Surge arresters or battery test devices can then also be connected to the cable connector connections as required. 2
  • the object on which the invention is based is to considerably improve the concept of these metal-encapsulated, gas-insulated switchgear assemblies with regard to the structural design and, moreover, to simplify the handling in the event of errors, but without the very advantageous characteristics of these switchgear assemblies with regard to their service life and their high level To limit operational reliability.

Les récipients comportent des traversées pour relier les interrupteurs à trois positions à des barres collectrices disposées en dehors des récipients et des traversées pour relier les sectionneurs de puissance à des raccords de câbles des installations de distribution électriques. Lesdites installations de distribution électriques sont formées de panneaux de couplage (SF) de structure modulaire, qui présentent chacun de premiers espaces de commutation (R1) fermés hermétiquement, qui contiennent des interrupteurs à trois positions (DS) et des barres collectrices (SS) et de seconds espaces de commutation (R2) fermés hermétiquement, qui contiennent des sectionneurs de puissance. Les premiers et les seconds espaces de commutation (R1, R2) sont interconnectés par des dispositifs de couplage modulaire (MK) étanches aux gaz et présentent chacun des traversées de câbles (KD) étanches aux gaz.
