METHOD OF FORMING A DISC-WOUND TRANSFORMER WITH IMPROVED COOLING AND IMPULSE VOLTAGE DISTRIBUTION

摘要

A method of manufacturing a transformer is provided. The method includes forming a disc-wound coil by forming a first conductor layer, a second conductor layer and a layer of cooling ducts between the first and second conductor layers. The first and second conductor layers each have a plurality of disc windings arranged in an axial direction of the disc-wound coil. Each of the disc windings includes a conductor wound into a plurality of concentric turns.
