Title:
ON-LOAD TAP CHANGER
Document Type and Number:
Japanese Patent JP2017168775
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an on-load tap changer capable of preventing such a situation that the output torque of an accumulating drive mechanism for operating a switch, opening and closing at the time of tap change, is insufficient.SOLUTION: In an on-load tap changer for converting the displacement of a slider, energized to slide by a spring provided in an accumulating mechanism, into rotary motion transmitted to a crank plate 20, and driving force is transmitted from the crank plate to a switch, multiple drive rollers r1-r5 are attached to the slider 5, a driven part including a roller contact surface having roller contact regions Sc1-Sc8, coming into contact with any one of the multiple drive rollers in the process when the slider displaces, is provided on the crank plate 20 side, and the magnitude of operation torque obtained at each rotary angle position of the crank plate can be set appropriately, by replacing the drive roller coming into contact with the roller contact surface of the driven part in the process when the slider displaces.SELECTED DRAWING: Figure 1
