PURPOSE:To enable securing the sufficient space for protection devices such as a cooler or a lightning guard, improving the efficiency of cooling and miniaturizing a total equipment by taking out the high voltage lead wires for two phases or mor from a single wire through the same spacer and the same duct from a tank which contains a transformer. CONSTITUTION:Lead wires 5a, 5c for three phases are taken out from a tank 1 which contains a transformer consisting of an iron core 2 and windings 3a, 3c through a three-phase spacer 8 and a duct 9. This reduce the area of the wall of the tank 1 required for penetration compared with the case of taking out each for one phase, contrives to miniaturize the total equipment, also makes the installation of the piping for cooling easy and contrives the improvement of cooling efficiency. |
