Definitions

  • the present disclosure generally relates to electromagnetic induction devices such as transformers and reactors, and in particular to electromagnetic induction devices having foil windings.
  • Electromagnetic induction devices such as transformers and reactors, are used in power systems for voltage level control.
  • a transformer is an electromagnetic induction device used to step up and step down voltage in electric power systems in order to generate, transmit and utilize electrical power in a cost effective manner.
  • a transformer has two main parts, a magnetic circuit, the core, made of e.g. laminated iron and an electrical circuit, windings.
  • foil windings such as aluminium or copper foil windings have unique advantages compared to wire windings due to their simplicity of manufacturing, their improved transient voltage distribution and superior short circuit fault withstand-ability.
  • the usage of foil windings is limited to smaller rating power transformer due to uneven current distribution caused by fringing of the magnetic leakage flux at the ends of the foil winding. This results in high eddy losses and high temperature developments in the foil winding. The problem becomes worse with high leakage flux magnitude as the power rating increases.
  • GB990418 A discloses an electrically conducting shield structure for an electrical apparatus having a core and one or more foil windings to reduce current concentrations at the edges of the windings, caused by radial flux leakage, by establishing a magnetic field adjacent to the surface of each winding in opposition to the radial component of flux passing through the winding. Shields are arranged between the L.T. winding and core and surrounding the H.T. winding.
  • GB990418 may reduce eddy current losses, it would however be desirable to further reduce eddy current losses in foil windings to be able to increase power ratings for electromagnetic induction devices utilising foil windings.
  • An object of the present inventive concept is to provide electromagnetic induction devices which solve or at least mitigate the problems with existing solutions.
  • an electromagnetic induction device comprising a magnetic core having a limb, a foil winding wound around the limb, wherein the foil winding has a first end portion at a first axial end of the foil winding and a second end portion at a second axial end, opposite to the first axial end, of the foil winding, wherein each of the first end portion and the second end portion of the foil winding is provided with a plurality of cut-outs along the circumference of the foil winding.
  • An effect which may be obtainable thereby is that the current may be more evenly distributed in the foil winding. This may in particular be obtainable due to that the electrical resistance at the lateral ends of the foil winding is increased because of the cut-outs. The current distribution may thereby be more centred towards the middle section of the foil winding.
  • the foil of each turn of the foil winding is provided with the cut-outs.
  • the cut-outs are in the form of a plurality of through-openings.
  • the cut-outs have a circular or elliptical shape.
  • the first end portion and the second end portion each has a plurality of rows of the through-openings, wherein the rows extend longitudinally parallel with the circumferential direction of the foil winding, and wherein the dimension of the through-openings of the first end portion increases with each row towards the first axial end of the foil winding and wherein the dimension of the through-openings of the second end portion increases with each row towards the second axial end of the foil winding.
  • the cut-outs are extending from the edge of the first axial end towards the centre of the foil winding, and wherein the cut-outs are extending from the edge of the second axial end towards the centre of the foil winding.
  • the cut-outs are triangular-shaped, trapezoidal-shaped, or define a wave-like pattern in the circumferential direction of the foil winding.
  • the first end portion and the second end portion each has a plurality of rows of cut-outs, wherein each row extends longitudinally along the circumferential direction of the foil winding, and wherein each pair of adjacent rows are overlapping axially and are displaced relative to each other in the circumferential direction of the foil winding.
  • an electromagnetic induction device comprising a magnetic core having a limb, a foil winding wound around the limb, a busbar, first connectors, second connectors and third connectors, wherein the foil winding is subdivided into a plurality of main sections that are electrically parallel connected, wherein the plurality of main sections include a central main section connected to the busbar by means of the first connectors, a first main end section connected to the busbar by means of the second connectors and a second main end section connected to the busbar by means of the third connectors, wherein the total impedance of the first main end part and the second connectors and the total impedance of the second main end part and the third connectors is larger than the total impedance of the central main section and the first connectors.
  • An effect which may be obtainable thereby is that the current may be more evenly distributed in the foil winding. This may in particular be obtainable because of the higher total impedance at the two end sections of the foil winding. This results in that the current distribution may be increased towards the central main section.
  • the first main end section is subdivided into a plurality of first end sections, wherein the first end sections are electrically parallel connected.
  • the second main end section is subdivided into a plurality of second end sections, wherein the second end sections are electrically parallel connected.
  • the plurality of main sections include a central main section, a first main end section and a second main end section, wherein the central main section is made of copper foil, and the first main end section and the second main end section are made of aluminium foil.
  • the high resistance of the aluminium foil pushes down the current to the central copper foil.
  • the eddy current loss at is thus reduced due to the high resistance of the aluminium foil.
  • the length proportion of the aluminium and copper can be decided based on the resistivity ratio of aluminium and copper, i.e. ⁇ al / ⁇ cu , and the flux distribution to arrive at fairly uniform current distribution.
  • This disclosure covers two main aspects of an electromagnetic induction device which has a magnetic core with a limb, and a foil winding wound around the limb. Both aspects provide a more even current distribution along the axial direction of the foil winding.
  • the first aspect obtains this effect by means of a subdivision of the foil winding in the axial direction, thus obtaining a plurality of main sections.
  • subdivided is here mean that the main sections are physically separated from each other, and may be seen as a plurality of discs arranged along the longitudinal direction of the limb.
  • the main sections are electrically parallel connected.
  • the second aspect obtains this effect by means of cut-outs provided in the foil winding, in particular in the foil constituting the foil winding, and which cut-outs are arranged along the tangential direction of the foil winding.
  • the cut-outs extend through the foil.
  • the cut-outs are arranged only along the two end portions of the foil winding. Due to the cut-outs the electrical resistance is increased in the two end portions of the foil winding, where eddy current losses are the greatest, and the current distribution in the foil winding may become more uniform.

  • the first main end section 11b may be subdivided into a plurality of first end sections 13a, 13b.
