WINDING STRUCTURE FOR INDUCTION ELECTROMAGNETIC DEVICE

摘要

PURPOSE:To uniformly cool a winding to be used in an induction electromagnetic device and reduce the max. point temp. in the winding. CONSTITUTION:Many sections 1A-1E stacked in multiple stages between an inner and outer insulation tubes 2 and 3 are partitioned into groups of plural sections. Flow gaps 10 and 10A are formed between the insides of the lowermost sections and inner insulation tube 2 and between the outsides of the lowermost sections and outer insulation tube 3 alternately at the adjacent groups. Deflecting members 11 and 11A are disposed near the flow gaps 10 and 10A so that a coolant passing through the flow gaps 10 and 10A may flow gradiently to the partitioned sections. Spacers 12 and 12A to block the coolant from flowing are formed each between the opposite side face of each lowermost section to the side face which forms the flow gap 10 and inner or outer insulation tube 3.
