<p>PURPOSE:To facilitate matching of rotary angle between gas insulated bus bodies by providing a connecting unit with an elevating frame to be guided vertically through a driver and disposing an axial supporting roller and a peripheral supporting roller, respectively, at one and the other upper ends of the elevating frame and the connecting unit. CONSTITUTION:An elevating frame 3 is guided vertically through an elevating driver 2 with respect to a movable connecting unit 1. A pair of axial supporting rollers 4 are disposed at least one upper end of the elevating frame 3 or the connecting unit 1 and a pair of peripheral supporting rollers 5 are disposed at the other upper end. Switching is made between the upper end supporting faces of the one and the other rollers 4, 5 through vertical movement of the elevation driver 2 thus supporting a main bus body 14 on the outer periphery thereof. According to the constitution, respective elements of gas insulated main bus, installed in power plant or substation, can be connected quickly in safety.</p> |
