PROBLEM TO BE SOLVED: To allow for early recovery of the whole transmission and transformation apparatus after occurrence of an outage, by not only preventing up-sizing but also preventing leakage of oil from a connection device even upon occurrence of an outage, thereby reducing the risk of fire, or the like, and preventing expansion of damage to an adjacent gas-insulated switchgear and/or a stationary induction electric apparatus.SOLUTION: In a connection device of a gas-insulated switchgear and a stationary induction electric apparatus, a gas-insulated switchgear side connection container and a stationary induction electric apparatus side connection container are joined while partitioned by a spacer in connection container, and when the internal pressure of any one of the gas-insulated switchgear side connection container or the stationary induction electric apparatus side connection container increases over a predetermined value, a spacer in connection container is fixed so as to deviate from the gas-insulated switchgear side connection container or the stationary induction electric apparatus side connection container, the internal pressure of which increases over a predetermined value. |
