<p>PURPOSE:To prevent the local overheat near bushing-fitted portion by providing bushing for the outgoing line of transformer to transformer tank and also by providing bushing of reverse current polarity to the bushing to reactifier. CONSTITUTION:The partition wall between the transformer tank 1a of multi- phase transformer and the rectifier case, which are linked by a double star connection, is provided with the bushing 11 in close proximity to the bushing 6 so that they are in a pair. And, the terminal of the winding 2 is drawn out through the bushing 6 into the rectifier case 1b, and then connected to the rectifier group 7, and also through the bushing 11, the cathode side is connected in common inside the transformer tank 1a and then connected to the bushing 5p. Thus, since the current flowing in the bushings 6 and 11 becomes reverse polarity, the local overheat at the side wall of the transformer tank 1a fitted with the bushing 6 can be prevented.</p> |
