Abstract
The utility model relates to a soft angle ring of transformer, belonging to the technical field of transformers. The technical scheme is that the soft angle ring comprises a transformer iron core (1), a transformer low-voltage coil (2), a transformer high-voltage coil (3) and a soft angle ring (4), wherein the transformer low-voltage coil (2) and the transformer high-voltage coil (3) are sheathed on the transformer iron core (1), and the soft angle ring (4) is arranged between the transformer low-voltage coil and the transformer high-voltage coil. The soft angle ring (4) is made of electric insulation crinkled paper. The width of the crinkled paper is larger than the axial height of the coil and is put between the high-voltage coil and the low-voltage coil when the coil is wound. The lengths of the crinkled paper exposed out of the two ends of the oil are equal. The exposed parts are bended toward the high-voltage coil. The utility model has the advantages that the insulation distance is shortened, the structure of the transformer is more compact and the cost is saved; and the smoothness of the axial oil passage of the high-voltage coil is ensured and the heat dissipation effect is improved.
Description
Affiliated technical field:
The utility model relates to a transformer soft corner-ring, belongs to the depressor technical field.
Background technology:
In transformer is made, strengthen end field intensity branch in order to improve, strengthen overhang insulation intensity, transformer often adopts the forming paper square ring to strengthen overhang insulation, generally by the dress device fabrication of specialized factory, production technology is complicated for this moulding soft corner-ring, and cost is higher.Layer coil uses square ring can block axial oil duct, has a strong impact on radiating effect.
The utility model content:
The utility model purpose provides a kind of transformer soft corner-ring, has strengthened the creepage distance of end greatly, and balanced end field intensity has shortened insulation distance, makes transformer device structure compact more, saves cost; Guarantee the unimpeded of the axial oil duct of high-tension coil, improved radiating effect, solved the problems referred to above that exist in the background technology.
The technical solution of the utility model is: a kind of transformer comprises transformer core, low voltage winding in transformers, transformer high-voltage coil, soft corner-ring with soft corner-ring, low voltage winding in transformers and transformer high-voltage coil are enclosed within on the transformer fe stem stem, are provided with soft corner-ring in the middle of low voltage winding in transformers and transformer high-voltage coil.
Transformer soft corner-ring in above-mentioned, it uses electric insulation crimped paper to make, the width of crimped paper is greater than the axial height of coil, be placed between the high-voltage coil and low-voltage coil during coiling, crimped paper exposes coil two ends equal in length, exposed portions serve bends to high-tension coil, and the placement of soft corner-ring has promptly been finished in the bending natural perk in back.
The beneficial effects of the utility model are: shortened insulation distance, made transformer device structure compact more, saved cost; Guarantee the unimpeded of the axial oil duct of high-tension coil, improved radiating effect.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: transformer core 1, low voltage winding in transformers 2, transformer high-voltage coil 3, soft corner-ring 4.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of transformer comprises transformer core 1, low voltage winding in transformers 2, transformer high-voltage coil 3, soft corner-ring 4 with soft corner-ring, low voltage winding in transformers 2 and transformer high-voltage coil 3 are enclosed within on the transformer core 1, are provided with soft corner-ring 4 in the middle of low voltage winding in transformers 2 and transformer high-voltage coil 3.Transformer soft corner-ring in above-mentioned, it uses electric insulation crimped paper to make, the width of crimped paper is greater than the axial height of coil, be placed between the high-voltage coil and low-voltage coil during coiling, crimped paper exposes coil two ends equal in length, exposed portions serve bends to high-tension coil, and the placement of soft corner-ring has promptly been finished in the bending natural perk in back.The utility model has been strengthened the creepage distance of end greatly, and balanced end field intensity has shortened insulation distance, makes transformer device structure compact more, saves cost; Be not close to high-tension coil after the bending of electric insulation crimped paper, the bending natural perk in back has guaranteed the unimpeded of the axial oil duct of high-tension coil, has improved radiating effect.
