Abstract

PURPOSE:To mount a monitor camera for fixing, and to automate a gas insulation switching device while reducing the space of installation without forming a dead space by inclining the axis of a bus conduit line to the direction of connection of a unit at an angle other than right angles. CONSTITUTION:The operating devices 15 of each circuit unit 1a-4a can be monitored from a point A on the inspection path 16 side. It is because an axis (a) for connecting mutual bus conduit lines 5 and an axis (b) for connecting each unit are inclined without at a right angle. Consequently, when a monitor camera 18 is mounted at the point A, an unmanned gas insulation switchgear can be acquired. Since the positions of the operating devices 15 are separated from the mutual bonding sections of the bus conduit lines 5, the mutual bonding work of each circuit unit differs from conventional devices, and is facilitated. Each inspection window of the operating devices in all circuit units 1a-4a can also be inspected from the point A on the path 16 side, thus scaling down the mutual clearances of the circuit units, then miniaturizing the gas insulation switchgear.

Each inspection window 17 of the operating device in ~4a can also be inspected from point A on the passage 16 side. Conventionally, adjacent circuit units overlapped in the area corresponding to the inspection window 17, which required a space large enough for an inspector to enter and inspect, and for this reason, the gap between the circuit units had to be made large. However, in the present invention, there is no such need, so the gap can be made smaller by that amount, and the gas insulated switchgear can be made smaller.
