Title
(EN) MEDIUM VOLTAGE SWITCHING APPARATUS.
(ZH) 中压开关设备
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).
(ZH) 一种用于中压电气系统的开关设备(1),所述开关设备包括一个或多个电极(2),每个电极可与对应的电线电耦合,所述开关设备包括:‑对于每个电极,固定触头(3)和对应的可动触头(4),所述可动触头可沿着对应的平移位移轴线(A1)在与所述固定触头解耦的解耦位置和与所述固定触头耦合的耦合位置之间可逆地移动;‑致动组件(5),对于每个电极,所述致动组件具有在所述开关设备的闭合操纵或断开操纵期间绕旋转轴线(A2)旋转的致动轴(52);‑对于每个电极,传动组件(150),所述传动组件包括与所述致动轴(52)操作性地联接的偏心机构(6)。
