<p>PURPOSE: To simply constitute a distribution gap for a cooling medium for cooling windings between an inner insulation cylinder and an outer insulation cylinder. CONSTITUTION: A plurality of windings wound in a disc form are used as 1 block, and a plurality of the blocks are arranged between an inner insulation cylinder 1 and an outer insulation cylinder 2. With respect to each block, inner spacers 11 having heat resistance and flexibility are pressed into each space surrounded by the inner periphery of a winding at the highest stage of a block, the inner insulation cylinder 1, and inner neighboring vertical ducts 5 as well as each space surrounded by the outer periphery of a winding at the highest stage of another block adjoining to said block, an outer insulation cylinder 2, and outer neighboring vertical ducts 6, thereby clogging the spaces. A gap between unclogged windings and insulation cylinder at the opposite side is used as a medium distributing gap.</p> |
