Document Type and Number:
Japanese Patent JP6379192
Kind Code:
B2
Abstract:
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.
