Abstract (en)
The present invention relates to magnetic shielding of transformers (100), and particularly to a transformer (100) with at least one magnetic shielding arrangement (101). A transformer (100) with at least one magnetic shielding arrangement (101) is provided, comprising a first magnetic shielding component (102). The first magnetic shielding component (102) is arranged in a first end region (104) of windings (106) of the transformer (100) such that a magnetic stray field and/or stray losses caused by the windings (106) of the transformer (100) during operation of the transformer (100) is reduced. The first magnetic shielding component (102) comprises at least one recess (201, 901, 904, 304) for a better cooling of the transformer (100).
