Abstract
The utility model discloses an insulation end ring structure of a 110kV transformer coil, which comprises cushion blocks and a paper ring, wherein the paper ring is annular, and the cushion blocks are uniformly fixed on the paper ring in a circumferential direction. With the adoption of the structure that the paper ring is combined with the cushion blocks, an insulation effect of the end part of the transformer coil is exerted; the insulation end ring structure has the characteristics that materials are saved, ingredients are simplified and a technique is simple, so that the waste is reduced and working hours are saved; and the size of an insulation end ring in the structure is not large and a site is not occupied, so that various special equipments with high requirements can be used.
Description
Technical field
The utility model belongs to transformer insulated field, relates to a kind of insulating end ring structure, especially a kind of 110kV transformer coil insulating end ring structure.
Background technology
110kV transformer coil insulating end ring is made, and is to stay allowance according to external diameter in the coil, and circle is cut corresponding size paper circle, brush coating, airing.Thickness is overlapping neat, hot-forming on request with the paper circle of airing then.Because external diameter is bigger in the 110kV transformer, getting the raw materials ready needs big fabric width cardboard, and circle cuts and can produce tailing, causes very big waste, and take a lot of work, time-consuming; The general 15mm-30mm of coil insulation end circle thickness needs circle to cut several paper circles, hanger airing, occupied ground; Folded neat rear jig clamps, and needs the some anchor clamps of configuration.Remove the lacquer knurl after hot pressing finishes, the size that last car system needs also needs vertical lathe car system. and the specialized apparatus requirement is high.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of 110kV transformer coil insulating end ring structure is provided.
This insulating end ring of transformer structure solves by the following technical programs:
Comprise cushion block and paper circle; Described paper circle is toroidal, and cushion block along the circumferential direction evenly is fixed on the paper circle.
Above-mentioned cushion block is adopted in the method for paste and is fixed together with the paper circle.
The inside and outside footpath of above-mentioned paper circle equals the inside and outside footpath of transformer coil, and paper circle thickness is 2mm.
The thickness of above-mentioned cushion block is than the little 2mm of thickness of paper circle, and length equates to size with the coil width of cloth.
Above-mentioned cushion block width is identical with the inside and outside coil of transformer, is 60mm.
The utility model in the insulating effect that has played the transformer coil end, owing to characteristics such as it save material, and batching is simplified, and technology is simple, has reduced waste by with adopting paper circle and cushion block structure combining, has saved man-hour; Simultaneously because the insulating end ring size of this structure is little, also occupied ground not can use the specialized apparatus of various high requests.
Description of drawings
Fig. 1 is vertical view of the present utility model;
Fig. 2 is front view figure of the present utility model.
Wherein: 1 is cushion block; 2 is the paper circle.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1-2, this 110kV transformer coil insulating end ring structure comprises cushion block 1 and paper circle 2; Described paper circle 2 is toroidal, and cushion block 1 along the circumferential direction evenly is fixed on the paper circle 2.Cushion block 1 is adopted in the method for paste and is fixed together with paper circle 2.The inside and outside footpath of paper circle 2 equals the inside and outside footpath of transformer coil, and paper circle 2 thickness are 2mm.The thickness of cushion block 1 is than the little 2mm of thickness of paper circle 2, and length equates to size with the coil width of cloth.Cushion block 1 width is identical with the inside and outside coil of transformer, is 60mm.
Concrete manufacture method of the present utility model is:
110kV transformer coil insulating end ring improves and is designed to paper circle sticky pad block structure.According to external diameter in the coil, each end circle circle is cut a 2mm ground paper circle.Cushion block is made, and its thickness subtracts 2mm by end circle design thickness, and length is pressed the coil width of cloth to size, and the inside and outside coil of width is all identical, is 60mm.Cushion block evenly is bonded on the paper circle by the design gear.When placing the end circle, cushion block center and stay center-aligned, the insulating end ring of this structure is saved material, and batching is simplified, and technology is simple.
