<p>PURPOSE:To decrease the number of components by providing an enclosure for housing in interrupter unit with a plurality of connection ports thereby eliminating the need of a dedicated connection port. CONSTITUTION:An enclosure 1 for housing an interrupter unit of a composite gas insulated switchgear having single bus structure is connected, at a connection port 2 thereof, with the interrupter of main bus through a main bus disconnector 4. Furthermore, a moving cable 6 is connected through a cable adaptor 5 with a connection port 3 disposed below the connection port 2. The connection port 2 is connected, on the front thereof, with a cable head 19 provided on a frame 20 incorporating a CT for passing thecable. This structure decreases the number of components and reduces the manufacturing cost. The main bus interrupter serves as a protector against the faults occurring frequently on the side closer to the main bus than the disconnector 4 and the moving cable is used continuously for receiving and transmitting power.</p> |
