摘要

1. Oil-immersed tap selector for tap switches of tapped transformers, in which the individual tap contacts (4) sit on insulating rods (3) arranged in a circle and in which the insulating rods (3) are screwed to an upper (1) and a lower (2) cage ring, while the fastening screws (5) of the insulating rods and the connecting tags (6) of the tap contacts are surrounded by special control electrodes (7, 9, 91), characterised thereby, that insulating, again detachable shaped parts (8, 10, 11), particularly of presspan, are arranged shapelockingly around the control electrodes (7, 9, 91).
