Description
Technical Field
The utility model relates to a transformer field especially relates to a transformer winding segmentation fixing device.
Background
Before casting, the transformer windings need to be fixed on a mold core, a certain gap exists between every two windings according to design, the existing method is to directly cut a piece of glass fiber mesh cloth, fold the glass fiber mesh cloth into a mesh cloth block with corresponding thickness, and plug the mesh cloth block between two adjacent windings; the method is rough, the precision is extremely poor, the windings are heavy, and the windings sink to a certain extent under the action of gravity when the mold core is in a vertical state, so that grid cloth blocks are compressed, and the distance between adjacent windings is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses make the improvement to the problem that above-mentioned prior art exists, promptly the utility model aims to solve the technical problem that a transformer winding segmentation fixing device is provided, and the precision is high, convenient to use.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a transformer winding segmentation fixing device, includes the unequal cushion of base and a plurality of thickness, be provided with the guide slot of two notch mutual dispositions on the base, be provided with the connecting plate on the cushion lateral wall, the terminal double-phase offside of connecting plate all is provided with the lug that is used for imbedding the guide slot, still includes the chock, the thickness and the guide slot width of chock equal, the width of chock equals with the interval between two guide slot insoles.
Further, the thickness of the pad is multiplied by at least 0.5 mm.
Furthermore, the upper part of the cushion block is provided with a convex part, and the bottom of the cushion block is provided with a concave part for accommodating the convex part of the bottom cushion block.
Furthermore, the base, the guide groove, the cushion block and the chock block are made of glass fiber.
Further, the cushion block, the connecting plate, the convex block and the convex part are integrally formed.
Compared with the prior art, the utility model discloses following beneficial effect has: the device is simple in structure, convenient to use and high in precision, and the gap between the windings cannot be changed.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Description
The first embodiment is as follows: as shown in fig. 1 to 4, a transformer winding segmentation fixing device includes a base 1 and a plurality of spacers 2 with different thicknesses, the base 1 is provided with two guide grooves 11 with opposite notches, a side wall of each spacer 2 is provided with a connecting plate 22, two opposite sides of the tail end of each connecting plate 22 are provided with bumps 23 used for being embedded into the corresponding guide groove 11, the transformer winding segmentation fixing device further includes a plug 3, the thickness of the plug 3 is equal to the width of the corresponding guide groove 11, and the width of the plug 3 is equal to the distance between the inner bottoms of the two guide grooves 11.
In this embodiment, the thickness of the pad is multiplied by at least 0.5 mm. Namely, the minimum thickness of the cushion block is 0.5mm, the thickness of the thicker cushion block is N times of 0.5mm, and N is more than 1.
In this embodiment, the upper portion of the cushion block 2 is provided with a convex portion 21, and the bottom of the cushion block 2 is provided with a concave portion for accommodating the convex portion of the bottom cushion block. Is convenient for stacking among the cushion blocks and avoids the deviation among the cushion blocks
In this embodiment, the base 1, the guide groove 11, the cushion block 2 and the chock block 3 are made of glass fiber.
In this embodiment, the pad 2, the connecting plate 22, the protrusion 23, and the protrusion 21 are integrally formed.
In this embodiment, the base 1 and the guide groove 11 are integrally formed.
When the winding die is used, as shown in figure 1, according to the arrangement of windings on the die core, the cushion blocks 2 with corresponding thicknesses are selected and stacked together to form a large cushion block, then two convex blocks of the large cushion block are embedded into the two guide grooves, then the length of the chock block 3 is cut into the thickness of the windings, the chock block is plugged into the two guide grooves, then the other large cushion block is embedded into the other large cushion block, then the chock block with corresponding length is plugged into the other large cushion block until the segmented fixing of all the windings is completed, and preferably, the last chock block which is parallel to the end parts of the guide grooves is plugged into the inlets of the two guide grooves, so. And finally, pouring the base, the guide groove, the cushion block and the chock block together with the winding.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
