PROBLEM TO BE SOLVED: To make an on-load tap changer compact with simple configuration.SOLUTION: A diverter switch comprises: a current-limiting resistor connected between a third movable contact and a neutral; a resistance vacuum valve connected between the current-limiting resistor and the neutral; a main vacuum valve connected between a fourth movable contact and the neutral; a drive shaft 110 extending linearly and rotating with a driving force supplied externally; and a force accumulating mechanism having the input side coupled with the drive shaft 110. The drive shaft 110 extends to penetrate the force accumulating mechanism. When viewed from the force accumulating mechanism side, a first auxiliary switch is located on the second auxiliary switch side. The third movable contact of the first auxiliary switch is coupled to an input shaft 110a. The fourth movable contact of the second auxiliary switch is coupled to the output side of the force accumulating mechanism. |
