  • Multiphase switching system and generator arrangement having such a switching system
    Patent number: 5334927
    Abstract: In the case of the multiphase switching system (1), each (for example L.sub.3) of the phase conductors is arranged in the course of a generator output line (2), which is arranged between a generator (7) and a network transformer (8), together with a switching apparatus, in encapsulation (5) which is insulated by air gaps, in a manner isolated from the other phase conductors.The switching system is intended to allow virtually all the switching, protection, and measurement functions occurring in a generator arrangement to be executed despite a compact and space-saving construction.This is achieved by the switching apparatus (three-position interrupter switch 10) having at least two switching positions. A first of these two switching positions is arranged between the generator (7) and an output of the switching system (1) which acts on the network transformer (8).
