Abstract
PURPOSE:To facilitate change-over of voltage of a transformer by a method wherein the primary side or the secondary side of the transformer having two rated voltage is constituted of an autotransformer winding of the first winding to be applied with the low rated voltage and the second winding to be applied with the high rated voltage. CONSTITUTION:The low-voltage side of the transformer is constituted of the low- voltage winding 9, while the high-voltage side is constituted of the autotransformer winding consisted of two windings of a middle-voltage winding 10 and the high-voltage winding 11. Those sindings 9-11 and a core 12 are accomodated in an oil tank 13. Both terminals 9A, 9B of the low-voltage winding 9 are led out outside of the tank 13 through air-oil bushings. A neutral point terminal 10 from one side end part of the middle-voltage winding 10, a common middle-voltage terminal 14 from the connecting part between the other end part thereof and the short-circuited both end parts of the high-voltage winding 11, and a high-voltage terminal 11A from the center of the high-voltage winding 11, are respectively led out through air-oil bushings to the outside of the tank 13. When the low-voltage is to be used, an arrester 16 is connected to the high-voltage terminal 11A.
