Description
Technical field
The utility model relates to a kind of stay support constructions of transformer air-cooled formula coil, belong to transformer technology field.
Background technique
Currently, the air-cooled coil of large-scale power transformer uses cake formula structure, and the radial width of line cake is different, line
The upper and lower ends of cake be required to place end circle, effective cooling of coil, be extend the insulating materials service life, improve transformer station high-voltage side bus can
By the important means of property.Prior art the problem is that: unreasonable structure, heat dissipation performance is poor, not in place causes due to radiating
The phenomenon that transformer breaks down because of high temperature, has shortened the service life of transformer.
Utility model content
The utility model aim is to provide a kind of stay support construction of transformer air-cooled formula coil, and radial width is enclosed at end
Reduce, the width of reduction is replaced with collets, and collets and stay are bonded together, and can form bigger wind in this way
Road when transformer works normally, hot wind is discharged enough and uses, reduces the temperature of coil, ensure that the performance of transformer, solve
The above problem present in background technique.
The technical solution of the utility model is:
A kind of stay support construction of transformer air-cooled formula coil includes insulating cylinder, coil, upper end circle and lower end turn, line
Circle is arranged outside insulating cylinder, and the upper end of coil is enclosed equipped with upper end, on the excircle that lower end is enclosed equipped with lower end turn, the upper end uniformly
It arranges multiple upper collets, multiple lower collets is evenly arranged on the excircle of lower end turn, upper end circle is plus after upper collets
Whole radial width is radial of same size plus the entirety after lower collets with lower end turn, is all larger than the radial width of coil；On
Collets are equal with lower insulation number of blocks, correspond to each other arrangement；Be equipped with stay between upper collets and lower collets, stay it is outer
Face is equipped with ventilating duct.
The both ends of the stay are respectively adhered on collets and lower collets, and insulating paper formation is wrapped with outside stay and is led
Air duct.
The coil uses cake formula structure, including the line cake one, line cake two and line cake three arranged from the top down, line cake one,
The radial width of line cake two and line cake three is not identical, and the radial width of line cake two is maximum；The radial width of upper end circle or lower end turn
Less than the radial width of line cake two, upper end circle or lower end turn add the radial width of entirety after collets or lower collets respectively
Degree, greater than the radial width of line cake two.
The beneficial effects of the utility model are: the radial width of upper and lower side circle is reduced, the width of reduction is used up and down absolutely respectively
Edge block replaces, and upper and lower collets are bonded together with stay, can form bigger air duct in this way, and transformer works normally
When, hot wind is discharged enough and uses, reduces the temperature of coil, ensure that the performance of transformer.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model (no ventilating duct)；
Fig. 2 is the utility model overlooking structure diagram；
In figure: 5, lower end turn 6, upper collets 7, lower insulation are enclosed in insulating cylinder 1, line cake 1, line cake 23, line cake 34, upper end
Block 8, stay 9, ventilating duct 10.
Specific embodiment
Below in conjunction with attached drawing, the utility model is further described by embodiment.
A kind of stay support construction of transformer air-cooled formula coil encloses 5 and lower end turn 6 comprising insulating cylinder 1, coil, upper end,
Coil is arranged outside insulating cylinder 1, and the upper end of coil is equipped with upper end circle 5, and lower end is equipped with lower end turn 6, the excircle of the upper end circle 5
On be evenly arranged multiple upper collets 7, be evenly arranged multiple lower collets 8 on the excircle of lower end turn 6, upper end circle 5 is plus upper
The radial width of entirety after collets 7 is radial of same size plus the entirety after lower collets 8 with lower end turn 6, is all larger than coil
Radial width；Upper collets 7 are equal with lower 8 quantity of collets, correspond to each other arrangement；Between upper collets 7 and lower collets 8
Equipped with stay 9, the outside of stay 9 is equipped with ventilating duct 10.
The both ends of the stay 9 are respectively adhered on collets 7 and lower collets 8, and insulating paper shape is wrapped with outside stay 9
At ventilating duct 10.
The coil uses cake formula structure, including the line cake 1, line cake 23 and line cake 34 arranged from the top down, line cake
One 2, the radial width of line cake 23 and line cake 34 is not identical, and the radial width of line cake 23 is maximum；Upper end circle 5 or lower end turn 6
Radial width is less than the radial width of line cake 23, after upper end circle 5 or lower end turn 6 add upper collets 7 or lower collets 8 respectively
The radial width of entirety, greater than the radial width of line cake 23.
The upper end circle and lower end turn are connect with insulating cylinder 1 respectively, and upper collets and lower collets are respectively adhered on upper end
On circle and lower end turn excircle.
The utility model can form bigger air duct, when transformer works normally, hot wind is discharged enough and uses, reduces
The temperature of coil ensure that the performance of transformer.
