Abstract
The utility model discloses a transformer coil structure. Segmented cylinder-type coils of a dry-type transformer are in an inter-section inclined-pull type structure or an inter-layer inclined-pull type structure. The inter-section inclined-pull type structure is as follows: the coiling is started from the first layer of a section; according to the traditional cylinder-type coil coiling method, after the coiling of the last layer is completed, the tail head is not cut off but directly passes through an inter-section insulator to be pulled in inclination to be coiled at the first layer position of the next section to be coiled. The inter-layer inclined-pull type structure is as following: the coiling is started from the first layer of a section, for example, the coiling is started from bottom to top; after the coiling of the first layer is completed, the wire is pulled in inclination to the lower end of the second layer and continuously coiled from bottom to top; all layers are coiled in the same way; and then the tail head is cut off to prepare for the coiling of the next section. The transformer coil structure has the advantages of reducing the cost of the transformer and improving the insulating performance of the transformer.
Description
Technical field:
The utility model design relates to technical field of transformer manufacturing, the improvement of the winding structure of concrete dry-type transformer coil.
Background technology:
At present, dry-type transformer has obtained using widely.But the dry-type transformer winding is exposed in the air, has lacked the insulating protection of transformer oil, and for guaranteeing the insulation property of transformer, then the each several part electric field strength to winding has strict restriction.Should control the electric field strength of winding each several part, not increase the transformer cost again.According to formula " electric field strength=voltage/distance ", then we must reduce the voltage difference of winding each several part.
The utility model content:
The utility model technical problem to be solved just provides the transformer coil with new structure; Reduce the voltage difference of dry-type transformer coil each several part; So just can guarantee to reduce the insulation distance of each several part under the certain situation of electric field strength, thereby reach the purpose that reduces the transformer cost; Or under the immovable situation of insulation distance, reduce electric field strength, thereby strengthen the insulation property of transformer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Transformer coil structure is intersegmental slant-pull structure or interlayer slant-pull structure at dry-type transformer subsection cylindrical formula coil.
Said intersegmental slant-pull structure for from a certain section ground floor around; According to traditional round cartridge type coil winding method, after the last one deck of coiling was accomplished, the tail head did not cut off; Directly pass section insulation, tiltedly move to will coiling next section first floor position begin the structure that coiling forms.
Said interlayer oblique roller for from a certain section ground floor around, for example coiling from bottom to top, after the ground floor coiling is accomplished; Lead tiltedly is pulled to second layer lower end; Continue coiling from bottom to top, and by this way, all numbers of plies are accomplished in coiling; Then the tail head is cut off, prepare the structure that the coiling of next section forms.
The good effect of the utility model is; (1) oblique roller can make that the more common subsection cylindrical formula of voltage difference coil reduces by one times between adjacent two intersegmental largest segment; So just can reduce the hop count of subsection cylindrical formula coil or reduce the section insulation distance, reduce the transformer cost.(2) oblique roller can reduce by one times with the maximum voltage between layers between adjacent two layers, so just can reduce the number of plies of graded winding or reduce layer insulation thickness, to reduce the transformer cost.
Description of drawings:
Fig. 1, the intersegmental oblique roller figure of the utility model dry-type transformer coil.
Fig. 2, the utility model dry-type transformer coil interlayer oblique roller figure.
Embodiment:
As shown in Figure 1 during intersegmental slant-pull structure coiling, coiling is second section in proper order, first section, and the 3rd section, the 4th section.At first according to second section of conventional cylindrical layer winding winding method coiling; After the last one deck of, coiling is accomplished, the tail head is passed section insulation from ground floor; Tiltedly move first section first floor position to and begin first section coil of coiling, the tail head promptly can be used as lifting one's head of phase line after accomplishing.After accomplishing the first half coil winding,, begin the 3rd section of coiling as stated above, the 4th section with coiling mold reverses its direction.
The coiling of interlayer oblique roller is as shown in Figure 2, and coiling is the 3rd section in proper order, and first section, the 4th section, second section.The 3rd section ground floor of coiling at first, coiling from bottom to top, the ground floor coiling tiltedly is pulled to second layer lower end with lead after accomplishing, and continues coiling from bottom to top, and by this way, this section is accomplished in coiling, and the tail head is cut off.On the mold height, stay the distance of second section coil then, coiling is first section as stated above.After the completion with the mold reverses its direction, with lead earlier with the 3rd section first firm welding, the 4th section of coiling according to the method described above then, second section of coiling in like manner at last.
The above record is merely the embodiment that utilizes the utility model technology contents, and modification, variation that any people who is familiar with this technology uses the utility model to do all belong to the claim that the utility model is advocated, and be not limited to embodiment.
