Zusammenfassung: | To provide an oil-filled transformer having a tank support structure capable of suppressing vibration of a tank.SOLUTION: In an oil-filled transformer that includes an iron core-coil assembly in which an iron core and a coil are assembled in a tank 10 and stores insulating oil, the tank 10 includes a body portion 13 composed of a bottom plate 12 and a side plate, and the side plate protrudes below the bottom plate 12 and has a base 14 for supporting the tank 10. The base 14 has a bottom plate support portion that supports a bottom plate 12 having a height different from that of a side plate support portion that supports a side plate protruding below the bottom plate 12. The bottom plate 12 is fixed by welding on the side of the side plate and the base 14 side of the bottom plate 12 inside the body portion 13 and the side plate protruding below the bottom plate 12 is fixed to the base 14 by welding at the side plate support portion. The base 14 is configured to be fixed to the bottom plate 12 by welding at the bottom plate supporting portion.SELECTED DRAWING: Figure 1
【課題】タンクの振動を抑制可能なタンク支持構造を有する油入変圧器を提供する。【解決手段】鉄心とコイルとを組み立てた鉄心−コイル組立体をタンク10内に収納し、絶縁油を入れてなる油入変圧器であって、タンク10は、底板12と、側板からなる胴体部13で構成され、側板が底板12よりも下に突き出ており、タンク10を支持するベース14を有する。べース14は、底板12よりも下に突き出た側板を支持する側板支持部と異なる高さの底板12を支持する底板支持部とを有する。底板12は、胴体部13の内側で側板と底板12のベース14側で溶接により固定され、底板12よりも下に突き出た側板は側板支持部で溶接によりベース14に固定される。ベース14は、底板支持部で底板12と溶接により固定されるように構成する。【選択図】図1 |
