Abstract
A gas insulated switchgear includes a transformer mounting body; a bushing mounted on the transformer mounting body; and a main circuit conductor. The main circuit conductor includes a first main circuit conductor which is connected to a circuit breaker and is located in the bushing and a second main circuit conductor which is connected to the first main circuit conductor. An insulator extends below the lower end of the transformer mounting body and toward the vicinity of the connection between the first main circuit conductor and the second main circuit conductor, in a region where the first main circuit conductor is located in the transformer mounting body. A ground shield is arranged in the insulator, and extends below the lower end of the transformer mounting body and above a coupling portion between the transformer mounting body and the bushing.
