Abstract
The utility model discloses a transformer coil's novel stay structure, transformer coil includes line cake, insulating cylinder, stay and cushion, the stay sets up at the insulating cylinder surface, the coiling of line cake is separated through the cushion of fixing on the stay between the line cake on the stay, the anterior contact surface with the line cake of stay is the arcwall face, anterior arcwall face of stay and the transition of stay side adoption fillet. The utility model discloses a novel stay is the arcwall face at the contact surface of anterior line cake, makes the fine laminating of line cake and stay together, and the coiling of line cake is inseparabler, simultaneously, the anterior arcwall face of stay passes through with stay side adoption fillet, avoids the insulating epidermis of scratch wire, improves the factor of safety of coil.
Description
Technical field
The utility model relates to field transformer, is specifically related to a kind of novel stay structure of transformer coil.
Background technology
As shown in Figure 1, have a kind of transformer coil structure to be continous way at present, its line cake 1 is wound on stay 3, is separated between line cake 1 and line cake 1 by the cushion block 4 be fixed on stay 3.The structure of existing stay 3 as shown in Figure 2, the face 31 that stay 3 contacts with line cake 1 is plane, the face 32 that stay 3 contacts with insulating cylinder 2 is plane, and the face 31 of stay 3 is right angle 33 with the angle of side, when coiling line cake 1, the insulation epidermis of the right angle 33 of stay 3 very easily scratch wire, have potential safety hazard, and line cake 1 and insulating cylinder 2 are circular, as shown in Figure 1, line cake 1 and stay 3 contact-making surface are fitted bad, and stay 3 and insulating cylinder 2 contact-making surface are fitted bad.
Utility model content
In order to solve existing stay and line cake can not be fitted very well, and the problem of the insulation epidermis of the easy scratch wire in the right angle of stay, the purpose of this utility model is the novel stay structure providing a kind of transformer coil, this stay front portion adopts the arcwall face of fitting very well with line cake, and adopt round-corner transition, avoid scratch wire.
The technical scheme that the utility model adopts is:
A kind of novel stay structure of transformer coil, described transformer coil comprises line cake, insulating cylinder, stay and cushion block, described stay is arranged on insulating cylinder outer surface, described line cake is wound on stay, separated by the cushion block be fixed on stay between line cake, described stay is anterior is arcwall face with the contact-making surface of line cake, and the anterior arcwall face of described stay and stay side adopt round-corner transition.
The beneficial effects of the utility model are:
Compared with prior art, novel stay of the present utility model is arcwall face at the contact-making surface of anterior line cake, and line cake and stay are well fit together, and the coiling of line cake is tightr; Meanwhile, arcwall face and the stay side of stay front portion adopt round-corner transition, avoid the insulation epidermis of scratch wire, improve the coefficient of safety of coil.
As the further improvement of technique scheme, the contact-making surface of described stay rear portion and insulating cylinder is also arcwall face, and arcwall face and the insulating cylinder at stay rear portion are well fitted, and make the structure of coil more firm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the schematic cross-section of existing continuous transformer coil;
Fig. 2 is the structural representation of existing stay;
Fig. 3 is the schematic cross-section of the transformer coil adopting novel stay;
Fig. 4 is the structural representation of novel stay of the present utility model.
Embodiment
With reference to Fig. 3, Fig. 4, the preferred embodiment that the utility model provides, a kind of novel stay structure of transformer coil, described transformer coil comprises line cake 1, insulating cylinder 2, stay 5 and cushion block 4, stay 5 is arranged on insulating cylinder 2 outer surface, line cake 1 is wound on stay 5, is separated between line cake 1 by the cushion block 4 be fixed on stay 5.Stay 5 can stretch forming, also can machine work be shaped, and stay 5 is anterior is arcwall face 51 with the contact-making surface of line cake 1, and the arcwall face 51 of stay adopts fillet 53 transition with side, and the contact-making surface of stay 5 rear portion and insulating cylinder 2 is also arcwall face 52.Due to novel stay of the present utility model arranging arcwall face 51,52 and fillet 53, when coiling line cake 1, wire insulation epidermis can not be damaged, and line cake 1 and stay 5 contact-making surface are fitted well, stay 5 and insulating cylinder 2 contact-making surface are fitted well, and the structure of coil is compacter, firm.
Above concrete structure and sized data illustrate preferred embodiment of the present utility model, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
Claims (2)
