Abstract
The utility model belongs to the technical field of transformer coil winding structures, and particularly relates to a multilayer cylinder type transformer winding end coil fixing structure. The multilayer cylinder type transformer winding end coil fixing structure comprises transformer winding end coils, and is characterized in that each transformer winding end coil layer is sleeved with adhesive dispensing paper; a conventional round winding of each transformer winding end coil is provided with the adhesive dispensing paper in three to five positions along the circumference; and a rectangular or long and round winding of each transformer winding end coil is provided with the adhesive dispensing paper in one to three positions in the long and short edge directions. According to the multilayer cylinder type transformer winding end coil fixing structure, the structure is simple, the use is convenient, and after the coils are heated, the adhesive dispensing paper discharges adhesive, so that the end coils and other parts of the windings form a firm and impartible whole, and the mechanical strength of a product is improved and the service life of the product is prolonged to a great extent; and besides, the fixing structure is high in material utilization ratio and cost performance, improves the short-circuit resistance of the transformer and facilitates popularization and application.
Description
(1) technical field
The utility model relates to a kind of multi-layer cylinder formula Transformer Winding end circle fixed structure, belongs to transformer coil winding technical field of structures.
(2) background technology
Present stage, fixing of the end circle of power transformer, press-fits in process in oven dry, easily causes the loosening of end circle, even if there is layer insulation, due to end circle between end ring layer have 1～2 layer fixing, and winding process tightening force differs, and is difficult to make end circle partly to become an organic whole with stay, end encloses less than the effect of strengthening winding mechanical strength, do not tolerate sudden short circuit test, greatly reduce transformer reliability of operation, affect the useful life of transformer simultaneously.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of simple in structure, easy to use, effectively the multi-layer cylinder formula Transformer Winding end circle fixed structure of stationary transformer winding terminal circle.
The utility model is achieved by the following technical solution:
A kind of multi-layer cylinder formula Transformer Winding end circle fixed structure, comprise Transformer Winding end circle, it is characterized in that: every layer, described Transformer Winding end circle all cover has a gummed paper, the circular winding of routine of Transformer Winding end circle is equipped with a gummed paper along circumference 3-5 place, and the rectangle of Transformer Winding end circle or Long Circle winding are provided with a gummed paper at length edge direction 1-3 place.
Wherein:
The described long 100mm of some gummed paper, wide 30mm, thick 0.08mm, in the narrower situation of the some gummed paper width that uses, winding process winding between layers, point gummed paper is not easy overlap joint, in wider, the thicker situation of the some gummed paper that uses, although mechanical strength increases, overlap joint area is excessive, the number of plies is more, affect radial size, the some gummed paper stiff end circle of thick 0.08mm, toughness and oven dry plastic emitting are effective, in the middle of substituting traditional transformer winding terminal circle, do not fix, or end circle is used the fixed structure of pyrocondensation belt colligation once in a while.
Between described Transformer Winding end circle high-low pressure, be provided with stay, by stay stretching, draw reality, greatly increased fastness of the present utility model.
The beneficial effects of the utility model are: simple in structure, easy to use, after coil heats, put gummed paper plastic emitting, and make end circle become a firm indivisible integral body, mechanical strength and the useful life of having improved to a great extent product with other parts of winding; Stock utilization is high, and cost performance is high, has improved the anti-short circuit capability of transformer, easy to utilize.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the utility model structural representation.
In figure: 1, Transformer Winding end circle; 2, some gummed paper; 3, stay.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model multi-layer cylinder formula Transformer Winding end circle fixed structure as shown in Figure 1, comprise Transformer Winding end circle 1, described Transformer Winding end circle 1 every layer all cover have a gummed paper 2, the circular winding of routine of Transformer Winding end circle 1 is equipped with a gummed paper 2 along circumference 3-5 place, the rectangle of Transformer Winding end circle 1 or Long Circle winding are provided with a gummed paper 2 at length edge direction 1-3 place, between Transformer Winding end circle 1 high-low pressure, be provided with stay 3, by stay 3, compress and draw reality, greatly increased fastness of the present utility model.
The multi-layer cylinder formula winding that wire gauge was larger in the past, end encloses thickness, width is larger; The long limit of rectangle, oval winding size is large, and winding technique process end circle is all difficult to fixing, and the utility model makes end circle and other parts of winding become a firm indivisible integral body, mechanical strength and the useful life of having improved to a great extent product.
Claims (3)
