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 a kind of Transformer Winding cooling field, particularly a kind of big capacity distribution transformer and rectifier transformer that contains the axial double-oil-passage winding.
Background technology
Distribution transformer heap(ed) capacity by national standard 10kV, 35kV is 1600kVA, and axial single oil duct routinely just can solve the problem of temperature rise of winding.Along with the demand of market to big capacity distribution transformer and rectifier transformer, axial single oil duct can't resolve the temperature rise of winding, if want the requirement of temperature rise conformance with standard, will increase raw material exactly nothing but, increases cost, the 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, with the area of dissipation of raising winding, thereby improve the radiating effect of winding inside, on the Acer plinth of former axial single oil duct, can increase by about 40% area of dissipation, economical with materials reduces cost.
The technical scheme that solution the technology of the present invention problem is adopted is: a kind of transformer that contains the axial double-oil-passage spiral winding, one insulating cylinder, three spaces and the spiral winding that is provided with around insulating cylinder, two-layer at least cushion block separates above-mentioned winding to form axial double-oil-passage.
On the basis of technique scheme, further comprise the other technologies scheme:
It further comprises the insulating end ring that is used for fixing cushion block;
Described cushion block comprises end cushion block and middle cushion block;
The protuberance of several spaces that described cushion block outwards protrudes by a substrate with by this substrate constitutes;
Described substrate is a quadrangle;
Described substrate is hypotenuse on one side, and its excess-three limit is a straight flange.
The invention has the beneficial effects as follows: can increase by about 40% area of dissipation on the basis of former axial single oil duct, the radiating effect of winding inside is preferable, and economical with materials reduces cost, and has strengthened spiral winding mechanical strength by insulating end ring.

Among the figure: 1. insulating cylinder, 2. winding, 3. cushion block, 4. insulating end ring, 5. oil duct, cushion blocks in the middle of 30., 31. end cushion blocks, 300. substrates, 302. protuberances.
Embodiment
Shown in Fig. 1-4, the transformer that contains axial double-oil-passage of the present invention, it comprises that an insulating cylinder 1, three spaces and the winding 2 that is provided with around insulating cylinder, at least two cushion blocks 3 separate above-mentioned winding to form the axial double-oil-passage and the fixing insulating end ring 4 of cushion block 3.Wherein cushion block 3 comprises end cushion block (or claim taper liner piece) 31 and middle cushion block 30, and the protuberance 302 of several spaces that cushion block 3 structures are outwards protruded by a substrate 300 with by this substrate 300 constitutes.And end cushion block 31 is because the similar shape in the shape of a spiral of winding, and two ends all are oblique reason, and substrate 300 is a quadrangle, Yi Bian wherein be the hypotenuse shape, its excess-three limit is a straight flange, and the substrate 300 of middle cushion block 30 is then rectangular.
Because the winding two ends all are oblique, end cushion block 31 is adopted at two ends, and cushion block 30 in the middle of middle the 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 the placement is promptly placed two-layer cushion block, thereby formed axial double-oil-passage 5.Insulating end ring 4 is used for fixing end cushion block 31 and has strengthened spiral winding 2, prevents that cushion block from coming off and strengthened the mechanical strength of winding 2.
In sum, technical scheme of the present invention can increase by about 40% area of dissipation on the basis of former axial single oil duct, and the radiating effect of winding inside is preferable, and economical with materials reduces cost, and especially is fit to big capacity distribution transformer and rectifier transformer.
Though the present invention with preferred embodiment openly as above; but it is not in order to qualification 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, so protection scope of the present invention should be with being as the criterion that claims were defined.
