Title
(EN) Medium voltage switching apparatus
Abstract
(EN)

A switching apparatus for medium voltage electric systems, the switching apparatus including one or more electric poles, each electrically coupleable with a corresponding electric line, the switching apparatus including: for each electric pole, a fixed contact and a corresponding movable contact, the movable contact being reversibly movable, along a corresponding translational displacement axis, between a decoupled position from the fixed contact and a coupled position with the fixed contact; an actuation assembly having, for each electric pole, an actuation shaft rotating about a rotation axis during a closing manoeuvre or an opening manoeuvre of the switching apparatus; for each electric pole, a motion transmission assembly including an eccentric mechanism operatively coupled with the actuation shaft.
