Embodiment 1

[0031] Such as Figure 1-Figure 8 As shown, a foil coil winding mold with an air channel includes an inner mold 1, an air channel rod positioning plate 2, an air channel rod 3, an outer mold 4, an end template 5, and an inner mold leading positive mold 6;

[0032] The inner mold 1 is cylindrical, and the two ends of the inner mold 1 are respectively fixed with an annular airway stick positioning plate 2, and the end surface of the airway stick positioning plate 2 is provided with a mounting hole 201 for fixing the airway stick 3, and the two airway sticks A plurality of airway rods 3 are evenly fixed between the mounting holes 201 of the positioning plate 2, and the plurality of airway rods 3 form an airway rod layer outside the inner mold 1;

[0033] The lower layer winding 7 is wound between the airway rod layer and the inner mold 1, and the upper layer winding 8 is wound outside the airway rod layer;

[0034] The outer mold 4 is set outside the inner mold 1 after the windi...

Embodiment 2

[0044] Such as figure 2 , image 3 As shown, the airway rod positioning plate 2 is an annular plate provided with an intermittent joint 202, the annular plate is placed on the end of the inner mold 1, and the airway rod positioning plate 2 is fixed on the inner mold 1 by locking the intermittent joint 202 with screws .

[0045] The airway stick positioning plate 2 is provided with four sections of C-shaped arc holes equally divided with the same center, and the C-shaped arc holes are used as the installation holes 201 of the airway stick 3 . Other structures are the same as in Embodiment 1.

[0046] The airway stick positioning plate 2 is an annular plate provided with intermittent joints 202, and has few fastening screws, which is convenient for installation on the inner mold 1 and for easy disassembly; the C-shaped circular arc hole with the same center is used to facilitate the installation of the airway stick 3 . The spacing of the airway rods 3 can be set as required...

Embodiment 3

[0048] Such as Image 6 As shown, the outer mold 4 and the end template 5 are locked and fixed by a long screw 9 outside the outer mold 4 .

[0049] A silicone rubber sealing plate 10 is used to seal between the ends of the inner mold 1 , the outer mold 4 and the end template 5 .

[0050] An annular positioning template 16 is provided inside the silicone rubber sealing plate 10 , and a positioning template 16 is respectively provided between the outer circumference of the inner mold 1 and the airway rod 3 , and between the inner circumference of the outer mold 4 and the airway rod 3 . The positioning template 16 plays a guiding role, so that the inner mold 1 and the outer mold 4 are poured to form a regular circle.

[0051] One side of the outer mold 4 is provided with a branch wiring template 11, on which the wiring insert 12 (inserts such as tap nuts) is fixed, and the wiring insert 12 is electrically connected with the upper winding 8 and the lower winding 7.

Abstract

The invention discloses a foil type coil winding mold with an air channel, and belongs to the technical field of dry type transformer coils. The mold comprises an inner mold, an air passage rod positioning plate, an air passage rod, an outer mold, an end mold plate and an inner mold straightening mold, wherein the inner mold is cylindrical, annular air channel rod positioning plates are fixed to the two ends of the inner mold respectively, mounting holes used for fixing air channel rods are formed in the end faces of the air channel rod positioning plates, a plurality of air channel rods are evenly fixed between the mounting holes of the two air channel rod positioning plates, and the air channel rods form an air channel rod layer on the outer side of the inner mold; the lower layer winding is wound between the air channel rod layer and the inner mold, and the upper layer winding is wound on the outer side of the air channel rod layer. The air channel rod positioning plate is installed on the outer side of the inner mold, after the lower layer winding is wound, the air channel rod is inserted, then the upper layer winding is wound, and a heat dissipation air channel can be reserved more conveniently when a coil is wound; the foil type coil winding die is simple in structure, winding and die filling are convenient, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a foil-type coil winding mold with an air channel, which belongs to the technical field of dry-type transformer coils. Background technique [0002] Dry-type transformers will generate a lot of heat during operation. Therefore, in order to increase the heat dissipation area of ​​large-capacity transformers, it is necessary to place air passages on the high and low voltage coils to reduce the temperature rise of the transformer coils. Foil-wound high-voltage coils of resin-cast dry-type transformers. Since the winding material is copper strip (or aluminum strip), the existing coil winding process and equipment cannot place air passages in this foil coil. When the transformer capacity is large , unable to meet the cooling requirements. Therefore, a foil coil winding mold with an air channel is designed, which can solve the problem of setting the air channel in the foil coil. Contents of the invention [0003] The technical pr...
