An iron core comprises a plurality of parallel frame-like amorphous alloys; and high and low voltage windings are respectively made of aluminum conductor materials. According to the utility model, the heat radiating property of the iron core can be effectively improved and the cost of the transformer can be greatly reduced; and compared with a common oil immersed transformer, the low-loss amorphous alloy oil immersed power transformer with the aluminum windings, disclosed by the utility model, has the advantages of low temperature rise, slow ageing, large overload capability and long service life.
Description
Technical field
The utility model relates to field transformer, is specially a kind of non-crystaline amorphous metal aluminium winding low-loss oil immersed power transformer.
Background technology
In the prior art by iron core, the transformer that winding, shell etc. are formed, amorphous iron core weight is heavier, consumptive material is more, cost is high, weak heat-dissipating.The copper metal material that winding adopts because the copper valency is high many with the amorphous iron core consumptive material, causes the transformer cost high, and user's financial burden is heavy.
The utility model content
The utility model purpose provides a kind of non-crystaline amorphous metal aluminium winding low-loss oil immersed power transformer, and is high to solve prior art transformer cost, the problem of weak heat-dissipating.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of non-crystaline amorphous metal aluminium winding low-loss oil immersed power transformer; Include the iron core that places the fuel tank oil sealing; And be wrapped in the high and low pressure winding on the iron core, and it is characterized in that: said iron core is made up of the non-crystaline amorphous metal frame of a plurality of frame shapes side by side, and each non-crystaline amorphous metal frame is formed around folded by the multilayer amorphous alloy strip; Said high and low pressure winding is processed by the aluminium conductor material respectively, and the high and low pressure winding is wrapped in respectively on the frame post of amorphous iron core frame.
Described a kind of non-crystaline amorphous metal aluminium winding low-loss oil immersed power transformer; The three-phase three-column, the three-phase and five-pole amorphous iron core that adopt many frames to form side by side; It is characterized in that: two or more three-phase three-columns, three-phase and five-pole iron core file are overlapping; Reach and enhance product performance, reduce amorphous iron core weight.
Described a kind of non-crystaline amorphous metal aluminium winding low-loss oil immersed power transformer, high and low pressure adopts the aluminium conductor winding, and it is characterized in that: the unit price of aluminium is low, and is in light weight, and equal resistor current density is little, and temperature rise is low, and ageing of insulation is slow, and the life-span is long, and cost is low.
The utility model iron core adopts the amorphous iron core of many frames high permeability amorphous alloy strip formation arranged side by side, can effectively improve the thermal diffusivity of iron core, reduces the consumption of non-crystaline amorphous metal, reduces transformer loss.The high and low pressure winding adopts the aluminium conductor material to process respectively, and the transformer cost is reduced greatly.The utility model no-load loss reduces by 65% ~ 75% than mill run, and cost descends 20 ~ 30%, compares with common oil-immersed type transformer, and temperature rise is low, and aging slow, overload capacity is big, long service life.
