Support Structure For At Least One Winding Of A Power Transformer, Power Transformer And Method For Manufacturing

Abstract: The present disclosure relates to a support structure (10) for at least one winding (24) of an inductive device, in particular a power transformer (20), comprising a press structure (11) configured to transfer and distribute an compression force from a holding structure to the at least one winding (24), an insulator structure (12) configured to electrically insulate the holding structure from the at least one winding (24), and a coolant flow structure (13) configured to guide and distribute a flow of a liquid coolant to or from different parts of the at least one winding (24). The press structure (11), the insulator structure (12) and the coolant flow structure (13) are formed as one integrated part comprising a polymer material. The integrated part comprises a plurality of orifices (14, 15) for passage of the liquid coolant from a first side (16) facing the holding structure to a second side (17) facing the at least one winding (24). The present disclosure further relates to a power transformer (20) comprising such a support structure (10) and a method for manufacturing a support structure (10).
