Description
Technical field
The utility model relates to a kind of resin-insulated dry distribution transformer, particularly relates to a kind of resin-insulated dry aluminium conductor amorphous alloy distribution transformer.
Background technology
As everyone knows, dry-type distribution transformer mainly is that iron core, coil and various annex are formed, and iron core and coil are to influence the topmost parts of transformer performance.At present, known dry-type transformer mainly adopts the cold rolled silicon steel iron core, and no-load loss is bigger.For reducing no-load loss, some producers substitute the cold rolled silicon steel iron core with amorphous alloy core, but the amorphous core price is higher than the silicon steel iron core, and the close silicon steel iron core that is significantly less than of magnetic especially allowable makes the amorphous transformer cost increase greatly, does not meet the economic benefit requirement; And because the amorphous transformer coil is generally square, discontinuity during sudden short circuit, coil ftractures easily during sudden short circuit.Therefore, the transformer adopting amorphous alloy core must will guarantee the mechanical strength of coil when reducing cost, and could make that like this transformer noload losses is little and mechanical strength is big.The electromagnetic wire common conductor material of transformer is copper and aluminium, and aluminum steel (or aluminium foil) mechanical strength is relatively poor, so the amorphous transformer coil all still adopts copper cash (or Copper Foil) coiling; The cost of copper far exceeds aluminium, if can adopt aluminum steel (or aluminium foil) as electric conducting material, then can be implemented in when reducing no-load loss and does not increase the transformer manufacturing cost.But the mechanical strength of aluminium is hanged down and has been limited its application on amorphous alloy distribution transformer.
Summary of the invention
The purpose of this utility model provides a kind of resin-insulated dry distribution transformer, and a kind of resin-insulated dry aluminium conductor amorphous alloy distribution transformer particularly is provided.The utility model has solved big, the relatively poor problem of Amorphous Alloy Core Transformer coil mechanical strength of cold rolled silicon steel iron-core transformer no-load loss, has remedied the deficiency that prior art causes cost significantly to increase easily
In order to reduce the no-load loss of transformer, do not increase the cost of transformer again, the utility model adopts aluminum steel or aluminium foil as electric conducting material, adopt non-crystaline amorphous metal as permeability magnetic material, this transformer not only makes no-load loss compare with the silicon steel iron-core transformer to have descended more than 70%, and cost is close with it.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of resin-insulated dry aluminium conductor amorphous alloy distribution transformer, contain folder, amorphous alloy core, high-tension coil, low-voltage coil, it is characterized in that: high-tension coil and low-voltage coil all are to adopt the aluminium conductor coiling, high-tension coil and low-voltage coil all also have liner and periphery, surface, high-tension coil and the liner of liner and periphery, space, low-voltage coil and liner between the periphery, the space between the periphery all are filled with epoxy resin, high-tension coil and liner and the peripheral one that forms after solidifying, low-voltage coil and liner and the peripheral one that forms.
Described liner is that enhancement mode fiberglass gridding and fiberglass braided band coincide and form.
Described periphery is that enhancement mode fiberglass gridding and fiberglass braided band coincide and form.
Described aluminium conductor is aluminum steel or aluminium foil.
The beneficial effects of the utility model are:
Can not increase the manufacturing cost of transformer again when significantly reducing transformer noload losses, no-load loss is compared with the silicon steel iron-core transformer and has been descended more than 70%; Coil integral body is very firm, have sizable radially with axial mechanical strength, thereby remedied the relatively poor shortcoming of aluminium mechanical strength, improved the ability of the anti-sudden short circuit of coil.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Embodiment 1
The structure of the structure of present embodiment and resin-insulated dry aluminum steel amorphous alloy distribution transformer shown in Figure 1 is identical.
In the embodiment shown in fig. 1, high-tension coil 7 adopts aluminium foils 2 coilings, and high-tension coil 7 has liner and periphery, liner and peripheral all by enhancement mode fiberglass gridding 4 with fiberglass braidedly be with 5 to coincide and form.Adopt 3 pairs of high-tension coils of epoxy resin 7 and liner and peripheral cast, high-tension coil and liner and the peripheral one that forms after solidifying.
Low-voltage coil 6 adopts aluminium foils 2 coilings, and low-voltage coil 6 has liner and periphery, liner and peripheral all by enhancement mode fiberglass gridding 4 with fiberglass braidedly be with 5 to coincide and form.Adopt 3 pairs of low-voltage coils of epoxy resin 6 and liner and peripheral cast, low-voltage coil 6 and liner and the peripheral one that forms after solidifying.
