電器機器容器の接続装置を提供するにある。The object of the present invention is, even in the case of connecting between electrical equipment containers, the local stress due to thermal expansion does not become excessive, and the manufacturing error absorption adjustment work can be easily performed even at the time of on-site installation, of course. An object of the present invention is to provide a connection device for an electrical equipment container that does not reduce the reliability of the seal portion and that can reduce the installation space.
本発明では上記目的を達成するために、電気機器容器

がなくなる。With the configuration of the present invention described above, even if thermal expansion of an electric equipment container such as a gas insulated switchgear occurs, it is absorbed by the flexibility of the corrugated bellows formed in a part of the container,
For example, there is no excessive local stress at the mounting portion between the transformer tank and the pocket. Similarly, the flexibility of the corrugated bellows facilitates the work of mounting the connection between the transformer tank pocket and the gas-insulated switchgear sheath, and eliminates leakage from the sealing surface.
以下、本発明の一実施例として油入変圧器とガス絶縁
開閉装置の例を第１図により説明する。Hereinafter, an example of an oil-filled transformer and a gas-insulated switchgear will be described with reference to FIG. 1 as one embodiment of the present invention.

済性の向上，据付スペースの低減といつた効果がある。On the side surface of the transformer tank 1 containing the insulating oil 11 and the contents in which the iron core 10 and the winding 6 wound therewith are integrated, a single bellows 9a and a pocket 2a provided almost in the middle are provided.
The end of the pocket 2a is a flange, and a partition wall 4 is mounted to partition the SF 6 gas 12 and the insulating oil 11. The periphery of the partition wall 4 is made a business trip from the pocket 2a to form a flange, and a connection bolt hole is made. Further, a mounting seat is provided on the partition wall 4, and a bushing in oil-gas (wall bushing) 3 is provided.
Install. A lead wire 7 drawn from the winding 6 is connected to the oil-side side of the oil-in-gas bushing 3, and a gas-insulated switchgear conductor 8 is connected to the gas side. Furthermore, the partition wall 4 and the gas-insulated switchgear sheath 5 are connected to form a direct connection between the oil-filled transformer and the gas-insulated switchgear. According to this embodiment, a separate bellows is not required, and the sealing surface of the connection between the transformer and the gas insulated switchgear is reduced, so that the reliability against oil leakage is improved. Further, there are effects such as reduction in the number of assembling steps, improvement in economic efficiency, and reduction in installation space.
