Abstract
Abstract An outdoor high-voltage switchgear assembly comprising rigid sectionalized busbars provided with busbar compensators made of flexible current-conducting members mounted on insulated supports through the use of bases having an open configuration and electrical apparatuses connected through branches to said sectionalized busbars, each base being composed of legs forming said open configuration in such a way that it is almost U-shaped, wherein said legs are placed in planes parallel to longitudinal axes of the sectionalized busbars, and the base is secured on the insulated support so that the ends of the base legs are higher than the horizontal plane going through the point common for both legs, each busbar compensator being secured by its ends to adjacent sections of the sectionalized busbars, which are attached at the ends of said base legs, and positioned between the longitudinal axes of these legs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
An outdoor high-voltage switchgear assembly comprising: rigid sectionalized busbars; busbar compensators made of flexible current-conducting members connected to said rigid sectionalized busbars; bases of an open configuration mounting in said rigid sectionalized busbars; insulating supports carrying said bases; electrical apparatuses connected through branches to said rigid sectionalized busbars; said bases, each of them having legs forming said open configuration which is substantially U-shaped, said legs being positioned in the planes parallel to the longitudinal axes of the rigid sectionalied busbars, each base being secured on said insulating supports so that the ends of the base legs are higher than the horizontal plane going through the point common for said legs, each said busbar compensator being fastened by its ends to the adjacent sections of the rigid sectionalized busbars, which are secured on the ends of said legs of the base and positioned between the longitudinal axes of these legs.
Claim 2
Dependent Claim
149 words
An outdoor high-voltage switchgear assembly comprising: rigid sectionalized busbars; busbar compensators made of flexible current-conducting members connected to said rigid sectionalized busbars; bases of an open configuration mounting in said rigid sectionalized busbars; insulating supports carrying said bases; electrical apparatuses connected through branches to said rigid sectionalized busbars; said bases, each of them having legs forming said open configuration which is substantially U-shaped, said legs being positioned in the planes parallel to the longitudinal axes of the rigid sectionalied busbars, each base being secured on said insulating supports so that the ends of the base legs are higher than the horizontal plane going through the point common for said legs, each said busbar compensator being fastened by its ends to the adjacent sections of the rigid sectionalized busbars, which are secured on the ends of said legs of the base and positioned between the longitudinal axes of these legs.
Claim 3
Dependent Claim
