Abstract
The invention discloses a high-voltage winding for an epoxy cast amorphous alloy dry-type transformer. The high-voltage winding is wound on a winding former, the high-voltage winding comprises an inner layer and an outer layer, an air channel structure is arranged between the inner layer and the outer layer, the inner layer and the outer layer respectively and sequentially comprises a glass grid cloth layer, a plurality of conductor layers and a glass grid cloth layer from inside to outside, and a conductor layer insulation DMD layer is arranged between every two adjacent conductor layers. The high-voltage winding is provided with the air channel structure, the heat dissipation efficiency of the high-voltage winding itself is greatly improved, the production cost is reduced, and the investment cost is reduced.
Description
Technical field
The present invention relates to a kind of transformer high pressure winding, be specifically related to a kind of epoxy pouring type amorphous alloy dry-type transformer high pressure winding.
Background technology
Along with the popularization of national energy-saving Huimin policy with implement, amorphous alloy transformer demand is develop rapidly, and since considering to have developed domestic the 1st 10kV amorphous alloy dry-type transformer, the dry change of amorphous approved by user gradually, and existing market demand constantly increases.
But amorphous alloy dry-type transformer fancy price and lower production efficiency become the major reason that investment cost increases greatly.
As the high pressure winding of one of epoxy pouring type amorphous alloy dry-type transformer core component, in actual production, exist winding temperature rise higher, the defect that production cost is higher.
Summary of the invention
Object of the present invention, provides a kind of epoxy pouring type amorphous alloy dry-type transformer high pressure winding exactly in order to address the above problem.
The object of the present invention is achieved like this:
A kind of epoxy pouring type amorphous alloy dry-type transformer high pressure winding of the present invention, described high pressure winding is set around on coil-winding die, described high pressure winding comprises internal layer and skin, between described internal layer and skin, be provided with air passage structure, described internal layer and skin all comprise glass grid layer of cloth, some conductor layers and glass grid layer of cloth from the inside to the outside successively, and between adjacent conductor layer, are provided with wire layer insulation DMD layer.
Above-mentioned a kind of epoxy pouring type amorphous alloy dry-type transformer high pressure winding, wherein, described air passage structure comprises that several extend the duct arranging along described high pressure winding short transverse.
Above-mentioned a kind of epoxy pouring type amorphous alloy dry-type transformer high pressure winding, wherein, the cross section of described high pressure winding is square and encircles or elliptical ring structure.
High pressure winding of the present invention is provided with air passage structure, this air passage structure has increased radiating surface and heat dissipation wind channel, increased the radiating efficiency of high pressure winding self, reduced the temperature rise of high pressure winding, in the situation that temperature rise surplus promotes greatly, can reduce high pressure winding copper cash wire gauge, reduce the consumption of wire, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, there is shown epoxy pouring type amorphous alloy dry-type transformer high pressure winding of the present invention, this high pressure winding is set around on coil-winding die 4, high pressure winding of the present invention comprises internal layer 1 and outer 2, between internal layer 1 and outer 2, be provided with air passage structure 3, air passage structure 3 comprises that several extend the duct arranging along high pressure winding short transverse.
As shown in Figure 2, internal layer 1 and outer 2 structural similarities, be all to comprise successively from the inside to the outside glass grid layer of cloth 21, some conductor layers 22 and glass grid layer of cloth 21, and between adjacent conductor layer 22, be provided with wire layer insulation DMD layer 23.
The cross section of high pressure winding of the present invention is square and encircles or elliptical ring structure.
Air passage structure 3 in the present invention has increased radiating surface and heat dissipation wind channel, has increased the radiating efficiency of high pressure winding self, has reduced the temperature rise of high pressure winding, in the situation that temperature rise surplus promotes greatly, can reduce high pressure winding copper cash wire gauge
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
