    摘要： The invention relates to a switching arrangement (15) with a pre-selector (28) for a power transformer (10, 40) which has multiple windings (12, 14). The pre-selector is designed to optionally connect at least one first winding (12) to one of the two end contacts (30, 32) of at least one second winding (14). At least one first switch is arranged in the connection between the preselector (28) and the first winding (12), thereby allowing the pre-selector to be switched in an arc-free manner and thus in a gas-free manner as well.

    摘要： The invention relates to a selector switch (1) for tap-changing transformers. The selector switch (1) has a tap selector (37) in the oil tank (18) of said selector switch (1). In accordance with the invention, two separate zero contacts (73, 74) belong to each phase (L1, L2, L3) to be switched by the tap selector (37). The zero contacts (73, 74) are each arranged on a wall (17) of the oil tank (18) and reach through the wall (17). The invention also relates to a support arm (62) of a tap selector (37) of a selector switch (1). The support arm (62) has a first lateral rib (65) and a second lateral rib (66) and at least one web-like elevation (67) extending along a length (L) of the support arm (62) is formed between the first lateral rib (65) and the second lateral rib (66).
