(EN) A MEDIUM VOLTAGE SWITCHING APPARATUS
(FR) APPAREIL DE COMMUTATION MOYENNE TENSION
Abstract
(EN) A switching apparatus (1) for medium voltage electric systems, said switching apparatus comprising one or more electric poles (2), each electrically coupleable with a corresponding electric line, said switching apparatus comprising: - for each electric pole, a fixed contact (3) and a corresponding movable contact (4), said movable contact being reversibly movable, along a corresponding translational displacement axis (A1), between a decoupled position from said fixed contact and a coupled position with said fixed contact; - an actuation assembly (5) having, for each electric pole, an actuation shaft (52) rotating about a rotation axis (A2) during a closing manoeuvre or an opening manoeuvre of said switching apparatus; - for each electric pole, a motion transmission assembly (150) including an eccentric mechanism (6) operatively coupled with said actuation shaft (52).
