Abstract
The invention discloses a coil of a suspended C-level three-dimensional wound core dry-type transformer, which comprises iron cores (1), high voltage coils (2), low voltage coils (3), electrostatic shields (4) and cushion blocks (5). The iron cores (1) are provided with gaggers (6). The low voltage coils are positioned at the upper parts and the lower parts of the corresponding iron cores. The high voltage coils are positioned at the middle parts of the corresponding iron cores. The electrostatic shields (4) are arranged between the corresponding high voltage coils and the corresponding low voltage coils. The cushion blocks (5) are arranged between wire disks of the high voltage coils (2) and between wire disks of the low voltage coils (3). A small air path is formed by a gap between each two adjacent wire disks. Big air paths are formed by gaps between the high voltage coils (2) and the low voltage coils (3). The direction of each air path is consistent with the wind direction of an installation site, so that excellent heat dissipation in the operation process of the transformer can be ensured. Moreover, due to the arrangement structure of the high and low voltage coils, the sizes of the coils in the horizontal direction are effectively reduced, so that the volume of the transformer is reduced.
Description
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, mostly its wind direction 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 scheme that the present invention adopts 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 said 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: said 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 electrostatic shielding and high-tension coil and the low-voltage coil, an electrostatic shielding is arranged on the cushion block;
Gap between electrostatic shielding and the high-tension coil constitutes first air flue, and the gap between electrostatic shielding 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.
