Abstract: A load tap changer comprising in part a diverter switch is disclosed. The diverter switch includes a movable main contact (38), first and second fixed main contacts (40a, 40b), a pantograph system (30) for translating a rotational motion of a shaft (22) to a substantially linear motion of the movable main contact. The load tap changer further comprises a link system (10) comprising a gear adapted to be rotated by a motor, a spring battery for storing energy of the motor and a link assembly for coupling the gear to the spring battery. The shaft is coupled to the link assembly to enable the spring battery to rotate the shaft and effect movement of the movable main contact. A predetermined amount of rotation of the shaft effects a movement of the main contact from a contacting position with the first fixed main contact to a contacting position with the second fixed main contact.

Abstract translation: 公开了一种部分包括转向开关的有载分接开关。 切换开关包括可移动主触点（38），第一和第二固定主触头（40a，40b），用于将轴（22）的旋转运动转换成可移动主体的基本线性运动的缩放仪系统（30） 联系。 有载分接开关还包括连接系统（10），其包括适于由电动机旋转的齿轮，用于存储电动机的能量的弹簧电池和用于将齿轮联接到弹簧电池的连杆组件。 轴联接到连杆组件以使得弹簧电池能够旋转轴并且实现可移动主触点的移动。 轴的预定量的旋转影响主触头从与第一固定主触头的接触位置到与第二固定主触点的接触位置的移动。
