PURPOSE:To prevent the deterioration of a winding by elevationally displacing a coil high temperature part between adjacent oil passage blocks with oil flow control member mounted, thereby preventing the local temperature rise and uniformalizing the temperature rise over the entire winding. CONSTITUTION:An oil flow control member 8 is projected on the outer periphery of an insulating cylinder 3 between vertical oil passage spacers 6 and 6 on the lower position from the intermediate between the upper and lower folding flow plates 5 and 5 of a folding zone 11 at a block (b). Accordingly, in the block (b) the oil flow from the outer periphery of a winding 11 to the inner peripheral side between coils 1 is limited by an oil flow control member 8 at the flow velocity at the vertical oil passage 4. The oil passage block formed circumferentially is disposed alternately between the blocks (a) and (b). |
