ABSTRACT:
This metal-enclosed, gas-insulated switchgear assembly is provided with at least one multiphase switch panel which is mounted on a foundation surface (8), with in each case at least one power breaker (1, 2, 3) per phase which extends along a longitudinal axis (4, 5, 6), these longitudinal axes (4, 5, 6) being arranged in a first plane, with at least one busbar system which is arranged in at least a second plane and extends along busbar axes (13, 14, 15) and in which the busbar axes (13, 14, 15) have a distance (s) between them. The distance between centers between a first connecting stub (16, 17, 18) and a second connecting stub (25, 26, 27) of the power breaker (1, 2, 3) is at least three times and at most four times as great as the distance (s) between the busbar axes (13, 14, 15). The power breakers (1, 2, 3) may be arranged offset and aligned in a row, resulting in very compact switch panels.
