Abstract
The utility model relates to a square coil structure of a dry type transformer, which belongs to the technical field of transformers. The technical scheme is that the square coil structure comprises a molding insulation barrel (1), radiating air channels (2), and a coil conductor (3). The molding insulation barrel is used as a frame, the coil conductor is wound on the molding insulation barrel to form a coil, and one or a plurality of radiating air channels are arranged in the front and back direction of the coil. The square coil structure of the dry type transformer has the advantages that the radiating channels are not arranged on a window side of the coil and are arranged in the front and back direction, electrical performance of the transformer is not changed, temperature of the coil is lowered, and short circuit resisting capacity of the coil is improved. The air channels are not arranged on an iron core side, a center distance Mo is reduced, usage quantity of iron is reduced, and cost of the transformer is greatly reduced.
Description
Technical field
The utility model relates to a kind of dry-type transformer matrix loop structure, belongs to the transformer technology field.
Background technology
Iron core is the dry-type transformer coiling of square-section; The winding structure of background technology is that major axis, short-axis direction all have the heat radiation air flue, but because the heat radiation air flue of alternate direction has iron core to block, the radiating effect in the window unshakable in one's determination is bad; Heat can not in full force and effectly come out; Thereby the temperature of coil is raise, and the life-span of insulating part reduces, and finally reduces the useful life of transformer.
The utility model content
The purpose of the utility model provides a kind of dry-type transformer matrix loop structure, the alternate heat of coil that can effectively leave, and alternate direction does not have air flue simultaneously; Shortened centre-to-centre spacing again; Reduce the consumption of iron, the transformer cost is reduced, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is:
A kind of dry-type transformer matrix loop structure comprises profiled insulation tube, heat radiation air flue, coil-conductor, and the profiled insulation tube is done skeleton, and coil-conductor constitutes coil on the profiled insulation tube, and the fore-and-aft direction of coil is provided with one or more heat radiation air flues.
Coil adopts multilayer laminar or the coiling of paper tinsel formula to form, and window side is not with the heat radiation air flue in the coiling process.
The good effect of the utility model is: the utility model coil window oral-lateral is not with the heat radiation air flue; The heat radiation air flue of coil is arranged on fore-and-aft direction; The electric property that has guaranteed transformer is constant, thereby the temperature of coil is reduced, and has strengthened the anti-short circuit capability of coil; Core side is not with the heat radiation air flue simultaneously, and centre-to-centre spacing Mo is reduced, and reduces the consumption of iron, and the transformer cost also reduces greatly.
Description of drawings
Fig. 1 is the utility model embodiment sketch map;
Among the figure: profiled insulation tube 1, heat radiation air flue 2, coil-conductor 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
A kind of dry-type transformer matrix loop structure comprises profiled insulation tube 1, heat radiation air flue 2, coil-conductor 3, and the profiled insulation tube is done skeleton, and coil-conductor constitutes coil on the profiled insulation tube, and the fore-and-aft direction of coil is provided with one or more heat radiation air flues.Coil adopts multilayer laminar or the coiling of paper tinsel formula to form, and window side is not with the heat radiation air flue in the coiling process.
Claims (2)
1. dry-type transformer matrix loop structure; It is characterized in that comprising profiled insulation tube (1), heat radiation air flue (2), coil-conductor (3); The profiled insulation tube is done skeleton, and coil-conductor constitutes coil on the profiled insulation tube, and the fore-and-aft direction of coil is provided with one or more heat radiation air flues.
