Abstract

PURPOSE: To intend to simplify the structure, by rotating and driving input shaft only in circumference direction at tap changing time, making insulation operating shaft to operate in shaft direction and circumference direction, and doing tap- change.
CONSTITUTION: Rotary disc 20 which is mounted on insulation operating shaft 5 and has a plurality number of revolving rollers that are disposed on the same angle pitch as fixed contactor 7, feeding rotary plate 26 which is fixed on input shaft 18, revolving rollers 22 on rotary disc are inserted, has detachable semi-spherical groove 25 and has feeding rollers 21 which pushes and rotates the revolving rollers on the opposite side circumference to above groove, and intermittent feeding device which is contacted to the disc 20 at the made position of movable contactor on the circumference of this rotary disc 26, pushes the disc until revolving rollers are detached from semi-spere groove of rotary disc against tension of spring 15 and fixes feeding plate that projects convexed part 19a of feeding plate that is moved to shaft direction on a slope are provided. From such structure, insulation operating shaft is driven in shaft direction and rotating direction and tap change can be done, only by rotating input shaft in one direction at one time on the ground.
