    • A vacuum switch means a unit switch section comprising a pair of vacuum main circuit switches, an earth switch, operating rods for operating movable conductors of the main circuit vacuum switch and earth switch, and a molding case covering the main circuit switch , earth switch and the operating rods, wherein the operating rods are connectable with an operating mechanism, and the fixed conductors of the main circuit switch and earth switch are connected with bushing conductors. The main circuit vacuum switches are disposed in separate vacuum chambers. The movable conductors of the main circuit switches are electrically connected to each other via a transition conductor, and the movable conductors are operated synchronously by means of a transition rod connected to the transition conductor.
    • 真空开关是指包括一对真空主电路开关,接地开关,用于操作主电路真空开关和接地开关的可动导体的操作杆的单元开关部分,以及覆盖主电路开关,接地开关和 操作杆,其中操作杆可与操作机构连接,并且主电路开关和接地开关的固定导体与衬套导体连接。 主电路真空开关设置在独立的真空室中。 主电路开关的可动导体经由过渡导体彼此电连接,并且可移动导体通过连接到过渡导体的过渡棒同步地操作。

    • An electromagnetic operation device, comprising electromagnetic operators 4 each paired with a vacuum valve 1 of each phase of three phases, is equipped with main shafts 2 that can operate independently for each phase and a three-phase connecting shaft 3 that synchronizes the operation of the three phases in accordance with the operation of each main shaft. The rod 44 of the electromagnetic operator 4 is connected with the blade 45 of the main shaft 2 at the fulcrum 46 and the blade 47 of the three-phase connecting shaft 3 is connected with the blade 45 of the main shaft 2 by the linkage 7. The motion of a main shaft 2 that has operated quicker than the others is transmitted to the other main shafts via the three-phase connecting shaft 3 so as to synchronize the operation of the three phases.
    • 电磁操作装置,包括与三相各相的真空阀1配对的电磁操作装置4,配备有能够对各相独立运转的主轴2以及使相位相反的运转同步的三相连结轴3 按照每个主轴的运行三相。 电磁操作器4的杆44在支轴46处与主轴2的叶片45连接,三相连接轴3的叶片47通过连杆7与主轴2的叶片45连接 通过三相连接轴3使主轴2的动作比其他动作更快地运动到其他主轴,以使三相的动作同步。
