    • Switching device comprising:
      - a switching unit comprising, for each electric pole, a first disconnection contact, a second disconnection contact and one or more solid state switches;
      - a supporting frame comprising, for each electric pole, a third disconnection contact and a fourth disconnection contact, which are coupled/separated respectively with/from the first and second disconnection contacts, when the switching unit is in an insertion/withdrawn position with respect to the supporting frame;
      - actuating means for moving the switching unit between the insertion position and said the withdrawn position, and viceversa;
      - a control unit comprising control means that are configured to coordinate the operation of the actuating means and the solid state switches, when an insertion/withdrawn operation of the switching unit has to be performed, so that the actuating means move the switching unit only when the solid state switches are in an off-state.
    • 一种切换装置,包括:切换单元,对于每个电极,包括第一断开触点,第二断开触点和一个或多个固态开关; - 对于每个电极,包括第三断开触点和第四断开触点的支撑框架,当切换单元处于相对于第一和第二断开触点的插入/撤回位置时,该第三断开触点和第四断开触点分别与第一和第二断开触点分离地连接/分离 到支架; - 用于在插入位置和所述撤回位置之间移动切换单元的致动装置,反之亦然; - 控制单元,包括控制装置,其被配置为在必须执行切换单元的插入/撤回操作时协调致动装置和固态开关的操作,使得致动装置仅在 固态开关处于断开状态。
