PURPOSE:To generate no slipping of tap position at the time of switching operation as well as reduce manufacturing cost by connecting two tap-switching devices using a connecting bar and performing tap-switching operation using one set of control bars and a control device. CONSTITUTION:Two tap-switching devices 12A and 12B corresponding to coils of each phase 11U, 11V and 11W are disposed up and down as shown in the figure, connected with each other by a connecting bar 17, and arranged in such a manner that a control bar 15 is rotated by a control device 16 to perform tap-switching operation. In other words, movable contact makers 14A and 14B are mounted on cranckshaft-like driving shafts 18A and 18B each having a certain amount of eccentricity for each center shaft, and the driving shafts 18A and 18B are connected by the connecting bar 17. In this way, since the driving shafts 18A and 18B are connected with each other, rotation of the control bar 15 brings the same operation of the tap-switching devices 12A and 12B. |
