The purpose of this utility model is to provide a kind of large-scale dry-type transformer iron heat radiation air flue, the defect of above-mentioned existence can be overcome, iron-core air-path space availability ratio can be made to bring up to more than 95%, thus effectively improve the result of ventilating heat dissipation of large-scale dry-type transformer iron.
Technical solution of the present utility model: a kind of large-scale dry-type transformer iron heat radiation air flue, is characterized in that the main of the upper yoke of transformer core, core limb, lower yoke or secondary main are provided with ventilation and heat air flue.
In the middle of the main of the upper yoke of described transformer core, core limb, lower yoke, a ventilation and heat air flue is set.
In the middle of two mains of the upper yoke of described transformer core, core limb, lower yoke, a ventilation and heat air flue is set respectively.
Described ventilation and heat air flue is the rectangular steel pipe of hollow, that wall is thin stainless steel.
The rectangular steel pipe one side of described stainless steel is bonded on lamination.
Described ventilation and heat air flue is disconnect on three core limbs.
Described ventilation and heat air flue is in upper yoke unshakable in one's determination, three core limbs, the upper and lower vertical out-fall of lower yoke, and the air flue set by Double layer iron yoke of three core limbs and correspondence is alignment.
Advantage of the present utility model: according to the size of transformer capacity or the height of temperature rise unshakable in one's determination, a heat radiation air flue or two heat radiation air flues are set in iron core, iron-core air-path space availability ratio brings up to more than 95%, effectively improve the result of ventilating heat dissipation of large-scale dry-type transformer iron, avoid inner local overheating unshakable in one's determination.
