摘要： A coil for a transformer assembly is provided. The coil extends circumferentially around a longitudinal axis. The coil comprises a foil winding arrangement and a conductor element. The foil winding arrangement extends circumferentially around the longitudinal axis and has four edge regions. The conductor element covers at least partially at least one of the edge regions of the foil winding arrangement. The conductor element allows for a reduction in an electric field that arises during an operation of the transformer assembly at the edges of the foil winding arrangement. In this manner, a performance improvement in partial discharge tests and lightning impulse tests can be achieved.

摘要： The proposed transformer includes windings made of a multi-layer ferromagnetic foil tape having an even number m of ferromagnetic layers, coated by interlayer insulation. The winding's upper ends are connected through a first yoke, the winding's bottom ends are connected through a second yoke. Each winding is wrapped by a short-circuited coil, and contains a component for transposition of layers connected in a break at the middle of tape. The insulation's thickness is determined by a ratio of di>un2,pic*/(En2,pic·m), where u2,pic is a maximum peak voltage between adjacent winding turns, En2,pic is a maximum electric field strength of the insulation. The insulation uses either ferroelectric material Fe2O3, or multi-layered material with an intensive antiferromagnetic interaction formed as a plurality of pairs of alternating layers of Cu—Fe with a ratio of thicknesses of Cu and Fe ranged from 5:1 to 10:1.
