Abstract
The invention discloses a 40.5 KV outdoor Gas Insulated Switchgear (GIS) which comprises a gas case, a spring operation mechanism, a vacuum circuit breaker, an inlet wire side fixed contact of an isolation grounding three-position switch connecting with an inlet cable, and an outlet wire side fixed contact of the isolation grounding three-position switch connecting with an outlet cable of the isolation grounding three-position switch. The inlet wire side fixed contact of the isolation grounding three-position switch and the an outlet wire side fixed contact of the isolation grounding three-position switch are connected with left and right ends of an insulation screw rod, and thread directions of the two ends of the insulation screw rod are opposite. The insulation screw rod connects with a screw rod drive mechanism. Left and right moving contacts of the isolation grounding three-position switch is engaged with the insulation screw rod through internal screw thread. A grounding fixed contact connecting with the insulation screw rod is provided between the left and right moving contacts of the isolation grounding three-position switch. The vacuum circuit breaker is provided in the gas case. The 40.5 KV outdoor Gas Insulated Switchgear (GIS) has the advantages of reasonable structure, convenient examination and repair, and good product performance.
