Abstract
The gas-insulated, metal-enclosed switchgear assembly contains two, three or more switchpanels, each having a multipole power breaker (CB.sub.1, CB.sub.2, CB.sub.3, CB.sub.4) as well as isolating and grounding switches per switch pole (CB.sub.1R) and is designed like a ring or in a 11/2 power-breaker circuit. The switch poles of the power breakers are each of identical design and are arranged parallel to one another. The switchpanels each have one current path of U-shaped design per phase in a vertical plane, in which current path the base of the U contains a vertically aligned pole of the power breaker, and the two limbs of the U each contain an electrical connection of the power breaker and an isolating as well as a grounding switch. The upper limbs of the U of one of the switchpanels are connected phase-by-phase to the lower limbs (S.sub.u) of another of the switchpanels, by means of respective single-phase gas pipelines (L.sub.12 (R), L.sub.23 (R), L.sub.34 (Y)) which are arranged inclined to the vertical and are designed in straight lines. Such a switchgear assembly is distinguished by compact construction.
