The C level three dimensional wound core dry-type transformer coil that suspension type is installed
Technical field
The invention belongs to the technical field of power equipment, specifically be meant the C level three dimensional wound core dry-type transformer coil that a kind of suspension type is installed.
Background technology
At present, the conventional dry transformer adopts console mode to install more, coil air flue direction with the main empty path direction during with forced air cooling wind direction consistent, be the vertical direction air flue, help coil like this and dispel the heat.When the transformer adopting suspension type was installed, its wind direction mostly was horizontal direction.For guaranteeing that coil can rationally dispel the heat, the coil air flue also need be made horizontal direction, and is promptly consistent with wind direction.
Summary of the invention
The object of the present invention is to provide a kind of heat radiation that promptly is beneficial to, save the C level three dimensional wound core dry-type transformer coil in space again.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the C level three dimensional wound core dry-type transformer coil that a kind of suspension type is installed comprises iron core, high-tension coil, low-voltage coil, electrostatic shielding and cushion block;
Iron core is provided with several axial stays along iron core, and described cushion block is disposed radially, and an end of cushion block and stay are fitted;
Low-voltage coil is positioned at upper and lower unshakable in one's determination, and high-tension coil is positioned at middle part unshakable in one's determination, and electrostatic shielding is arranged between high-tension coil and the low-voltage coil;
Be provided with cushion block between each line cake of high-tension coil and between each line cake of low-voltage coil, the gap between adjacent two line cakes constitutes little air flue, is provided with cushion block between high-tension coil and the low-voltage coil, and the gap between high-tension coil and the low-voltage coil constitutes big airways.
The C level three dimensional wound core dry-type transformer coil that described suspension type is installed, its special character is: described cushion block is swallow-tail form.
The C level three dimensional wound core dry-type transformer coil that described suspension type is installed, its special character is: be provided with cushion block between static cake and high-tension coil and the low-voltage coil, a static cake is arranged on the cushion block;
Gap between static cake and the high-tension coil constitutes first air flue, and the gap between static cake and the low-voltage coil constitutes second largest air flue, and first air flue and second largest air flue constitute big airways.
The C level three dimensional wound core dry-type transformer coil that a kind of suspension type of the present invention is installed, owing to adopted above-mentioned structure, the air flue direction is consistent with the erecting bed wind direction in use, can guarantee transformer good heat radiation when moving.In addition, this kind of high and low pressure coil arrangement architecture has effectively dwindled the size of coil horizontal direction, and then has dwindled the volume of transformer; The present invention has changed the air flue arragement direction, and wind direction is consistent when making it with forced air cooling, can make the coil better heat-radiation effect under the equal conditions and reduce the coil windings size, reaches the purpose of saving the space.

Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail, but does not constitute any limitation of the invention.
As shown in Figure 1, the C level three dimensional wound core dry-type transformer coil that a kind of suspension type is installed comprises iron core 1, high-tension coil 2, low-voltage coil 3, electrostatic shielding 4 and cushion block 5,
Unshakable in one's determination 1 is provided with several axial stays 6 along iron core 1, and described cushion block 5 is disposed radially, and an end of cushion block 5 is fixedlyed connected with stay (6);
Low-voltage coil 3 is positioned at unshakable in one's determination 1 upper and lower, and high-tension coil 2 is positioned at unshakable in one's determination 1 middle part, and electrostatic shielding 4 is arranged between high-tension coil 2 and the low-voltage coil 3; Every phase coil comprises high-tension coil 2 and low-voltage coil 3.
Be provided with cushion block 5 between high-tension coil 2 each line cake and between low-voltage coil 3 each line cake, the gap between adjacent two line cakes constitutes little air flue, and the gap between high-tension coil 2 and the low-voltage coil 3 constitutes big airways.
Described cushion block 5 is swallow-tail form.
Being provided with cushion block 5, one static cakes 4 between static cake 4 and high-tension coil 2 and the low-voltage coil 3 is arranged on the cushion block 5;
Gap between static cake 4 and the high-tension coil 2 constitutes first air flue 71, and the gap between static cake 4 and the low-voltage coil 3 constitutes second largest air flue 72, and first air flue 71 and second largest air flue 72 constitute big airways.
During use, the air flue direction is consistent with the erecting bed wind direction, can guarantee transformer good heat radiation of when operation.In addition, this kind of high and low pressure coil arrangement architecture has effectively dwindled the size of coil horizontal direction, and then has dwindled the volume of transformer.
Above-described only is preferential execution mode of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
