<p>PROBLEM TO BE SOLVED: To reduce a space required by decreasing the number of units constituting a gas-insulated switchgear(GIS) of 2L-2Tr type (with MOF bypass, section disconnector). SOLUTION: Bus circuit section units 21, 22 provided at first and second bus lines 1, 2 are constituted with one unit 23, 24 housing a disconnector and a ground switch and one unit 25, 26 housing a disconnector. An unit housing a disconnector only is arranged at the bus position of adjacent power receiving circuit unit and transformer unit 5. Since these positions were conventionally not used, the conventional three units can be substantially reduced to one is GIS layout.</p> |
