A selector for an on-load tap changer with a diverter switch includes: an insulating plate with a first side and a second side, the second side opposite the first side; a plurality of fixed contacts, which extend from the first side through the insulating plate to the second side; a first movable contact on the first side; a second movable contact on the second side; a first connection, which is connected with the first movable contact and which is connectable with a first branch of the diverter switch; and a second connection, which is connected with the second movable contact and which is connectable with a second branch of the diverter switch. Each of the first moveable contact and the second movable contact are selectably connectable with each of the fixed contacts.

Selector for an on-load tap changer and on-load tap changer with load transfer switch and selector

The invention relates to an on-load tap-changer () having a switching tube (), an energy accumulator () for adjusting a switch position of the switching tube (), a detector () for detecting a switch position of the on-load tap-changer (), and an on-load tap-changer mechanism (). The switching tube () and the detector () are both mechanically coupled to the energy accumulator () via the on-load tap-changer mechanism ().

On-load tap changer

An on-load tap changer has a switching tube, an oil suction pipe arranged centrally and coaxially along an axis inside the switching tube, and a kerosene drain screw so mounted in a base of the on-load tap changer that it is coaxial with an axis of the oil suction pipe, with the axis of the switching tube, and with an axis of the on-load tap changer. A bearing ring is so acted on by a resilient element at one side and radially with respect to the axis of the on-load tap changer that the switching tube and the oil suction pipe both mechanically positively cooperate with the bearing ring and are centered about the axis of the on-load tap changer.
