Claims

[Scope of utility model registration request]

Two windings of a current limiting reactor that share a common magnetic path with one terminal connected to each of a pair of movable contacts that sequentially and alternately select adjacent tap terminals of the tap selector; An auxiliary switching switch comprising a pair of fan-shaped plate-shaped stationary contacts each connected to a terminal, and two sets of split-type movable contacts that are rotated by a predetermined angle by a drive shaft and come into sliding contact with the stationary contacts; A load switch is connected between a pair of fixed contacts, and the switching operation is performed based on a predetermined order and timing, in which the split movable contact moves over a predetermined radius on both sides of the fixed contact. A roller-shaped movable arc contact is provided which is rotatably supported on a radius different from the main contact and which is in sliding contact with the main contact. A U-shaped groove is formed, and a fixed arc contact protrudes in a trapezoidal shape from the bottom of the circumferential end of the groove, and when the movable arc contact rides on the fixed arc contact, the 1. A reactor-type tap switching device under load, characterized in that a main contact and the fixed contact are formed so as to be separated from each other.
