Regulating windings of on-load tap changing regulator and pin configuration thereof

The invention relates to the technical field of regulating winding structures and particularly discloses regulating windings of an on-load tap changing regulator and a pin configuration thereof. The regulating windings of the on-load tap changing regulator and the pin configuration thereof comprise a regulating winding A next to a magnetic limb and are characterized in that an oil channel A, a paper tube and an oil channel B are sequentially formed in the outer side of the regulating winding A, and a regulating winding B is arranged on the outer side of the oil channel B, wherein the winding direction of the regulating winding A is right, the winding direction of the regulating winding B is left, and an upper end outlet terminal of the regulating winding A and a lower end contact terminal of the regulating winding B are correspondingly connected and then guided to a tap switch. The regulating winding structure and the pin configuration design thereof which are simple in structure, beneficial for line outgoing
