Abstract
The utility model discloses an improved water-cooled transformer. The improved water-cooled transformer comprises an iron core and a winding, wherein the winding consists of an outer winding coil and an inner winding coil; one group of the outer winding coil and the inner winding coil is wound by a solid-core wire and the other group is wound by a hollow-core copper pipe; and a heat-transfer and insulating isolated layer is arranged between the outer winding coil and the inner winding coil. As one group of the two coils is wound by the solid-core wire and the other group is wound by the hollow-core copper pipe, when temperature rising is caused by the running transformer, the winding coil wound by the hollow-core copper pipe can realize water cooling; meanwhile, the improved water-cooled transformer is benefit for the heat radiation of the other winding coil, thereby effectively lowering the temperature rising of the transformer, prolonging the service life of the transformer, improving the overload capacity, saving materials and thoroughly solving the ionizing phenomenon.
Description
Technical field:
The utility model relates to the electric equipment technical field, especially relates to the winding coil structure of transformer.
Background technology:
Transformer is one of electric equipment commonly used in the industrial circle, traditional transformer device structure all is made up of interior winding coil, outer winding coil (or claiming primary and secondary coil) and iron core, need there be insulation system that it is separated between interior winding coil and the outer winding coil, to guarantee the operate as normal of transformer.It is bad that the insulation of winding coil and outer winding coil and heat radiation needed to use more material and radiating effect at present general transformer was realized.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of improved water-cooled transformer is provided that it not only has production and characteristics easy to use, and safe and reliable practicality.
For achieving the above object, the improved transformer of the utility model includes iron core and winding, wherein, winding is made of outer winding coil and interior winding coil, one group in described outer winding coil and the interior winding coil is twined by solid conductor, another group is then twined by hollow copper tubing, is provided with the separator that conducts heat and insulate between outer winding coil and the interior winding coil.
The beneficial effects of the utility model are: owing to have one group to be twined by hollow copper tubing in two groups of winding coils, another group is twined by solid conductor, when the transformer operation produces temperature rise, can realize water-cooled by the winding coil that hollow copper tubing twines, help the heat radiation of another winding coil simultaneously, can effectively reduce the transformer temperature rise, prolong the useful life of transformer, and improve overload capacity, save material, can also solve ionization phenomena completely.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
See shown in the accompanying drawing 1: water-cooled transformer of the present utility model includes iron core 10 and winding 20, and wherein, winding 20 is made of outer winding coil 21 (low-pressure side) and interior winding coil 22 (high-pressure side); Outer winding coil 21 is twined by solid conductor, and interior winding coil 22 is twined by hollow copper tubing, is provided with the separator 23 that conducts heat and insulate between outer winding coil 21 and the interior winding coil 22.When the transformer temperature rise, interior winding coil 22 can be realized water-cooled, helps the heat radiation of outer winding coil 21, and effect is very good.
Need to prove: also can adopt outer winding coil 21 to twine by hollow copper tubing, and the pattern that interior winding coil 22 is twined by solid conductor.
