ABSTRACT:
A load tap changer (LTC) 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; and a link system (10) comprising a gear (12) adapted to be rotated by a motor, a spring battery (26) for storing energy of the motor, link means (14, 16, 18) for coupling the gear to the spring battery, and the shaft (22) coupled to the link means, wherein the spring battery is operable to rotate the shaft and to thereby effect the movement of the movable main contact. A predetermined amount of rotation of the shaft effects a movement of the movable main contact from a contacting relation with the first fixed main contact to a contacting relation with the second fixed main contact.
