[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are coils and iron cores. Dry-type transformer is a type of power transformer. When the dry-type transformer is powered on, the magnetic flux passing through the iron core will cause losses in the iron core, and the current passing through the winding will also cause losses in the winding. In addition, the leakage flux caused by the winding current and the leakage flux outside the iron core when the iron core is overexcited will cause additional losses in various structural parts, such as windings, iron core structural parts, iron core sheets and other metal structures. Various losses are converted into heat. Part of this heat is used to increase the temperature of each component, and the other part is used to dissipate heat to the cooling medium attached to each component. During the operation of the dry-type transformer, air is circulated naturally (when the load is low, fans are generally not used) or air is forced to circulate (when the load is high, fans are generally used).
