<p><P>PROBLEM TO BE SOLVED: To obtain an enclosed type switchgear in which the cost can be reduced by decreasing the number of components while enhancing the insulation performance. <P>SOLUTION: The enclosed type switchgear comprises a disconnector 5 and a vacuum valve 3 for each phase juxtaposed to each other, an enclosed container 1 containing the disconnector 5 and the vacuum valve 3 and encapsulated with insulating gas, and insulating tubular container 2 having a substantially tubular body 2a made of an insulating material and standing on a specified supporting surface 1a in the enclosed container 1 while containing the vacuum valve 3 in the body 2a and supporting the disconnector 5 at the outside part of the body 2a, and an intermediate conductor 4 provided at the opening end part 2c on the side of the body 2a of the insulating tubular container 2 opposite to the supporting surface 1a and securing the vacuum valve 3 in the insulating tubular container 2 while being connected electrically with the first terminal conductor 3a thereof wherein the insulating tubular container 2 has a first insulating barrier part 2d formed integrally with the body 2a and standing at the opening end part 2c to surround the intermediate conductor 4 at least partially. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
