The Influence of Different Morphologies of the Insulation Cylinder in the Main Air Duct of Dry-type Transformers on Winding Temperature Rise and Electric Field

Through hydrodynamic simulation analysis, the influence of different morphologies of PET insulating cylinders in the main air duct of dry-type transformers on winding temperature rise was analyzed, and the influence of different morphologies on the electric field between high-voltage and low-voltage windings was also analyzed.
