<p>PURPOSE: To provide a gas insulated switchgear capable of changing the structure by vertical transposition, of the whole of or a part a hermetically sealed container having a built-in vacuum circuit breaker. CONSTITUTION: A gas insulated switchgear 1 uses a vacuum circuit breaker 2 and a hermetically sealed container 3, compared to a former example. The vacuum circuit breaker 2 has a hermetic flange 21 having a plurality of through holes formed fitting the center of the pitch interval dimension 2C of centers to the center of the pitch interval dimension 2B of respective centers of the contacts 83, 84. And individual through holes are formed at positions being surface-symmetrical, concerning a plane containing a center line 2A connecting the center of the pitch interval dimension 2B and the center of the pitch interval dimension 2C. The hermetically sealed container 3 has threaded holes having bottoms formed fitting the center of the pitch interval dimension 3C to the center of the pitch interval dimension 3B of respective centers of stationary-side members 73, 74, around through holes 31 at positions being opposed to individual through holes that the hermetic flange 21 has.</p> |
