タンクに伝達するように構成する必要がある。Therefore, in order to support the dish-shaped lower tank 4, which supports the 230 weight of the contents of the transformer, to the transportation tank of the upper tank that is connected to the freight car, a stay is raised from the bottom of the lower tank 4 to the upper and lower tank joining flanges. It is necessary to connect it to the tank side or provide a separate auxiliary beam to transmit the weight of the dish-shaped lower tank to the upper tank.
しかし、このような構造にすると、これらのステーやビ
ームの幅の分だけタンク内壁間の幅が狭くなり変圧器中
身の幅が制約される。However, with such a structure, the width between the inner walls of the tank becomes narrower by the width of these stays and beams, and the width of the transformer contents is restricted.
このように幅が制約されることは、今後、実用化される
超超高圧変圧器、特に１０００ｋｖ級変圧器においては
、著しい輸送上の制約となる。Such width restrictions pose a significant transportation constraint for ultra-high voltage transformers, especially 1000 kV class transformers, which will be put into practical use in the future.
従って、このような幅の制約はできるだけ少ないことが
望ましい。Therefore, it is desirable that such width restrictions be as small as possible.
