PURPOSE:To make the flow rate and distribution of cooling oil for a horizontal oil path uniform by previously mounting an oil flow controlling member to one of oil flow guide plates disposed among winding groups when a large number of discoid winding are stacked outside of an inside insulating cylinder in the height direction at regular intervals and the horizontal oil path is formed among these winding. CONSTITUTION:A large number of discoid winding 1 are stacked outside the inside insulating cylinder 4 in the height direction at regular intervals, and an inside vertical oil path 4 is formed among an outer surface of the insulating cylinder 1 and the periphery of the winding 1 through a vertical spacer 10. The horizontal oil paths 3 are formed among the winding 1 through horizontal spacers 9, and the first oil flow guide plate 7 contacting with the insulating cylinder 1 is made up for every group of the groups of these coils 1 and the second oil flow guide plates 8 with clearances among the insulating cylinder 1, facing to the plate 7. A laminar oil flow controlling member 11 covering the edge sections of the upper and lower winding is mounted previously to an end section of the guide plate 7 in this constitution, and the amount of cooling oil flowing in the horizontal oil paths 3 of the upper and lower winding sections is decreased. |
