Structure of three-phase integrated bus in gas insulated switchgear

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.
