Abstract
The utility model relates to a dry type transformer, in particular to a dry type transformer coil and iron core assembling structure which comprises a dry type transformer shell, the shell is fixed on a substrate, the iron core is arranged inside the shell, a low-voltage coil and a high-voltage coil are wound around the iron core, a cooling air passage is arranged in the middle of the low-voltage coil, and an insulating rubber strip for fixing the iron core and the coils is arranged between the iron core and the low-voltage coil. After adopting the above structure, on the one hand, the iron core can be well fixed by the insulating rubber strip arranged between the iron core and the coil, so as to effectively lower the noise of the transformer in working, generated due to vibration of the iron core; on the other hand, the distances between all the parts of the low-voltage coil and the iron core are consistent, so that the coils are on a concentric circle.
Description
Technical field
The utility model relates to a kind of dry-type transformer, particularly the assembly structure between a kind of dry-type transformer coil and the iron core.
Background technology
Dry-type transformer relies on cross-ventilation to cool off, and generally is used for localized lighting, electronic circuit, the isallobaric device of plant equipment.Transformer is to add primary and secondary coil at iron core, and the magnetic field that produces by primary coil changes in iron core, and it is output voltage that secondary coil produces induced voltage.But iron core itself is conductor, and wherein the variation in magnetic field will produce eddy current loss.Improve the efficient of transformer, must reduce eddy current loss.Therefore iron core can not be made with monoblock iron, but with the silicon steel sheet of book very, slices build up iron core, substantially insulate between sheet, and the eddy current of generation only limits in the very thin silicon steel sheet of every a slice, and eddy current loss greatly reduces.Build up iron core with blocks of silicon steel sheet just, under the effect of AC magnetic field, can produce vibration between the silicon steel sheet, send " drone " sound.
So the noise that control transformer produces is the subject matter of design of transformer person's research always.
Summary of the invention
The utility model technical issues that need to address provide and a kind ofly can reduce the dry-type transformer iron core of iron core noise and the assembly structure of coil.
For solving above-mentioned technical problem, the utility model dry-type transformer coil and iron core assembly structure comprise dry-type transformer case, described shell is fixed on the pedestal, described iron core is arranged on enclosure, low pressure and high-tension coil are full of in described iron core periphery, be provided with cooling airway in the middle of the described low-voltage coil, be provided with the insulation adhesive tape of secured core and coil between described iron core and the low-voltage coil.
Described coil all is provided with up and down the cross-over block of fixed coil.
After adopting said structure, the insulation adhesive tape that is arranged between iron core and the coil can well be fixed iron core on the one hand, effectively reduces the noise that produces because of core vibration in the transformer work; The distance that can guarantee on the other hand low-voltage coil each several part and iron core is consistent, so that coil is on the concentric circles.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model dry-type transformer.
Fig. 2 is the internal view of the utility model dry-type transformer.
Among the figure: 1 is pedestal, and 2 is shell, and 3 is iron core, and 4 is low-voltage coil, and 5 is high-tension coil, and 6 are the insulation adhesive tape, and 7 is cross-over block, and 8 is cooling airway
Embodiment
Dry-type transformer as shown in Figure 1 comprises dry-type transformer case 2, and described shell 2 is fixed on the pedestal 1, and described iron core 3 is arranged on shell 2 inside.
The utility model dry-type transformer coil and iron core assembly structure are for being full of low pressure and high-tension coil 5 in described iron core 3 peripheries as shown in Figure 2, be provided with cooling airway 8 in the middle of the described low-voltage coil 4, be provided with the insulation adhesive tape 6 of secured core and coil between described iron core 3 and the low-voltage coil 4.Insulation adhesive tape 6 can well be fixed iron core 3 so on the one hand along four jiaos of settings of iron core 3, effectively reduces the vibration that iron core occurs when transformer is worked, thereby has reduced the noise that core vibration produces; The adhesive tape that insulate on the other hand 6 has well been fixed the position of low-voltage coil, so that distance is consistent between low-voltage coil 4 each several parts and the iron core 3, low-voltage coil integral body is on the concentric circles of iron core periphery like this.
Described coil all is provided with up and down the cross-over block 7 of fixed coil, so just from well fixing coil windings on the both direction up and down.
Claims (2)
1. a dry-type transformer coil and iron core assembly structure, comprise dry-type transformer case, described shell is fixed on the pedestal, described iron core is arranged on enclosure, low pressure and high-tension coil are full of in described iron core periphery, be provided with cooling airway in the middle of the described low-voltage coil, it is characterized in that: the insulation adhesive tape that is provided with secured core and coil between described iron core and the low-voltage coil.
2. according to dry-type transformer coil claimed in claim 1 and iron core assembly structure, it is characterized in that: described coil all is provided with up and down the cross-over block of fixed coil.
