Compressed gas insulated high voltage switching installation with single phase metallic encapsulation

Claim 1

In a compressed gas insulated high voltage switching installation with a metallic encapsulation, including bus bar systems and switchgear sections at least one of which is firmly anchored in space and in which compensators with tie rods are arranged in line with the bus bar systems, the improvement comprising: (a) all branches of the switchgear sections in the installation firmly anchored in space; (b) each phase of the bus bar systems being subdivided into sections alternately lying along two parallel longitudinal axes in such a manner that between three respective successive branches at least two successive sections having different longitudinal axis are disposed; (c) double T-shaped connecting housings, having parts aligned with said two axes and a cross piece connecting said parts with inner and outer connecting flanges at the ends of the parts aligned with said axes, disposed between and coupled to adjacent sections of the same phase, said double T-shaped housings firmly anchored in space; (d) a compensator for each section of the bus bar, arranged at the ends said inner and outer connecting flanges at one of the two connecting housings disposed at opposite ends of said section; and (e) tie rods extending from the outer flange of each compensator to its inner flange bridging said compensators and said connecting housing part.
