<p><P>PROBLEM TO BE SOLVED: To provide a gas insulated switchgear obtaining down sizing and simplification in an interior structure of a disconnector/grounding switchgear and the gas insulated switchgear apparatus as a whole as well as contributing to reliability and economical efficiency, by improving the interior installment structure of the disconnector/grounding swicthgear, and obtaining at the same time a contact structure of linear motion three-position type, a serial installment of driving shafts and in addition a slanted way installment of the disconnector making possible practical installment of equipments. <P>SOLUTION: A connecting conductor 18 connecting to an insulating spacer 11 is provided to be in parallel with a sliding shaft 21 of a movable contact 7 in a branch bus-bar 107 provided adjacent to a bus-bar side disconnector/grounding switchgear 140. Furthermore, a shaft 16 of a supporting conductor 10 of a moving contact 6 is installed to form an angleαwhich is 0<α≤90°for a sliding shaft 21 of the moving contact 7. The sliding shaft 21 of the moving contact 7 is provided almost as a right angle to an axis 5 of a bus-bar conductor 3. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
