<p>PROBLEM TO BE SOLVED: To provide a gas insulated switchgear with good operability. SOLUTION: This gas insulated switchgear is provided with main buses 107a to 107d, forming double lines by connecting and extending in almost a straight line constituent units, including a bus dividing unit 104 comprising gas-blast circuit breakers 108a to 108d provided in each position near the center, a bus communicating units 103a, 103b comprising gas-blast circuit breakers 108' which are provided in each position on both sides of the boundaries formed by the bus-dividing unit 104 and a detector unit, comprising voltage detectors 109a to 109d. The main buses are divided into four blocks in total with gas-blast circuit breakers 108a to 108d, constituted as double gas-blast circuit breakers connected in series structured by connecting two gas-blast circuit breakers in series, and the voltage detectors 109a to 109d are provided at each position in each of the floor blocks positioned at both sides of the series gas-blast circuit breakers.</p> |
