Abstract
The present invention relates to a kind of dispensing paper bag core structure, including iron core and coil, it is in that, provided with a point gummed paper outside winding, winding, point gummed paper is bent into U-shaped, and point gummed paper is placed between winding and iron core that coil, which is around between multiple iron cores,.The present invention has following advantages compared with prior art：Amorphous iron core overlap mechanical strength is improved, will be isolated because of the fragment that transformer with amorphous alloy made iron core is produced when bearing short circuit current flow with winding, it is to avoid the insulation of amorphous chips affect winding, prevented product from burning, increase the service life.
Description
Technical field
The present invention relates to a kind of dispensing paper bag core structure, belong to amorphous transformer technical field.
Background technology
Amorphous alloy material has unusual sensitiveness to pressure, shock and bending etc..After being under pressure, hitting and bending
Its open circuit loss increase, while being easy to appearance is broken and produces fragment.Transformer with amorphous alloy made iron core is bearing short circuit current flow
When, the axial force that the stray field width of rectangle winding is produced to component makes winding bear the effect of pressure or pulling force.Direction of pull is
To poor iron yoke.When pulling force is more than the mechanical strength of each structural member, just change can be produced by the part such as rectangle winding, pressing plate and folder
Shape, by the drawing crack of amorphous alloy iron core lap-joint and fragment can be produced when serious.Amorphous fragment easily trigger winding layer short circuit or around
Group shorted to earth, ultimately results in product and burns.
Therefore, it should a kind of new technical scheme is provided and solved the above problems.
The content of the invention
The present invention provides a kind of dispensing paper bag core structure.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of dispensing paper bag core structure, including iron core and coil, it is in outside winding, winding that coil, which is around between multiple iron cores,
Portion provided with point a gummed paper, point gummed paper be bent into it is U-shaped, point gummed paper be placed between winding and iron core.
The relevant content of above-mentioned technical proposal is explained as follows：
In above-mentioned technical proposal, point gummed paper uses double spread.
Further technical scheme, before amorphous iron core overlap is closed, winding and iron core are placed on by point gummed paper above
Between, after the completion of closing, point gummed paper bending is completely covered amorphous iron core overlap and fixed with 3M adhesive tapes.
It is preferred that, extension is provided between point gummed paper two ends and winding.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
Amorphous iron core overlap mechanical strength is improved, will be produced because of transformer with amorphous alloy made iron core when bearing short circuit current flow
Fragment isolate with winding, it is to avoid the insulation of amorphous chips affect winding, prevent product from burning, increase the service life, it is effectively anti-
Only amorphous fragment leaks, and improves transformer station high-voltage side bus security.
Brief description of the drawings
Accompanying drawing 1 is existing schematic diagram.
Accompanying drawing 2 is schematic diagram of the present invention.
In the figures above：1st, iron core；2nd, coil；3rd, gummed paper is put；4th, extension；5th, amorphous iron core overlap.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
As illustrated in fig. 1 and 2, a kind of dispensing paper bag core structure of the invention, including iron core 1 and coil 2, coil 2 is around in
Be in winding between multiple iron cores 1, provided with a point gummed paper 3 outside winding, point gummed paper 3 uses double spread, point gummed paper 3 be bent into it is U-shaped,
Point gummed paper 3 is placed between winding and iron core 1, extension 4 is provided between the point two ends of gummed paper 3 and winding, in amorphous iron core overlap 5
Before closing, point gummed paper 3 above is placed between winding and iron core 1, after the completion of closing, amorphous is completely covered in the point bending of gummed paper 3
Iron core overlap 5 is simultaneously fixed with 3M adhesive tapes, is improved amorphous iron core overlap mechanical strength, will be existed because of transformer with amorphous alloy made iron core
The fragment for bearing to produce during short circuit current flow is isolated with winding, it is to avoid the insulation of amorphous chips affect winding, is prevented product from burning, is prolonged
Long life.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all be included within the scope of the present invention.
