<p>PROBLEM TO BE SOLVED: To obtain a gas-insulated switchgear which realizes miniaturization, reduction in installation area and improvement in installation work, maintenance and inspection services. SOLUTION: This gas insulated switchgear is provided with at least double main buses 100A to 200B, having bus sectionalizing switching device units 7, 8, transmission lines L11 to L32 comprising a plurality of circuits, and transmission line switch device units 3 to 14, each connected between the double main buses connected to the one of the circuits and the one end of the bus sectionalizing switching device units and to the other end of the circuits and the other end of the bus sectionalizing switching device units and then provided with gas-blast circuit breakers 1A to 15C structured vertically. In this case, the transmission lines are arranged in many directions against the double main buses, and gas-blast circuit breakers 1A to 15C are each arranged along the one side part of the double main buses.</p> |
