Definitions

  • the objective of the present invention is to provide a power transformer or inductor comprising a flexible conductor having electric field containing means as well as inner electric field equalizing means, which presents a design which is technically favourable and allows a high space factor.
  • the invention is made possible by the use of said flexible conductor in at least a part of the winding or windings in the power transformer /inductor.
  • An example of a flexible conductor having electric field containing means is a flexible XLPE-cable of the sort used for power distribution.
  • Such a cable comprises a conducting core, a first semiconducting layer provided around said conducting core, a solid insulation layer provided around said first semiconducting layer and a second semiconducting layer provided around said insulation layer.
  • Fig. 1 is a simplified view showing the electric field distribution around a winding of a conventional power transformer or inductor.
  • Fig. 3 is a simplified view showing the electric field distribution around a winding of a power transformer or inductor according to a first preferred embodiment of the invention.
  • Figure 1 shows a simplified view of the electric field distribution around a winding of a conventional power transformer or inductor with a winding 11 and a core 12.
  • equipotential lines 13 that is, lines where the electric field has constant magnitude.
  • the lower part of the winding is assumed to be at ground potential and the upper part is assumed to be connected to a line terminal.
  • the potential distribution determines the composition of the insulation system since it is necessary to have sufficient insulation both between adjacent turns of the winding and between turns of the winding and grounded details surrounding the winding.
  • the equipotential lines 13 in the figure shows that the upper part of the winding is subjected to the highest insulation loads.

Abstract

L'invention concerne un transformateur d'alimentation ou un inducteur. L'enroulement (31) du transformateur/inducteur est constitué d'un conducteur souple (38) doté de moyens de rétention d'un champ électrique. Ces moyens permettent de maintenir le champ électrique, dû au courant électrique circulant dans l'enroulement (31), dans la couche isolante du conducteur souple (38). L'épaisseur de la couche isolante du conducteur souple (38) est choisie de sorte que la contrainte électrique (33) soit constante sur toute la longueur de l'enroulement. La section transversale de la couche isolante du conducteur souple (38) est ainsi optimisée, ce qui permet de concevoir un transformateur/inducteur à facteur d'encombrement élevé.
