<p>PURPOSE:To provide a gas insulated switching apparatus in which an outage period of a transmission line and a switching facility of an electric station is shortened and a step-up operation can be facilitated in the case of a voltage step-up work of the line. CONSTITUTION:The gas insulated switching apparatus comprises a high-voltage aeries transmission line 1A, a high-voltage bushing 2A connected with the line 1A, a low-voltage transmission line tripping unit connected to the bushing 2A, a low-voltage gas insulated switching unit 19 connected through the tripping unit, and a step-up high-voltage gas insulated switching unit 20. At the time of removing the tripping unit, the unit 20 is connected to the bushing 2A instead of the unit 19.</p> |
