<p>PURPOSE:To provide a gas-insulated switchgear which requires a small installation space, enables two lines to be led out, is less in protruding amounts of gas-insulated main buses and circuit breaker from a dead-end tower, and can properly arrange the positions of bushings for leading out lines. CONSTITUTION:Two parallel gas-insulated main buses 6 are arranged perpendicularly to air-insulated main buses A and B. Circuit breakers 2 for bus are respectively provided above the buses 6 and the circuit breakers 2 corresponding to each bus 6 are connected to each other with an L-shaped connection bus 10 having one side perpendicular to the buses 6. Two gas-insulated circuit breakers 3 are arranged in parallel with the buses 6 and connected to one side of the bus 10 parallel to the buses 6. Lines (a) and (b) are led out from the side of the circuit breaker 3 opposite to the bus 10 in the axial direction of the circuit breakers 3.</p> |
