Abstract

PURPOSE:To reduce the volume of the maximum transport unit of a 3-phase transformer to 1/4 of the integral transformer by composing the trnsformer with on-load voltage regulator of three unit single-phase transformers and one unit 3-phase transformer with one on-load voltage regulator, and electrically connecting them via oil ducts. CONSTITUTION:3 unit single-phase transformers 21-23 are composed respectively of line side high voltage windings 27, low voltage windings 28 and a tank 29 for containing these windings. One unit 3-phase transformer 20 separate from these transformers is composed of neutral point side high voltage winding 30 and low voltage winding 31 of respective phases wound on a 3-phase core, and a tank 32 for containing them. Further, an on-load voltage regulator 4 separate similarly from them is composed of a 3-phase core, high voltage tap winding 10 and low voltage winding 11 of respective phases wound on the core, an on-load tap changer, and a tank 13 for containing them. Thus, these components are formed divisibly, and are electrically connected via oil ducts 5, 6. In this manner, these components can be individually transported, and can be readily assembled in a field, e.g., a remote and secluded location.
