Abstract
The utility model discloses a longitudinal multi-airway coil of a dry transformer. The coil is of multi-layer cylinder continuous type. The utility model is evenly divided into coil layers of even number of continuous coiling of n segments and n is an odd number which is not smaller than 3. Both sides of the coil layers of even number are provided with n layer and n level step type insulating material of central symmetric structure and equal height to the coil. In addition, except that no longitudinal airway is not arranged between outermost three layers of coils, the longitudinal airway is arranged between two spacing layers of coils. The utility model overcomes the defects of complicated technology for the coiling of the conventional dry transformer coil, large coil volume, poor dissipating heat condition, poor moisture protection, poor dust prevention, and poor flashover pollution property. The utility model has advantages of simple coiling technology, even electric field distribution, good dissipating heat condition, high insulating heat-proof gradation, environmental protection, moisture protection, good flashover pollution property, etc.
Description
Technical field
The utility model relates to the vertical many air flues coil of a kind of dry-type transformer.
Background technology
At present, traditional dry-type transformer coil all adopts two kinds of encapsulated type (subsection cylindrical formula) or non-sealing (open type).Sealing coil is solid insulation, and the non-coil of sealing is a gas-insulated.Encapsulated type exists the complicated pouring technology of technique for coiling to handle trouble, the not environmental protection of casting insulated material, shortcoming such as winding volume is big, and radiating condition is poor, and the insulation thermal endurance class is low.Also there are weak points such as protection against the tide, dustproof, anti-pollution flashover ability in non-encapsulated type.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of improved dry-type transformer between encapsulated type and non-encapsulated type vertical many air flues coil.It has concurrently seals and the non-insulation characteristics of sealing coil, the compound inslation technology that to be solid merge mutually with gas.
The technical solution of the utility model is such: coil adopts the multi-layer cylinder continous way, the even level coil is divided into the coiling continuously of n (odd numbers of n 〉=3) section, and in even level coil both sides each is provided with the n layer n level staged insulating material of the structure that is centrosymmetric, in addition, coil direction from the inside to surface, between outermost three layer line circles, do not establish vertical air flue, between two-layer coil, be equipped with vertical air flue.
After adopting such scheme, make that transformer coil winding technology is simpler, Electric Field Distribution is even, and the natural heat dissipation condition is good, insulation thermal endurance class height, environmental protection, protection against the tide, dustproof, anti-fouling flashover performance is good.
Description of drawings
Fig. 1 cuts open structural map for office of the present utility model.
Fig. 2 is the cross-sectional configurations figure of Fig. 1.
Among the figure: 1, coil 2, staged insulating material 3, vertical air flue 4, air flue stay
5, insulating material
Embodiment
With reference to Fig. 1, Fig. 2, be seven with the coil number of plies, three layers of three grades of staged insulating material are set between coil, it is example (at this n=3) that the even level coil is divided into three sections continuous coilings.
After the intact the inside of coiling ground floor is odd-level coil (1), just be provided with and the contour three layers three grades staged insulating material (2) of coil near odd-level coil right side, and major part is last, the microcephaly is following, gradin is towards the right side, corresponding then three layers of three grades of staged insulating material, divide three sections continuous coiling even levels (being the second layer) coil,, place three layers three grades staged insulating material (2) on even level coil right side around finishing, and major part is following, the microcephaly is last, and gradin is put upside down with the above-below direction in even level coil left side towards a left side, gradin is towards on the contrary, and structure is centrosymmetric.Vertical air flue (3) then is set, and after placing air flue stay (4), coiling is the odd-level coil for the 3rd layer.Then continuation around to the even level layer 6, after the staged insulating material is placed on the layer 6 right side, is not provided with air flue as stated above, and then around intact layer 7, and wraps insulating material (5) outside layer 7.
Claims (2)
1, the vertical many air flues coil of a kind of dry-type transformer, it comprises coil (1), staged insulating material (2), vertical air flue (3), air flue stay (4), it is characterized in that: coil is the multi-layer cylinder continous way, it has the even level coil (1) that is divided into the continuous coiling of n (odd numbers of n 〉=3) section, respectively be provided with the n layer n level staged insulating material (2) of and be centrosymmetric structure contour with coil in even level coil both sides, in addition, between outermost three layer line circles, do not establish vertical air flue (3), between two-layer coil, be equipped with vertical air flue (3).
2, the vertical many air flues coil of dry-type transformer according to claim 1, staged insulating material (2) major part that it is characterized in that the setting of even level coil (1) left side is last, the microcephaly is following, gradin is towards the right side, the staged insulating material that is provided with on even level coil right side and the above-below direction in left side are put upside down, gradin is towards on the contrary, and structure is centrosymmetric.
