The inner winding supporting framework is composed of a paper barrel, an insulation paper layer wound outside the paper barrel, and copper foil wound outside the insulation paper layer; the paper barrel is composed of a cable paper inner layer, a rhombic-grid glue applying paper layer and a cable paper outer layer. The thickness of the cable paper inner layer is 0.03-1mm, the thickness of the rhombic-grid glue applying paper layer is 5-10mm, and the thickness of the cable paper outer layer is 0.03-1mm. After winding of the paper barrel is completed, strap mould pressing fitting is performed, the pressed paper barrel is placed into a drying room to be dried and cured so that rhombic-grid glue applying paper can be mutually pasted and cured, and a curing layer with supporting force is formed. The supporting framework is high in borne internal stress, good in stability and applicable to the amorphous alloy transformer, the capacity for resisting sudden short circuits of the transformer is improved, the service life of the transformer is prolonged, and the manufacturing process is easy to perform.
Description
Technical field
The utility model relates to a kind of amorphous alloy transformer, particularly winding support frame in a kind of high strength rectangle being applied in amorphous alloy transformer.
Background technology
Amorphous alloy transformer is because no-load loss is little, energy savings, obtained application widely.The shortcoming of amorphous alloy transformer is: the iron core of transformer amorphous molecular structure when being subject to external force occurs chaotic, and no-load loss sharply increases.In existing amorphous alloy transformer coil, the support frame of winding is the rectangle square tube that cardboard surrounds, then coiling Copper Foil cooperation interlayer water chestnut lattice insulating paper, is then placed on amorphous alloy iron core.Current amorphous alloy transformer is when sudden short circuit, what interior winding bore is to internal stress, the skeleton bearing capacity that cardboard surrounds is inadequate, internal stress can be delivered on the iron core of non-crystaline amorphous metal, thereby make amorphous alloy iron core stressed, no-load loss sharply rises, and destroys what is more amorphous alloy iron core, and the situation of iron core scaling loss occurs repeatedly.Therefore,, in order to strengthen the support between interior winding and iron core, generally can improve by increasing the measures such as stay number, interior winding employing liner high-strength rigid paper web the radially dynamic stability of winding.But stay difficult control of aliging with cushion block in manufacture process, causes stressed badly, bearing capacity is poor.
So winding has a high-intensity support frame to bear internal stress in transformer coil, just can avoid no-load loss to rise, protection iron core, the useful life of prolongation transformer.
Summary of the invention
The technical problems to be solved in the utility model is to provide winding support frame in a kind of high strength rectangle, and in strengthening, the radially internal stress ability to bear of winding, effectively improves the anti-sudden short circuit ability of transformer, extends the useful life of transformer.
For solving the problems of the technologies described above, winding support frame in a kind of high strength rectangle, is characterized in that:
Described interior winding support frame is comprised of paper web, insulating paper layer outside paper web and the Copper Foil outside insulating paper layer;
Described paper web is comprised of cable paper internal layer, water chestnut lattice glue ply of paper and cable paper skin.
Wherein, the thickness of described cable paper internal layer is 0.03-1mm, and the thickness of described water chestnut lattice glue ply of paper is 5-10mm, and the outer field thickness of described cable paper is 0.03-1mm.Preferably, the thickness of described cable paper internal layer is 0.05mm, and the thickness of described water chestnut lattice point gummed paper is 8mm, and the outer field thickness of described cable paper is 0.05mm.
Wherein, described insulating paper layer is a gummed paper layer.
Compared with prior art, the utility model has the advantages that:
1, in described high strength rectangle winding support frame to bear internal stress strong, good stability, can be used in amorphous alloy transformer, effectively improves the anti-sudden short circuit ability of transformer, has extended the useful life of transformer.
2, in described high strength rectangle, the manufacture method of winding support frame is simple, cost is low, raw material is easy to get.

Fig. 3 is the material structure layer schematic diagram of paper web.
In figure: 1. paper web, 2. insulating paper layer, 3. Copper Foil, 11. cable paper internal layers, 12. water chestnut lattice glue ply of papers, 13. cable papers are outer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, winding support frame in a kind of high strength rectangle, is characterized in that:
Described interior winding support frame is comprised of paper web 1, insulating paper layer 2 and the Copper Foil outside insulating paper layer 23 outside paper web 1;
Described paper web 1 is comprised of cable paper internal layer 11, water chestnut lattice glue ply of paper 12 and cable paper skin 13.
Wherein, the thickness of described cable paper internal layer 11 is 0.03-1mm, and the thickness of described water chestnut lattice glue ply of paper 12 is 5-10mm, and the thickness of described cable paper skin 13 is 0.03-1mm.Preferably, the thickness of described cable paper internal layer 11 is 0.05mm, and the thickness of described water chestnut lattice glue ply of paper 12 is 8mm, and the thickness of described cable paper skin 13 is 0.05mm.
