<P>PROBLEM TO BE SOLVED: To provide a gas insulated switchgear which effectively utilizes the space within a vessel for smaller switchgear, reduced number of components, and compactness as a whole. <P>SOLUTION: An insulating gas is sealed in a vessel which is grounded and houses a bus bar conductor. It is provided with two fixed side collectors in the same direction with the bus bar conductor, a contact member so arranged as to face them, and a movable contact conductor which is slidably inserted in the contact member and opens/closes between the fixed side collector and the contact member, providing a ground switch with one end of a disconnection part while the fixed side collector of the other end being grounded. Thus, a three-position type disconnection/ground switch is provided. <P>COPYRIGHT: (C)2004,JPO
【課題】容器内のスペースを有効に利用して、開閉器の縮小化及び構成部品数の低減化を図り、さらに装置全体のコンパクト化を図ったガス絶縁開閉装置を提供することにある。 【解決手段】本発明では絶縁性ガスが封入され、接地された容器内に母線導体を収納すると共に、母線導体と同一方向に2つの固定側集電子とこれに対向するよう配置された接触部材及びこの接触部材内に摺動自在に挿入されて固定側集電子と接触部材間を開閉する可動接触導体を設けて、片端は断路部で、もう片端の固定側集電子は接地して接地開閉器とすることで三位置形断路・接地開閉器を構成することを特徴とする。 【選択図】 図2
