Description
Technical field
The utility model belongs to transformer manufacture technology, relates to a kind of for the oval coil in distribution transformer.
Background technology
Traditional transformer coil is based on circular configuration always, and along with the progress of design concept, the raising of technological level and the needs of Energy Saving Product Design, distribution transformer coils is progressively toward the transition of Long Circle coil.Circular configuration coil mechanical strength is better, and anti-short circuit capability is comparatively strong, and coil shape size ratio is easier to control, and along with the raising of design performance parameter, required material is that multiple increases, and is unfavorable for the material-saving of product.Long Circle structure coil is then contrary, and loop construction mechanical strength is weaker, and anti-short circuit capability is poor, the overall dimension of coiling finished product is also not easy to control, virtually add the consumption of main material, but classical insulation design is easier to ensure, material therefor is also comparatively saved.
Summary of the invention
The purpose of this utility model is to provide a kind of oval coil, this ellipse forms coil and has been combined the high advantage of saving material with oval coil of circle core configuration intensity, drastically increase operation week transfer efficient, shorten the production cycle of product, save the energy needed for coil drying, save raw material.
The purpose of this utility model is achieved through the following technical solutions:
A kind of oval coil, it is characterized in that: this oval coil comprises high-tension coil in complete elliptical shape and low-voltage coil, the curtain oil duct forming main insulation is provided with between high-tension coil and low-voltage coil, this curtain oil duct is bonded on cardboard by stay and forms, and the side of stay is towards low-voltage coil; Outside high-tension coil, be positioned at A, C phase is respectively wound with corrugated board; One and half oil ducts are provided with in high-tension coil inside.
In the utility model, corrugated board mainly plays the insulating effect between coil and fuel tank, can reduce the safe distance between coil and fuel tank thus.High-voltage coil and low-voltage coil inside arranges half oil duct of right quantity as required, the quantity of one and half oil ducts and the temperature rise of coil suitable, the quantity of half oil duct according to the temperature rise situation of coil through Row sum-equal matrix.One and half oil ducts are evenly arranged at high-tension coil inner.The stay that half oil duct is not waited by thickness is bonded on cable paper and forms.
The utility model is a kind of brand-new oval structure coil and insulation system thereof.The technical characteristics of this structure is: high-voltage coil and low-voltage coil is all in complete elliptical shape, and the main insulation between high-voltage coil and low-voltage coil is made up of curtain oil duct, and curtain oil duct is bonded on cardboard by stay and forms, and during coiling, stay side is to low-voltage coil, to be more conducive to heat radiation.Respectively be wound around a corrugated board in the outside of A, C phase coil after coil winding completes, corrugated board mainly plays the insulating effect between coil and fuel tank, can reduce the safe distance between coil and fuel tank thus.
Advantage of the present utility model is: oval structure coil has been combined the high advantage of saving material with oval coil of circle core configuration intensity.After coil winding completes, overall dimension can be effectively controlled, and eliminates the operation of suppressing drying after oval coil winding completes simultaneously, drastically increases operation week transfer efficient, shorten the production cycle of product, saved the energy needed for coil drying.Meanwhile, the actual use amount of material have also been obtained effective guarantee, has saved raw material.On the basis of great number tested data, during loop construction design, fully take into account the needs of heat radiation and electric property, met performance index requirement.

Embodiment
A kind of oval coil, see shown in accompanying drawing, this oval coil comprises high-tension coil 1 in complete elliptical shape and low-voltage coil 2, the curtain oil duct 3 forming main insulation is provided with between high-tension coil and low-voltage coil, this curtain oil duct is bonded on cardboard 32 by stay 31 and forms, and the side of stay is towards low-voltage coil; Outside high-tension coil, be positioned at A, C phase be respectively wound with corrugated board 4; One and half oil ducts 5 are provided with in high-tension coil inside.Corrugated board mainly plays the insulating effect between coil and fuel tank, can reduce the safe distance between coil and fuel tank thus.High-voltage coil and low-voltage coil inside arranges half oil duct of right quantity as required, the quantity of half oil duct and the temperature rise of coil suitable, the quantity of half oil duct according to the temperature rise situation of coil through Row sum-equal matrix.One and half oil ducts are evenly arranged at high-tension coil inner.The stay that half oil duct is not waited by thickness is bonded on cable paper and forms.
During coiling, stay side is to low-voltage coil, to be more conducive to heat radiation.Respectively be wound around a corrugated board in the outside of A, C phase coil after coil winding completes, corrugated board mainly plays the insulating effect between coil and fuel tank, can reduce the safe distance between coil and fuel tank thus.
Use the oval coil of this structure, the production cycle is shortened, and cost have also been obtained effective control, greatly improves the competitiveness of product in market.This oval coil is safe and reliable, has saved the energy, has saved raw material, fullys meet the production economizing type of country's proposition, the requirement of energy-saving product.
