A Tap Changer Arrangement And A Transformer Arrangement Comprising The Tap Changer Arrangement

Abstract: A tap changer arrangement (10) comprising a tap changer housing (12) having a longitudinal extension along a first axis (A), which tap changer housing (12) comprises a first interface part (14), at a proximal part of the tap changer housing (12), fixedly attachable to a support structure (16) of a transformer tank (38), a second interface part (18) at a distal part of the tap changer housing (12), and an intermediate housing part (20) arranged between the first interface part (14) and the second interface part (18), the first interface part (14), the intermediate housing part (20) and the second interface part (18) being arranged on the first axis (A). The tap changer arrangement (10) comprises a plurality of support elements (24), whereby the plurality of support elements (24) is mechanically connected to the second interface part (18) and either mechanically connected to the first interface part (14) or arranged to be mechanically connected to a support structure (16) of the transformer tank (38), the plurality of support elements (24) being configured to exert a compressive force on the intermediate housing part (20) from the first interface part (14) and from the second interface part (18) such that the intermediate housing part (20) is pre-tensioned between the first interface part (14) and the second interface part (18).
