Description
Technical field
The utility model relates to a kind of folder devices of dry-type transformer.
Background technique
It is well known that traditional dry type transformer clamp generallys use channel steel production, supporting plate is welded in inside, and pulling plate is to use
Stiffening plate is welded at band steel production, both ends, through both weld one section of round steel and become pin, folder is by being welded on pulling plate when assembly
Pin couples the body skeleton to form transformer.When covering low-voltage coil, coil is easy to encounter pin this structure, makes low-voltage line
Snare dress is inconvenient.It is inadequate additionally, due to the folder intensity of this channel steel structure, therefore will also be on the upper edge of forward and backward folder under
Along two pieces of stiffening plates of welding, and two longitudinal ties of connection between stiffening plate are intended to, not only increase components, which will also increase, adds
Work process, the shape of transformer is also unsightly.
Utility model content
A kind of folder device of dry-type transformer is provided the purpose of the utility model is to overcome the defect of the prior art,
Its simple, save the cost with structure, and facilitate the characteristics of being set with low-voltage coil.
Purpose of the utility model is realized as follows: a kind of folder device of dry-type transformer, including preceding upper clamping piece, after
Upper clamping piece, preceding lower clamping piece, rear lower clamping piece and six roots of sensation pulling plate；Wherein,
The preceding upper clamping piece, rear upper clamping piece, preceding lower clamping piece, rear lower clamping piece are all made of square tube production；Preceding upper clamping piece, rear upper folder
Part, preceding lower clamping piece, rear lower clamping piece medial surface on respectively open up three and the center line of three iron core columns limits correspondingly
Hole；
The upper and lower end of six roots of sensation pulling plate respectively opens up a location hole；The upper and lower end of three pulling plates is drawn each by one
Plate pin connection corresponds on preceding upper clamping piece and preceding lower clamping piece and with the center line of three iron core columns；Other three pulling plates
Upper and lower end also each by a pulling plate pin connection on rear upper clamping piece and rear lower clamping piece and with the center line of three iron core columns one by one
It is corresponding；
The pulling plate pin has the plunger of large diameter cylinder type and the small-diameter circular of the coaxially connected one end in plunger of one
Cylindrical shank is simultaneously process by a round steel, and the height of shank is greater than the height of plunger；
The plunger of each pulling plate pin is embedded in the positioning hole on pulling plate, and shank is embedded in preceding upper clamping piece, rear upper clamping piece, preceding
In limit hole on lower clamping piece, rear lower clamping piece.
The folder device of above-mentioned dry-type transformer, wherein the height of the plunger of the pulling plate pin and the thickness of the pulling plate
Degree adaptation；The height of the shank is at least twice of wall thickness of the square tube.
The folder device of the dry-type transformer of the utility model has the following characteristics that
1) folder is made using square tube, so that the intensity of folder greatly increases, not only can remove reinforcing armature, saves material
Material, moreover it is possible to keep the appearance of transformer more succinct；
2) by improving the connection structure of pulling plate and folder, i.e., pulling plate pin is not welded with pulling plate, but in low-voltage coil
After packing into iron core column, by the plunger of pulling plate pin in the location hole of pulling plate, the limit hole of folder is covered into the shank in pulling plate pin
On, this structure changes the defect of the pulling plate structure suit coil inconvenience of traditional dry-type transformer, can facilitate suit
Coil, and the structure without changing transformer save cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the folder device of the dry-type transformer of the utility model；
Fig. 2 is the A-A direction view in Fig. 1；
Fig. 3 is the structural schematic diagram of the pulling plate pin in the folder device of the dry-type transformer of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
It please refers to Fig.1 to Fig.3, the folder device of the dry-type transformer of the utility model, including preceding upper clamping piece 11, rear upper folder
Part 12, preceding lower clamping piece 11 ', rear lower clamping piece and six roots of sensation pulling plate 2；Wherein,
Preceding upper clamping piece 11, rear upper clamping piece 12, preceding lower clamping piece 11 ' and rear lower clamping piece are all made of square tube production；Preceding upper clamping piece 11,
The center line one of three with three iron core columns 3 are respectively opened up on the medial surface of upper clamping piece 12, preceding lower clamping piece 11 ' and rear lower clamping piece afterwards
One corresponding limit hole 10；
The upper and lower end of six roots of sensation pulling plate 2 respectively opens up a location hole；
The upper and lower end of three pulling plates 2 is connected on preceding upper clamping piece 11 and preceding lower clamping piece 11 ' simultaneously each by a pulling plate pin 4
It is corresponded with the center line of three iron core columns 3；The upper and lower end of other three pulling plates 2 is also connected to each by a pulling plate pin 4
