<p>PURPOSE:To reduce the wiring and installing space occupied by the whole of a gas insulated switchgear having a large-scale disconnecting switch on the bus side belonging to a phase separation type circuit breaker and a disconnecting switch on the line side. CONSTITUTION:A bus conductor 1 is connected directly to a contact portion 5 at the fixed side of a disconnecting switch 3 and a contact portion 5 at the fixed side is retained by the first insulation spacer 4 provided at the side face of a sealed container 30. The leading direction of a bus connecting conductor 2 supported by the first insulation spacer 4 is located perpendicular to the leading direction of a circuit breaker connecting conductor 13 supported by the second insulation spacer 8 and electrically connected to a contact portion 6 on the moving side. By so doing, the disconnecting switch 3 on the bus side belonging to a phase separation type circuit breaker and a bus on the line side and a main bus connected to a disconnecting switch on the line side are located at lower positions, by which the wiring and installation space occupied by the whole of a gas-insulated switchgear can be reduced.</p> |
