Abstract
Height overflows paper tinsel around dry -type transformer winding, characterized by: be provided with two independent paper tinsels on this transformer around the winding, two independent paper tinsels be provided with the insulating layer around every layer of paper tinsel of winding between, it is two sets of terminals of radial connection on the transformer that two independent paper tinsels saying wind the winding, every group terminal includes respectively and is x2 terminal, a2 terminal, a1 terminal, x1 terminal respectively by two independent terminals, the a1 terminal be connected with the a2 terminal and draw public terminal, the x1 terminal is connected with the x2 terminal and is drawn public terminal, forms required winding. The beneficial effects of the utility model are that: reasonable in design, compact structure, convenient operation, production efficiency is high, winds the winding owing to set up two independent paper tinsels, and just two independent paper tinsels wind and all have insulating being separated by between every layer of paper tinsel of winding, so eddy current loss can be reduced effectively, the load loss of transformer is reduced to make the transformer temperature rise reduce, guarantee the safe operation of transformer.
Description
Technical field
The utility model relates to converting equipment field, particularly relates to a kind of high overcurrent paper tinsel around dry-type transformer winding.
Background technology
Producing, carry, distribute and using in the whole electric power system of electric energy, transformer is very important equipment, and along with the continuous expansion of power transmission scope, the capacity of transformer also constantly increases, and causes the rated current of low pressure winding also larger.Transformer is by traditional method, and low-voltage coil has two kinds of frame modes, and first kind of way adopts multiple conducting wires to compose in parallel, and when transformer runs, winding is in the stray field of alternation, and incomplete transposition can increase sharply making circulation loss; The second way adopts paper tinsel when winding, and the eddy current loss that axial leakage field causes is relevant with the thickness of conductor, and thickness doubles, and eddy current loss increases by four times, and the increase of eddy current loss can cause increase in temperature, affects the safe operation of transformer.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of reasonable in design, and technique is simple, easy to operate, meets the high overcurrent paper tinsel of the service requirement of the transformer of low-voltage and high-current around dry-type transformer winding.
High overcurrent paper tinsel described in the utility model is around dry-type transformer winding, it is characterized in that: this transformer is provided with two independently paper tinsel around winding, described two independently paper tinsel between every layer of paper tinsel of winding, be provided with insulating barrier, said two independently paper tinsel be two groups of terminals of connection radial on the transformer around winding, often organize terminal and comprise two independent terminals respectively, be respectively x
