The adjustable coil-compressing device disclosed by the utility model can be used for compaction installation of transformer coils of various specifications, can prevent the coils from deforming, has strong university, and is simple in structure.
Description
Technical field
The utility model relates to technical field of transformer manufacturing, relates in particular to the instrument of oil-filled transformer coil when compressing.
Background technology
In the transformer manufacture process, the making of coil is most important, its vertically and the width of cloth to size, and the external form installation dimension of coil after compressing directly has influence on the inherent quality and the assembly quality of transformer.Can the thrust transformer of coil withstand the impact of short-circuit electromotive force, and outside the Pass the factors such as mechanical strength, insulation crudy, winding technique quality of removing compressing structure had, the thrust of coil played an important role.Therefore, in the manufacture process of transformer coil, need press-fit coil.At present; The transformer coil press mounting instrument generally includes top board, lower platen and clamping screw, and top board and lower platen are arranged with perforation, and coil places between top board and the lower platen; Clamping screw can compress coil through nut through perforation or single symmetrical holes.The transformer coil press mounting instrument of said structure because top board and lower platen are arranged with perforation, need adopt different press mounting tools to the coil of different-diameter, and its versatility is poor, causes the transformer coil press mounting instrument of the supporting a lot of specifications of enterprise's needs.
The utility model content
The utility model coil compressing device is the shortcoming to above-mentioned existence, and a kind of transformer coil press mounting device is provided, and it can be applied to press-fiting of multiple different size transformer coil, highly versatile.
The technical scheme that technical problem adopted that the utility model solves is: adjustable oil-filled transformer coil compressing device; Comprise top board, lower platen and clamping screw; It is characterized in that top board and lower platen are arranged with elongated slot up and down, clamping screw is located in the outer of the elongated slot of top board and lower platen.Clamping screw can be in elongated slot be regulated arbitrarily, with the use of the transformer coil that adapts to different-diameter.
During concrete the use, be equipped with positioning screw on the interior edge of the elongated slot of top board and lower platen.During use, positioning screw is as coil location usefulness, and positioning screw is located at the inner ring that need compress coil, and set winding is positioned at position placed in the middle effectively, and the clamping screw at the place, outer of the elongated slot of pressing plate and lower platen is used to compress the effect of coil.
During concrete the use, top board and lower platen are circular pressing plate.
During concrete the use, the elongated slot of top board and lower platen respectively is provided with four.
During concrete the use, the center of top board and lower platen offers center positioning hole.
The utility model makes the perforation of original technology into elongated slot, can adapt to press-fiting of the big or small coil of difference, increases the versatility of press mounting tool widely.
The beneficial effect of the utility model is: the transformer coil press mounting that the utility model coil compressing device can satisfy plurality of specifications uses, and prevents coil variations, and highly versatile is simple in structure.
Description of drawings
Below in conjunction with accompanying drawing and instance to the further brief description of the multi-functional oil-filled transformer coil compressing device of utility model.
Fig. 1 is the structure vertical view of the utility model instance.
Structural representation when Fig. 2 is the use of the utility model instance.
Among the figure: 1, top board 2, lower platen 3, positioning screw 4, clamping screw 5, coil 6, center positioning hole 7, elongated slot 8, nut.
Embodiment
Like Fig. 1 and Fig. 2; Adjustable oil-filled transformer coil compressing device comprises top board 1, lower platen 2 and four clamping screws 3 and four positioning screws 4, and top board 1 is arranged with elongated slot 7 up and down with lower platen 2; Clamping screw 3 is located in the outer of the elongated slot 7 of top board 1 and lower platen 2; Positioning screw 4 is located at the interior edge of the elongated slot 7 of top board 1 and lower platen 2, and top board 1 is circular pressing plate with lower platen 2, and the elongated slot 7 of top board 1 and lower platen 2 respectively is provided with four; The center of top board 1 and lower platen 2 offers center positioning hole 6, and the two ends of clamping screw 3 and positioning screw 4 are fastening with nut 8.Clamping screw 3 can be regulated arbitrarily in elongated slot 7; Use with the transformer coil that adapts to different-diameter; Positioning screw 4 is used as coil location; Positioning screw 4 is located at the inner ring that need compress coil, and set winding is positioned at position placed in the middle effectively, and the clamping screw 3 at the place, outer of the elongated slot 7 of top board 1 and lower platen 2 is used to compress the effect of coil.
Like Fig. 1 and Fig. 2, the oil-filled transformer coil compresses technical process: promptly place lower platen 2 levels on the flat board, and different from main importing separately among the elongated slot 7 four coil location screw rods 4 from four; Hang in coil 5, first modulation coil 5 location cover top board 1; Centralized positioning, four elongated slots, 7 vertical symmetry import clamping screw 3; Just press tight screw rod 3, the modulation coil positioning screw 4 again, and last fastening clamping screw 3 gets final product.The utility model coil compressing device makes the perforation of original technology into elongated slot 7, can adapt to press-fiting of the big or small coil of difference, increases the versatility of press mounting tool thus widely.
