<p><P>PROBLEM TO BE SOLVED: To provide a small SF<SB>6</SB>alternative gas insulated instrument with insulation reliability even if alternative gas whose insulation property is inferior to SF<SB>6</SB>gas, and to secure commonality of components and ease of alternative work by making a basic structure of a gas insulated instrument itself is made similar to a conventional instrument. <P>SOLUTION: The instrument is provided with a high voltage conductor 2, a ground tank 1 for sealing the high voltage conductor 2, and an insulating supporting object 3 for insulating and supporting a part between the high voltage conductor and the ground tank. Insulating gas 5 is enclosed between the high voltage conductor 2 and the ground tank 1. The high voltage conductor 1 is constituted of an insulated cylinder 6 where a conductive material 7 is arranged on an inner face. An embedded electrode 4 arranged in a center of the insulating supporting object 3 is inserted into an end part of the insulated cylinder 6. The embedded electrode 4 and a conductive material 7 on an inner face of the insulated cylinder are electrically connected. A metallic conductor 8 is inserted into an inner side of the insulated cylinder 6, and an end part of the metallic conductor 8 is electrically and structurally connected to the embedded electrode 4 of the insulating supporting object. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
