Abstract
The utility model discloses a clamp of a three-dimensional transformer with wound core, which is composed of an upper clamp and a lower clamp and a screw which is connected between the two clamps. The upper clamp and the lower clamp are both composed of a web, a roof, and an end-plate in an opposite direction. The web, the roof and the end-plate are welded in to a structure of a regular triangle inside and a hexagon outside, and the web is aligned with an angle 120 degrees to the end-plate, and the roof is vertical interconnected with the web and the end-plate. The web is welded with a channel steel for the upper clamp and the lower clamp pull through the screw. The web and the end-plate are welded with a small channel steel, and the roof is welded a regular triangle support in a side. The utility model has the functions of the conventional clamp, and can cover the entire iron core from up to down to prevent from suffering external force, more particularly to the protection of the annealing three-dimensional transformer with the wound core, the support of the coil, and the bearing of the transformer. The utility has the advantages of solving the problem of uneven distribution of the pressing force in the coil of the three-dimensional transformer with the wound core, improving the ability of resisting axial electrodynamic force when the transformer with a sudden short circuit, and reducing the no-load loss and the noise.
Description
Technical field
The utility model relates to a kind of transformer folder, relates in particular to a kind of three-dimensional rolled iron core transformer folder, belongs to electrical equipment technical field.
Background technology
After three-dimensional rolled iron core (claiming that again the triangle volume is unshakable in one's determination) is annealed, not only eliminates machining stress unshakable in one's determination, and made the redistribution of silicon steel sheet crystal orientation, reduced no-load loss unshakable in one's determination and noise.The transformer that the employing three-dimensional rolled iron core is produced is dry-type transformer particularly, all may cause stress to iron core in manufacturing, transportation, carrying, installation process, thereby causes no-load loss unshakable in one's determination, noise to increase.Traditional channel-section steel formula folder can't protect iron core to avoid external stress fully.
Summary of the invention
The purpose of this utility model is: be for solve the three-dimensional rolled iron core transformer particularly the iron core of dry-type transformer in the manufacturing of transformer, transportation, carrying, installation process, avoid or reduce the problem of stress, thereby reach the purpose that reduces no-load loss unshakable in one's determination and noise.
The utility model is realized by following scheme: be made of upper and lower folder and the screw rod that is connected between the two.Upper and lower folder constitutes by web, top board, end plate, and it is opposite that direction is set, the outer hexagonal monolithic construction of positive triangle in web, top board, end plate are welded into, web and end plate are mutually 120 °, top board is vertical with web and end plate, be welded with on the web channel-section steel be used for folder from top to bottom by screw rod to drawing, web and end plate are welded with channel bar, are used for the briquetting that supporting bolt compresses end winding.
Be welded with the equilateral triangle support in the top board described in the utility model, be used to support that screw rod compresses the unshakable in one's determination inner briquetting of end winding.
One is long and the other is short is arranged in order by length on positive triangle outer hexagonal adjacent both sides in web described in the utility model, top board, end plate were welded into.
3-6 suspension ring are installed or be welded with to symmetry on the top board of upper clamping piece described in the utility model.
Be welded with 3-10 double-screw bolt on the top board of lower clamping piece described in the utility model.
The utility model not only has the function of conventional folder, and whole iron core can be covered protection up and down and be not subjected to the external force effect, is specially adapted to protection and the supporting of coil and the load-bearing of whole transformer of the three-dimensional rolled iron core after the annealed processing.By regulating hold-down bolt or the screw rod on the folder support plate, compress the briquetting of dividing equally at end winding, can also reach the purpose that compresses coil.This coil compressing structure has solved the coil thrust problem pockety of three-dimensional rolled iron core (claiming that again the triangle volume is unshakable in one's determination) transformer, can guarantee briquetting in the thrust of end winding by 4 equal distribution such as branch such as grade, anti-axial electrodynamic ability when having improved the transformer sudden short circuit, also solved the three-dimensional rolled iron core transformer particularly the iron core of dry-type transformer in the manufacturing of transformer, transportation, carrying, avoid or reduce the problem of stress in the installation process, thereby reach the purpose that reduces no-load loss unshakable in one's determination and noise and simple in structure, convenient and practical, cost is low, safe and reliable, effective.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Embodiment
Contrasting accompanying drawing below in conjunction with embodiment is elaborated to the utility model.
Embodiment:
Referring to Fig. 1, present embodiment is made of upper and lower folder 7,8 and the screw rod 9 that is connected between the two.Upper and lower folder constitutes by web 1, top board 5, end plate 6, and it is opposite that direction is set.The outer hexagonal monolithic construction of positive triangle in web 1, top board 5, end plate 6 are welded into, two adjacent edge lengths are arranged in order by one is long and the other is short.Web 1 is mutually 120 ° with end plate 2, and top board 5 is vertical with web 1 and end plate 6, be welded with on the web 1 channel-section steel 3 be used for folder from top to bottom by screw rod to drawing, web 1 and end plate 6 are welded with channel bar 2, are used for the briquetting that supporting bolt compresses end winding.Be welded with equilateral triangle support 4 in the top board 5, be used to support that screw rod compresses the unshakable in one's determination inner briquetting of end winding.Symmetry is installed or is welded with 3 suspension ring 10 on the top board 5 of upper clamping piece 7, is welded with 3 double-screw bolts 11 on the top board 5 of lower clamping piece 8.
When the utility model integral type folder is installed on transformer, lower clamping piece is fixed on the pad pin, lower clamping piece inside is lined with buffering silicon rubber, again transformer body is hung in the lower clamping piece, cover is gone up upper clamping piece then, the bolt that will be installed on the folder from top to bottom belly is tightened respectively, holds out against iron core, the folder from top to bottom Screw arbor with nut at both-ends is tightened again.Tighten the clamping screw that hold-down bolt that the channel-section steel 2 on the upper clamping piece supported and equilateral triangle support 10 are supported, compress coil, loose iron core all drops on the lower clamping piece weight of coil and iron core does not stress, and folder from top to bottom protects iron core to avoid external force.
