Abstract (en)
A switching apparatus for medium voltage electric systems, said switching apparatus comprising one or more electric poles, wherein, for each electric pole, said switching apparatus comprises:- a first pole terminal, a second pole terminal and a ground terminal, said first pole terminal being electrically couplable with a first conductor of an electric line, said second pole terminal being electrically couplable to a second conductor of said electric line and said ground terminal being electrically couplable to a grounding conductor;- a first contact arrangement including a first fixed contact member and a first movable contact member, said first fixed contact member being electrically connected to said first pole terminal and including a first fixed contact, said first movable contact member being electrically connected to said second pole terminal and including a first movable contact, said first movable contact member being reversibly movable along a translation axis, so that said first movable contact can be coupled with or decoupled from said first fixed contact;- a second contact arrangement including a second fixed contact member and a second movable contact member, said second fixed contact member being electrically connected to said ground terminal and including a second fixed contact, said second movable contact member being electrically connected to said second pole terminal and including a second movable contact, said second movable contact member being reversibly movable about a corresponding rotation axis, so that said second movable contact can be coupled to or decoupled from said second fixed contact;- an actuation assembly for actuating the first and second movable contact members of each electric pole during a switching manoeuvre of said switching apparatus, said actuation assembly including an actuation shaft reversibly movable about a corresponding rotation axis;- a motion transmission assembly for transmitting mechanical forces provided by said actuation shaft to the first and second movable contact members of each electric pole.
