Abstract
The utility model relates to a continuous coil structure for a transformer. The continuous coil structure comprises a coil (1), stays (2) and cushion blocks (3), wherein cushion strips (4) are respectively arranged between the stays (2) and the cushion blocks (3); an inner cylinder (5) and an outer cylinder (6) are arranged on the internal-diameter side and external-diameter side of the coil (1); the inner cylinder (5), the stays (2) on the internal-diameter side of the coil (1) and the cushion strips (4) form an inner guiding oil passage (7); the outer cylinder (6), the stays (2) on the external-diameter side of the coil (1) and the cushion strips (4) form an external guiding oil passage (8); and the cushion strips (4) between the stays (2) on the internal-diameter side and external-diameter side of the coil (1) are arranged in a transplacement manner. According to the continuous coil structure, a cycling pathway for the transformer oil is additionally arranged, the coil radiating effect is obvious, the coil strength is improved, and the service life of the transformer coil is prolonged. The continuous coil structure has the advantages of simple structure and convenience in disassembly, is particularly suitable for protection of the coil of large and medium-size oil-immersed transformers.
Description
Technical field
The utility model relates to a kind of transformer continuous winding structure.
Background technology
At present, big-and-middle-sized oil-filled transformer adopts continuous winding usually, and the subordinate is in disordered state in coil in the motion of transformer oil during operation, and mobile poor, the circulating path of transformer oil is also very short in the coil, causes the radiating effect of coil undesirable.
The utility model content
The purpose of the utility model just provides the desirable transformer continuous winding structure of a kind of radiating effect.
The purpose of the utility model is to realize through such technical scheme; A kind of transformer continuous winding structure; Comprise coil; And stay that is provided with between coil and cushion block, it is characterized in that: be provided with filler strip between the said stay and between the said cushion block, in the internal side diameter of said coil and outside diameter are provided with, enclosing tube and peripheral tube; Enclose in said tube form with the said stay of internal coil diameter side and said filler strip in the guiding oil duct, oil duct leads outside the said cushion block of said peripheral tube and coil outer diameter side and said filler strip form.
In order to increase circulating path, make transformer oil go up current downflow in an orderly manner along the guiding oil duct, the filler strip between the cushion block of filler strip between the stay of said internal coil diameter side and said coil outer diameter side shifts to install.
In order to guarantee the transformer built-in electrical insulation, prevent the inner appearance discharge of transformer, said filler strip is the paper washer bar; Enclose tube in said and enclose tube for paper with peripheral tube.
Owing to adopted technique scheme, the utlity model has following advantage:
1. between the stay of the internal side diameter of said lead and outside diameter, filler strip is set; And be provided with and enclose tube, make coil inside form inside and outside guiding oil duct, guarantee the last current downflow that transformer oil can only be orderly; Increased the radiating effect of transformer coil; Owing between transformer coil, increased filler strip and enclosed tube, coil intensity is improved, prolonged the useful life of transformer coil.
2. the filler strip on said lead internal side diameter and the outside diameter shifts to install, and has increased the circulating path of transformer oil, makes the coil radiating effect obvious.
3. the utility model is simple in structure, and convenient disassembly is specially adapted to the coil protect of big-and-middle-sized oil-filled transformer.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 looks cross-sectional schematic for the master of the utility model embodiment;
Fig. 2 radially places sketch map for the interior guiding oil duct of the utility model embodiment;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 radially places sketch map for the outer guiding oil duct of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But utility model is not limited to this execution mode; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment; Referring to accompanying drawing 2,3,4: a kind of transformer continuous winding structure; Comprise coil 1; And the stay that is provided with between coil 2 and cushion block 3, between said stay 2 and cushion block 3, be provided with paper washer bar 4, be provided with at the internal side diameter and the outside diameter of said coil 1 and enclose tube 5 and paper in the paper peripheral 6; Enclose the said stay 2 and the interior guiding of said paper washer bar 4 formation oil duct 7, guiding oil duct 8 outside the said cushion block 3 of said paper periphery tube 6 and coil 1 outside diameter and said paper washer bar 4 form of tube 5 and coil 1 internal side diameter in the said paper.
Referring to accompanying drawing 1, the filler strip 4 between the cushion block 3 of filler strip 4 between the stay 2 of said coil 1 internal side diameter and said coil 1 outside diameter shifts to install.
Claims (4)
1. transformer continuous winding structure; Comprise coil (1); And stay that is provided with between coil (2) and cushion block (3); It is characterized in that: be provided with filler strip (4) between the said stay (2) and between the said cushion block (3);, the internal side diameter of said coil (1) and outside diameter enclose tube (5) and peripheral tube (6) in being provided with, guiding oil duct (7) in the said stay (2) that encloses tube (5) and coil (1) internal side diameter in said forms with said filler strip (4), and oil duct (8) leads outside the said cushion block (3) of said peripheral tube (6) and coil (1) outside diameter and said filler strip (4) formation.
2. according to the described transformer continuous winding of claim 1 structure, it is characterized in that: the filler strip (4) between the cushion block (3) of filler strip (4) between the stay (2) of said coil (1) internal side diameter and said coil (1) outside diameter shifts to install.
