次に記載する効果を奏する。
Since the present invention is configured as described above,
The following effects are obtained.

主回路機器及び関連機器を収納する密閉容器を2個の
ほぼ半円筒状の容器により構成すると共に、これを並設
してそれぞれの胴板間を管路で接続するようにしたの
で、1個のほぼ半円筒状の大形密閉容器内に主回路機器
及び関連機器を収納する場合に比し、その奥行寸法を小
さくでき、据付スペースの縮小化が図れるものであり、
しかも、2個の容器の全体積が1個の大形密閉容器より
大幅に縮小化されるため、絶縁性ガスの封入ガス量も少
なくなり、安価になる。
The hermetic container that houses the main circuit device and related devices is composed of two substantially semi-cylindrical containers, and these are juxtaposed so that the respective body plates are connected by pipes. Compared to storing the main circuit equipment and related equipment in a large semi-cylindrical large hermetic container, the depth dimension can be reduced and the installation space can be reduced,
In addition, since the total volume of the two containers is significantly reduced compared to that of a single large hermetic container, the amount of gas filled with the insulating gas is reduced and the cost is reduced.

更に、小形の2個の容器で密閉容器を構成するため、
容器の胴板等の原材料寸法が小さくなり、これら材料の
入手が容易になり、かつ安価になる。
Furthermore, in order to constitute a closed container with two small containers,
The size of the raw materials such as the body plate of the container is reduced, so that these materials are easily available and inexpensive.
