<p>PROBLEM TO BE SOLVED: To provide a gas-insulated apparatus which enables practical reduction of necessary quantity of SF6 gas in it without increasing its size and elevating a gas pressure as will as, can obtain sufficient insulation performance. SOLUTION: Mixed gas 40, consisting of the mixture of two or more types of gases including SF6 gas, is sealed in a metal container 2. Further, a high voltage conductor 1 for current application, and an insulator 3 which supports the high voltage conductor 1 and insulates it from the metal container 2, are provided in the metal container 2. An SF6 gas adsorbing part 5 which adsorbs SF6 gas is provided on at least one place among the surface of the high voltage conductor 1, the surface of the metal container 2 and the surface of the insulator 3.</p> |
