<p>PURPOSE:To forms a secondary conductor so as to be flat and thin and to increase the cooling effect of the title transformer. CONSTITUTION:A secondary conductor 10 forms a cooling water passage 15 which is passed through the inside; it is constituted to be a nearly ring-shape in which an iron-core insertion part 12 has been formed at the inner peripheral part. The secondary conductor 10 is constituted in such a way that secondary- conductor formation members provided with cooling-water passage formation grooves on one face have been bonded in a liquidtight manner. Consequently, the cooling-water passage 15 can be formed by bonding the secondary-conductor formation members. The secondary conductor 10 can be molded easily. The cooling-water passage 15 can be made long and its cross-sectional area can be made large. The title transformer can be made flat and thin, and its cooling effect can be increased.</p> |
