  • the use of a switching device in the interior of an encapsulating housing as earthing switch is providable. This makes it possible, for example, to apply individual earth conductors / conductor elements inside the capsule housing of a switching field to ground potential.

Abstract

L'invention concerne un système de couplage comprenant un organe de couplage électrique (1, 1a, 1b). L'organe de couplage (1, 1a, 1b) est équipé d'une première pièce de contact de couplage (2) ainsi que d'une seconde pièce de contact de couplage (3). Les deux pièces de contact de couplage (2, 3) sont mobiles l'une par rapport à l'autre et forment une distance de coupure (9) électriquement isolante. La distance de coupure (9) est entourée d'une enveloppe (7) électriquement isolante. L'une au moins des pièces de contact (2, 3) peut être actionnée au moyen d'un système d'actionnement fluidique.
