Title
(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).
(FR) La présente invention concerne un appareil de commutation (1) destiné à des systèmes électriques moyenne tension, ledit appareil de commutation comprenant un ou plusieurs pôles électriques (2), dont chacun peut être couplé électriquement à une ligne électrique correspondante, ledit appareil de commutation comprenant : - pour chaque pôle électrique, un contact fixe (3) et un contact mobile correspondant (4), ledit contact mobile étant mobile de manière réversible, le long d'un axe de déplacement de translation correspondant (A1), entre une position découplée dudit contact fixe et une position couplée audit contact fixe ; - un ensemble d'actionnement (5) ayant, pour chaque pôle électrique, un arbre d'actionnement (52) tournant autour d'un axe de rotation (A2) pendant une manœuvre de fermeture ou une manœuvre d'ouverture dudit appareil de commutation ; - pour chaque pôle électrique, un ensemble de transmission de mouvement (150) comprenant un mécanisme excentrique (6) couplé fonctionnellement audit arbre d'actionnement (52).
