Abstract

PURPOSE:To realize compact and light weight of the device by a method wherein a low-voltage winding, a medium-voltage at neutral point side, and a high-voltage winding are successively applied to an iron core from the inside for accommodating them in a tank and a low-voltage winding, a high-voltage winding at neutral point side, and a medium-voltage winding are successively applied to an iron core from the inside for acccommodating them in the other tank and a tap winding is provided at one iron core. CONSTITUTION:A low-voltage winding 31, a medium-voltage winding 21 at neutral point terminal side, and a high-voltage winding 11 are applied to an iron core 51 from the inside for accommodating them in a tank 61, and a tap winding 4, a low-voltage winding 32, a high-voltage winding 21 at neutral point side, and a neutral-voltage line winding 22 are applied to an iron core 52 from the inside for accommodating them in a tank 62. The windings, 11 and 12, 21 and 22 are connected in series and the windings 31 and 32 in parallel through oil ducts. When high and medium-voltage windings are of stepped insulation and while the medium-voltage winding 21 has electric potential higher than the high-voltage and neutral point winding 12, the distance between the iron core leg and the tank wall becomes l3>l4 in an example of an actual equipment. However, in this composition, l3 can be shortened by as high as 15% compared with a conventional simple two-split composition and it is very profitable for transportation.
