Background technology
Amorphous transformer core section is rectangle, and corresponding high-low pressure winding can only also use rectangle.Rectangle winding is relative
Anti-short circuit capability is poor for circular winding.When amorphous transformer bears short circuit current, axial leakage field is subject to interior winding
Inside compression stress.To improve the anti-short circuit capability of amorphous transformer, interior winding inner side must have the support of sufficient intensity.Industry
The Normal practice of producer is the insulating paper cylinder made using insulating board, when amorphous transformer bears short circuit current, its intensity
It is limited, usually cause to deform and damage because of the inside compression stress that interior winding bears.
Therefore, it should a kind of new technical scheme is provided and is solved the above problems.
The content of the invention
The present invention provides a kind of built-in epoxy cylinder of amorphous transformer coil, and its purpose is：Insulating cylinder on the inside of interior winding has
The support of sufficient intensity, it is ensured that transformer when short circuit current is born, the inside unlikely deformation of compression stress born on interior winding
Or damage.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of built-in epoxy cylinder of amorphous transformer coil, including epoxy cylinder cylinder, low-voltage line is surrounded with outside epoxy cylinder cylinder
Ring layer, low-voltage line ring layer periphery is wound with high-voltage line ring layer, and epoxy cylinder cylinder is generally rectangular configuration, and epoxy cylinder cylinder uses epoxy
Glass fiber coiling is formed.
The relevant content of above-mentioned technical proposal is explained as follows：
In above-mentioned technical proposal, epoxy cylinder drum surface is to being externally provided with arc surface.
Further technical scheme, epoxy cylinder cylinder middle setting has steel plate, and steel plate both sides are wound with epoxy fibreglass.
Preferably, epoxy cylinder drum surface has steel plate, steel plate both sides to arc surface, epoxy cylinder cylinder middle setting is externally provided with
Wound with epoxy fibreglass.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
Amorphous transformer can be offset and bear compression stress inside during short circuit, effectively improve the intensity of epoxy cylinder, it is ensured that interior
The winding compression stress inside when short circuit current is born does not cause interior winding to be deformed inward or damage.
