Title:
GAS-INSULATED SWITCHGEAR
Document Type and Number:
Japanese Patent JP2014099381
Kind Code:
A
Abstract:

To provide a gas-insulated switchgear which can be made downsized by decreasing hight thereof.

An electric power receiving cable 5 lead from a cable 6 is electrically connected to an electric power receiving side disconnector 2a, an electric power receiving side grounding switch 2b, and an arrester 2c. A breaker 1a, in an electric power receiving side region, is connected to the electric power receiving cable 5 through the electric power receiving side disconnector 2a and is connected to a disconnector with grounding switch arranged on a downside through an insulation spacer 100c. The disconnector with grounding switch arranged on the downside includes a grounding electrode on a backside of a gas-insulated container 100a and a bus bar side electrode 3c closer to a grounding electrode 3b side rather than to an electrically connected part with the disconnector 1a. The bus bar side electrode 3c is connected to one bus bar 7a through a main circuit side electrode 4i of a disconnector with a grounding switch arranged on an upper side. The disconnector with the grounding switch arrange on the upper side includes a grounding electrode 4b in a front side of the gas-insulated container 100a. The other bus bar 7b is connected between the main circuit electrode 4i and the grounding electrode 4b of the disconnector with the grounding switch arranged on the upper side.
