Abstract

PURPOSE:To prevent increase of iron loss in a split-type autotransformer by a method wherein the transition of high-voltage lead wires of one autotransformer are built in one iron core outer leg part of another autotransformer and crossover tracks of a neutral-point lead and a midium-voltage lead are built in the other iron core leg part. CONSTITUTION:Windings 8C and 8D are wound on the main leg part of the shell type cores 14C and 14D of two autotransformers C and D, respectively. The transition 15 of high-voltage lead 11C of one autotransformer C is connected with a high-voltage bushing 18 along with lead 11D of the same kind of another autotransformer D via the side facing one iron core outer leg 14D1 of the autotransformer D. Crossover tracks 16 and 17 of a medium-voltage lead 12C and a neutral-point lead 13C are connected with a medium-voltage bushing 19 and a neutral-point bushing along with leads 12D and 13D of the same kind of transformer D, respectively, via the side facing the other iron core outer leg part 14D2 of transformer D. With this construction, split autotransformers can be connected in parallel with increase of neither the size of a transformer tank and an installation area nor the iron loss.
