Abstract

The present disclosure relates to a gas insulated switchgear (GIS), and more particularly, a structure of a bus in a GIS. A structure of a three-phase integrated bus in a GIS, in a bus of a gas insulated switchgear comprising an enclosure, three phase conductors inserted in the enclosure, and spacers coupled to both sides of the enclosure to fix the three phase conductors, is characterized in that the three phase conductors are arranged in a shape of inverted triangle, wherein a conductor located at a lower side, of the three phase conductors, is formed in a shape of straight pipe, and has a branch bus upwardly extending from its middle portion, and wherein each of two conductors located at an upper end of the inverted triangle, of the three phase conductors, has both side portions formed in a shape of straight pipe and a middle portion outwardly curved.

First claim

What is claimed is:

1. A structure of a three-phase integrated bus in a gas insulated switchgear (GIS), the structure comprising an enclosure, three phase conductors inserted in the enclosure, and spacers coupled to both sides of the enclosure to fix the three phase conductors,
wherein the three phase conductors are arranged in a shape of inverted triangle with respect to a specific orientation,
wherein one of the three phase conductors is entirely located in a lower position than the other two of the three phase conductors with respect to the same specific orientation,
wherein the one of the three phase conductors that is entirely located in the lower position is formed in a shape of straight pipe, and has a branch bus upwardly led out from its middle portion with respect to the same specific orientation, and
wherein each of two conductors located at an upper end of the inverted triangle, of the three phase conductors, has both side portions formed in a shape of straight pipe and a middle portion outwardly curved in opposite directions from the branch bus with respect to the same specific orientation such that the branch bus extends between the two conductors.

2. The structure of claim 1 , wherein the enclosure is formed in a cylindrical shape, wherein each of a left side portion and a right side portion of the enclosure has a transverse section with a diameter shorter than that of a transverse section of a middle portion of the enclosure with respect to the same specific orientation.

3. The structure of claim 1 , wherein the middle portion of the enclosure has a circular or oval cross section, and is outwardly curved to be convex from the cylindrical body of the enclosure with respect to the same specific orientation.
