Abstract
The switching system, preferably suitable for distributing electric energies of medium-high voltage, includes a metal housing which is filled with insulating gas and in which at least one circuit breaker, one isolating switch, one earthing or grounding system and one busbar are arranged. In this arrangement, the contact arrangement of the circuit breaker is located in a housing which is accessible from the outside without intervention in a busbar housing which contains the busbar. This system saves parts and has a small space requirement while its components subject to the most wear are easy to maintain. This is achieved by the fact that the contact arrangement of the isolating switch is provided in the busbar housing and that the housing of the circuit breaker is provided with a housing part of insulating material which penetrates the wall of the busbar housing as a gas-tight current lead-through. In a system of three-phase design, the volume of the busbar housing is additionally reduced by the fact that the three phase conductors of the busbar are helically wound around a common axis.
