<p>PURPOSE:To reduce the installation space by a method wherein, when leading out leads from a single phase transformer constituted of a plurality of side-placed unit transformers, high and medium pressure lead ducts wherethrough leads are passed are provided by positioning a high pressure lead duct on the lower side at one side of the longitudinal side surface of a tank, and high and medium pressure bushings are arranged at right angle to the longitudinal direction of the tank. CONSTITUTION:The single phase transformer is constituted of unit transformers 5A and 5B, a winding 25 constituted of a high pressure series winding, a medium pressure shunt winding and a low pressure tertiary winding of the transformers 5A and 5B are wound around the main leg of an iron core in the tank 23. Thereat, the transformers 5A and 5B are side-placed in parallel by opposing the side surface in the longitudinal direction to each other, and the periphery is surrounded by a sound-proof wall 4. Next, the high pressure lead 14 and the medium pressure lead 15 led out therefrom are passed respectively through high and medium pressure lead ducts 30 and 31, of these ducts, the numeral 30 is positioned on the lower side, and the numeral 31 is positioned on the upper side, accordingly arranged in the longitudinal direction of the tank 23. Further, high pressure and medium pressure bushings 16 and 17 are arranged by being projected out of the tank 23.</p> |
