GAS-INSULATED SWITCHGEAR

PURPOSE:To make easy the maintenance and check of line disconnecting device and operating device of grounding apparatus without allowing increase of an installation area. CONSTITUTION:One of the gas insulated switchgears of adjacent phases between a couple of lines comprises an upper container 9a and a lower container on the axial line shifted onto the opposite side rather than the center line in parallel with the phase direction of the cut-off container 6a of such phase, while the other of the gas insulated switchgear comprises an upper container 9d and a lower container on the axial line shifted into the opposite side rather than the center line in parallel with the phase direction of the cut-off container 6d of the phase direction. A disconnecting device and operating devices 23 to 25 of the grounding apparatus are provided in the opposing area of both gas insulated switch devices.
