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.

Abstract: A disconnector for a metal encapsulated, gas insulated high voltage switchgear includes a housing with at least a first and a second axis which intersect at a first angle. The disconnector also includes two contact carriers that are arranged on the first axis and are positioned between to contact carriers at an isolating distance by securing elements. The first axis and the second axis each form an axis of symmetry of the housing. The housing has four openings which are provided with flanges and which have the same diameter and centers located on one of the first and second axes, and are arranged at the same distance from the intersection point of the first and second axes.

Abstract: A metal-encapsulated, gas-insulated switching installation is provided with at least one busbar system, the busbar system having an axis separation, and a circuit breaker, the circuit breaker being in the form of a pole and having a pole axis, the circuit breaker including at least one quenching chamber installed in a pole enclosure and at least one connection for the associated busbar system. The pole axis is arranged at a right angle to a surface of a foundation. The circuit breaker of the switching installation includes a modular circuit breaker pole.

Abstract: A metal-enclosed, gas-insulated switching installation includes at least two busbar systems and a circuit breaker. Each circuit breaker is in the form of a pole having a pole axis and at least one extinction chamber, installed in a pole housing. The pole axes are arranged perpendicularly to a foundation and are located in a first plane. The switching installation includes an electrically conductive connection, extending along a connecting axis, of the voltage-carrying extinction chamber of the circuit breaker to each of the busbar systems and an isolator arranged in the connection between the busbar and the circuit breaker pole.

Abstract: A high-voltage switching device for gas-insulated switchgear has a gas-filled metal housing, a conducting path in the metal housing and at least two series-connected switching points with movable contact pieces which are actuated by a common drive mounted on the metal housing. The conducting path forms an angle with at least one of the switching points respectively arranged on each leg of the angle, the device thereby requiring less space in the case of both vertical and horizontal installation.
