Description

Technical Field

[0001] The utility model relates to the technical field of transformer coils, in particular to an embedded fixing structure of a winding. Background Art

[0002] When the existing transformer is installed independently, multiple support gaskets are stacked at the lower end of the winding for support. There are gaps between the multiple support gaskets and they cannot form a whole. In addition, the multiple support gaskets and the winding comb-shaped stays cannot be embedded and installed in a stacked manner. When the transformer is running, the vibration of the winding will cause the support gasket to loosen and gradually fall off, which can easily cause the winding to slide down and fail.

[0003] To this end, we have introduced an embedded fixing structure for the winding. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides a technical solution: an embedded fixing structure of a winding, comprising an insulating cylinder 3, an upper flange 31 is provided at the top end of the insulating cylinder 3, a lower flange 32 is provided at the bottom end of the insulating cylinder 3, a plurality of comb-shaped support bars 1 are vertically provided between the upper flange 31 and the lower flange 32, the comb-shaped support bars 1 are connected to the outer surface of the insulating cylinder 3 by adhesive, and a plurality of independent windings 2 are provided in the comb-shaped support bars 1.

[0016] Specifically, the slot width H1 of the comb-shaped stay 1 is 2 MM larger than the width H2 of the winding 2 , so as to facilitate installation of the winding 2 into the tooth slots of the comb-shaped stay 1 .

[0017] Specifically, the tooth height of the comb-shaped stay 1 is greater than the height of the winding 2 , that is, the height from the bottom to the top of the teeth of the comb-shaped stay 1 is greater than the distance from the inner surface to the outer surface of the winding 2 .

[0018] Specifically, a connecting plate 21 is provided on the winding 2 at the bottom layer, and a screw hole 22 is provided on the connecting plate 21 .

[0019] Specifically, the winding 2 at the bottom layer is further provided with a joint 23 .

[0020] When the utility model is used, the winding 2 is connected to the comb-shaped stay 1, that is, the winding 2 is installed in the tooth groove of the comb-shaped stay 1. Since there are several comb-shaped stays 1 (for example, 6), the comb-shaped stays 1 and the winding 2 form a cylindrical shape, and then the back of the comb-shaped stay 1 is coated with adhesive, and then the comb-shaped stay 1 is put on the insulating tube 3, and the comb-shaped stay 1, the winding 2 and the insulating tube 3 are formed into a whole, which improves the overall structural stability and anti-vibration strength of the utility model, thereby improving the performance of the product.
