Abstract
The utility model relates to the technical field of power electronics, in particular to a transformer. The wind power generation transformer with an air cooling passage comprises a transformer body which comprises an iron core and a coil wound on the iron core; a stainless steel tube and the air passage which is formed by the stainless steel tube between the coil and the iron core are also arranged between the coil and the iron core; a ventilation opening of the air passage is provided with a draught fan which is arranged outside the transformer; and an air blowing opening of the draught fan faces to the ventilation opening of the air passage. For the wind power generation transformer, the air cooling passage formed by the stainless steel tube is arranged between the coil and the iron core; and compared with the traditional structure which dissipates heat through the air passage formed by arranging cushion blocks, the wind power generation transformer provided by the utility model effectively improves the heat dissipation effect.
