Title:
DC GAS-INSULATED SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2018/142449
Kind Code:
A1
Abstract:
Provided is a DC gas-insulated switchgear that does not require work for opening a tank to extract an insulating gas and closing the tank to fill the tank with the insulating gas when a new power supply circuit is added to a power supply circuit and can save time and cost required for the work. The DC gas-insulated switchgear 1 is internally provided with a high potential side power supply line 2 for supplying a DC power, a ground potential side power supply line 3, and a switch portion 8 for switching the high potential side power supply line 2, and has tanks 9, 9a, 9b filled with the insulating gas. A part of the ground potential side power supply line 3 is relay-connected by a relay portion having at least a first air bushing 14a and a second air bushing 14b that are disposed in the air outside the tanks and having an overhead line 15 connected between the first air bushing 14a and the second air bushing 14b.
