Abstract
A metal-enclosed, gas-filled switchgear unit has at least two busbar systems and a circuit breaker which respectively has per pole a pole axis and at least one arcing chamber built into a pole housing constructed as a metal enclosure. The pole axes are arranged perpendicular to a foundation and lie in a first plane. Furthermore, the switchgear unit respectively has an electrically conductive connection, extending along a connecting axis, between the live arcing chamber of the respective pole and each of the busbar systems. A metal-enclosed, gas-filled switchgear unit is provided in which the insulation and the fastening of the arcing chambers of the circuit breaker poles are substantially simplified and reduced in cost. The arcing chamber is connected in a force-closed fashion to the at least two current terminals and the arcing chamber is positioned by these alone in the metal enclosure.
