dissipation on the basis of former axial single oil duct, and the radiating effect of winding inside is better, saves material, reduces costs, and is especially applicable to large capacity of power distribution transformer and rectifier transformer.
Although the present invention with preferred embodiment openly as above; but it is not in order to limit the present invention, any person skilled in the art, without departing from the spirit and scope of the present invention; all can do various changes and modification, therefore protection scope of the present invention should be with being as the criterion that claims were defined.
