<p>PURPOSE: To obtain a gas insulated switchgear in which layout of machine can be facilitated while decreasing the overall installation area. CONSTITUTION: Two stages of bus conduits 21, having a coupling section 21A with a PCT unit 2 in the center, are disposed on the back side of an operating board 20 and a transformer primary unit 3 is coupled with the end of upper stage conduit whereas a bus disconnector housing section 23 is coupled with the end of lower stage conduit. The coupling section 21A is coupled with the PCT unit 2 and the bus disconnector housing section 23 is coupled with the CB housing section 1B of a power receiving unit 1. The power receiving unit 1 is constituted by coupling the lead-in section 1A and the CB housing section 1B directly. A PCT is fixed to the PCT unit 2 and a transformer 5 is coupled through a conduit 22 with the transformer primary unit 3. Operating units are housed collectively in the operating board 20.</p> |
