<p>PURPOSE:To provide a gas insulated switchgear with reduced overall size and installation area while enhancing the safety. CONSTITUTION:A gas insulated switchgear equipped with a plurality of switches is connected with a main bus and then connected through bushings 10a, 10b, 10c with an overhead transmission line. The switches are arranged on a substantially linear three-phase one-enclosure type line. The bushings 10a, 10b, 10c are arranged on a single phase line extending in parallel with the three-phase one-enclosure type line. The bushings 10a, 10b, 10c are disposed such that the lower end parts thereof are set above the uppermost part of the switches arranged on the transmission line. The operating box for the switches is disposed oppositely to the lowermost part of the bushing 10a, 10b, 10c in the transmission circuit.</p> |
