PROBLEM TO BE SOLVED: To reduce possibility of breakdown due to a rapid increase in internal pressure inside a container.SOLUTION: A connection apparatus includes: a metal connection container 20 filled with an insulating oil 21 therein; a connection conductor positioned in the insulating oil within the connection container, for electrically connecting a transformer 1 with an opening/closing device 2; a first insulating spacer 30 supporting the connection conductor and partitioning between a tank 10 of the transformer 1 and the connection container so as to prevent an insulating oil 11 within the transformer 1 from being mixed with the insulating oil in the connection container; a second insulating spacer 31 supporting the connection conductor and partitioning between a tank 12 of the opening/closing device 2 and the connection container 20 so as to prevent an insulating gas 13 within the opening/closing device 2 from being mixed with the insulating oil in the connection container; pressure discharge containers 90a and 90b filled with a gas therein and connected to the connection container; and bursting plates 91a and 91b partitioning between the pressure discharge containers and the connection container so as to prevent a gas within the pressure discharge containers from being mixed with the insulating oil within the connection container, and when receiving pressure of a predetermined value or more, being broken to release the partition. |
