Abstract
PURPOSE:To simplify an industrial process for retaining air-tightness and facilitate manufacture, by connecting a mechanism case common to all of disconnectors and earthing switches, to a bottom plate. CONSTITUTION:In a cubicle-formed vessel 102 supported on an operator box 101, a lightening arrester LA, a breaker CB, disconnectors DS1-DS3, and earthing switches ES1-ES4 are contained, and at a section on one end side of a ceiling board, a bushing B is fitted. At the bottom plate of the cubicle vessel 102, a rectangular opening section is set, and at its peripheral edge, the upper end opening section of a box type mechanism case 130 is welded air-tight and is integrated with the vessel 102. As a result, an industrial process for providing the cubicle vessel with the surface of retaining air-tightness is not needed, and manufacture is facilitated.
