| 摘要 |
The invention relates to a transformer winding (10, 40, 60, 80), comprising at least two hollow cylindrical, multi-layer winding modules (12, 14, 42, 44, 46, 48, 64, 66), which are nested in each other and which extend around a common winding axis (18, 50, 62, 82) and which are connected electrically in series, and at least one cooling channel (16, 52, 68, 90), which is arranged along the same winding axis (18, 50, 62, 82) in a hollow cylindrical manner between the winding modules (12, 14, 42, 44, 46, 48, 64, 66). A planar electrical shield (20, 22, 54, 56, 58, 72, 74, 92, 94) extending over approximately the entire axial length is provided inside the at least one cooling channel (16, 52, 68, 90) at least in some sections along the radial circumference of said cooling channel. The electrical capacitance distribution in the transformer winding connected electrically in series is influenced by said planar electrical shield.
