SWITCHGEAR DEVICE WITH GROUNDING UNIT

摘要

A gas-insulated switchgear device, comprising at least an input bar and an output bar which are positioned inside two corresponding bushings, an enclosure which contains an interruption unit and a disconnection unit which are electrically connected to each other and, respectively, to the input bar and to the output bar, and a grounding unit having electrical and mechanical coupling means which are associated with the output bar, and contact means movable between a first position in which they are disconnected from said coupling means and the output bar is energized, and a second position in which they are connected to the coupling means and the output bar is grounded, the contact means being operatively controlled by actuation means which are suitable to supply the energy required for movement.
