<p>PURPOSE:To obtain a gas insulation switchgear of high reliability by connecting two or more fixed seats, provided on a floor slab in the periphery of a common base, to the common base by an elastic unit. CONSTITUTION:A common base 4 is set up on a foundation base 2, set up on a floor slab 1, through two or more vibro-isolating rubbers 3 possible to extend/contract in a vertical direction. Fixed seats 6 are provided in corner parts in four places on the floor slab 1 in the periphery of the common base 4, and this fixed seat 6 is connected to the common base 4 by a horizontal connecting rod 7. The horizontal connecting rod 7, in an insertion part of which in a side of the fixed seat 6 a spherical washer 9 is inserted into one side opposite to a side of the common base 4, is fixed by a nut 10 and slidably placed in a vertical direction by a part of a through hole 8. The horizontal connecting rod 7, in an insertion part of which in a side of the common base 4 spherical washers are mounted to both sides of a through hole 8, is fixed by nuts 10 and slidably placed in a vertical direction by a part of a through hole 8.</p> |
