Abstract
There is provided a tap changer in which movable contacts rotate to be selectively connected to a plurality of taps. The tap changer includes a rotatable upper movable contact; a rotatable lower movable contact electrically connected to the upper movable contact; a driving shaft rotating the upper movable contact and the lower movable contact integrally; a single-type fixed contact including a single terminal connected to any one of a plurality of taps; and a dual-type fixed contact including a first terminal and a second terminal connected together to another of the plurality of taps. Since the upper movable contact and the lower movable contact are integrally rotated through the single driving shaft, the number of components and volume of the device may be reduced and an operation of the device may be facilitated.
