Abstract

The present invention relates to a bus conductor connection structure for electric field relaxation. The bus conductor connection structure for electric field relaxation includes: an enclosure filled with an inert gas; spacers coupled to two side end portions of the enclosure in a facing contact manner and having connection conductors; conductors provided with predetermined intervals being maintained inside the enclosure; and coupling portions formed in end portions of the conductors, wherein the coupling portion is coupled to the connection conductor in a close contact manner with bolts. Accordingly, the bus conductor connection structure for electric field relaxation is allowed to simply fixing conductors and assembling bolts of a gas insulated bus and to reduce a size of the bus by shortening an insulation distance between the bus and the ground by using a shape and arrangement for electric field relaxation.

First claim

The invention claimed is:

1. A bus conductor connection structure for electric field relaxation, comprising:
an enclosure filled with an inert gas;
spacers coupled to two side end portions of the enclosure in a facing contact manner and having connection conductors;
conductors provided with predetermined intervals being maintained inside the enclosure; and
coupling portions formed in end portions of the conductors,
wherein the respective coupling portion is coupled to the respective connection conductor in a close contact manner with bolts,
wherein the respective coupling portion includes:
a hollow coupling body;
a disc-type flange piece formed in one side end portion of the hollow coupling body, the disc-type flange piece having a plurality of through holes;
a joint portion formed so that the other side end portion of the hollow coupling body is connected to the respective conductor; and
an opening formed by cutting out a portion of the hollow coupling body between the disc-type flange piece and the joint portion.

2. The bus conductor connection structure for electric field relaxation according to claim 1 , wherein the enclosure has a cylindrical shape and is made of a metal, and flanges having a ring shape is formed in the two side end portions of the enclosure.

3. The bus conductor connection structure for electric field relaxation according to claim 1 , wherein a portion of the hollow coupling body where the opening is formed has a semi-cylindrical shape.

4. The bus conductor connection structure for electric field relaxation according to claim 1 , wherein a portion of the hollow coupling body where the opening is formed is arranged to be directed toward a center of the enclosure.

5. The bus conductor connection structure for electric field relaxation according to claim 1 , wherein the hollow coupling body is formed to have a diameter larger than a diameter of the respective conductor.

6. The bus conductor connection structure for electric field relaxation according to claim 1 , wherein the conductors comprise three conductors which are arranged with equal intervals or equal angles inside the enclosure.
