ていることを特徴とするガス絶縁開閉装置。[Claims for Utility Model Registration] Components of a switching circuit are housed in an outer shell, two-phase bushings at both ends are equipped with a pair of voltage and current input terminals, and a middle-phase bushing is equipped with one voltage input terminal. A power supply and demand instrument transformer is installed in a triangular arrangement on the upper part of the transformer container housing the transformer body. In a gas insulated switchgear connected to a conductor, the outer shell container includes first and second containers arranged at positions apart from each other with their axes directed in the vertical direction;
a third container disposed between the first and second containers with its axis directed in the lateral direction, one end connected to the top of the first container and the other end connected to the top of the second container; The first to third containers are filled with an insulating gas, and the three-phase bus conductor connecting the electric power supply and demand instrument transformer is placed in the third container. The power supply and demand instrument transformers are arranged parallel to each other along the axis of the third container, and the power supply and demand instrument transformers
The phase bushings are placed in the corresponding two in the third container.
The transformer container is arranged in a space below the third container in a state where the transformer container is tilted with respect to the longitudinal direction of the bus conductor so as to be located between the bus conductors of two phases. Switchgear.
