Abstract

The utility model discloses a dry type transformer coil structure comprising a shell, wherein a high voltage coil and a low voltage coil are respectively arranged in the shell and are connected by a connecting piece, an insulating cylinder is arranged between the high voltage coil and the low voltage coil, and a heat dissipation air channel and a coil outlet port are respectively formed in the high voltage coil and the low voltage coil. According to the dry type transformer coil structure, the size of the transformer is small, meanwhile, the coil winding efficiency is improved, the manufacturing cost is saved, furthermore, the heat dissipation effect is good, and lines are not easy to knot.

Description

Dry transformer coil structure
Technical field
The utility model relates to a kind of loop construction, particularly a kind of dry transformer coil structure.
Background technology
Coil is important component part indispensable in the transformer, and the cross-sectional area shape of general transformer coil is mainly circle, like this so that the transformer wider width, volume is larger, not only waste material, strengthened simultaneously cost of manufacture, be unfavorable for the saving of resource.Simultaneously when transformer coil is poured into a mould, also exist certain deficiency, and heat dispersion is short of to some extent also.Therefore, need to make certain improvement, just can better meet the demand in market.
Summary of the invention
The purpose of this utility model just is to provide a kind of dry transformer coil structure, can address the above problem fully.
To achieve these goals, the technical solution adopted in the utility model is such: dry transformer coil structure of the present utility model, comprise housing, be respectively equipped with high-tension coil and low-voltage coil in the housing, connect by connector between high-tension coil and the low-voltage coil, also be provided with insulating cylinder between high-tension coil and the low-voltage coil, be respectively equipped with heat radiation air flue and outlet port on high-tension coil and the low-voltage coil.
As preferably, described high-tension coil and low-voltage coil all adopt the enamelled wire coiling to form.
As preferably, be connected by the epoxide resin material layer between described housing and high-tension coil and the low-voltage coil.
As preferably, the cross-sectional area of described high-tension coil and low-voltage coil is rectangle, and its four angles are circular arc.
Compared with prior art, the utility model has the advantage of: this dry transformer coil structure has improved coil winding efficient simultaneously so that the transformer size is less, has saved cost of manufacture, and radiating effect is good in addition, and circuit is difficult for knotting.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, dry transformer coil structure of the present utility model, comprise housing 7, be respectively equipped with high-tension coil 1 and low-voltage coil 2 in the housing 7, connect by connector 3 between high-tension coil 1 and the low-voltage coil 2, also be provided with insulating cylinder 4 between high-tension coil 1 and the low-voltage coil 2, be respectively equipped with heat radiation air flue 4 and outlet port 6 on high-tension coil 1 and the low-voltage coil 2, described high-tension coil 1 and low-voltage coil 2 all adopt the enamelled wire coiling to form, be connected by the epoxide resin material layer between described housing 7 and high-tension coil 1 and the low-voltage coil 2, the cross-sectional area of described high-tension coil 1 and low-voltage coil 2 is rectangle, and its four angles are circular arc.
Also be provided with insulating cylinder 4 between high-tension coil 1 and the low-voltage coil 2, make its insulation property good; Be respectively equipped with heat radiation air flue 4 and outlet port 6 on high-tension coil 1 and the low-voltage coil 2, heat radiation air flue 4 has good heat sinking function, and the design of outlet port 6 makes its coil be difficult for coiling; High-tension coil 1 and low-voltage coil 2 all adopt the enamelled wire coiling to form, and be reasonable in design; Be connected by the epoxide resin material layer between housing 7 and high-tension coil 1 and the low-voltage coil 2, adopt disposal pouring, production efficiency is high; The cross-sectional area of high-tension coil 1 and low-voltage coil 2 is rectangle, and its four angles are circular arc, so that coil dimension is less, have improved coiling efficient.
