Definitions

  • nanocomposites can also be used as a field ⁇ gradierendes material when it comes to wrestlers peaks in the formation of electric fields, such as the insulation of electrical conductors to comparable.
  • a material consisting of a polymer can be used for this purpose.
  • a filler is distributed whose Parti ⁇ kel are nanoparticles, so have a mean diameter of at most 100 nm.
  • AI semiconducting materials are used for such nanoparticles, inter alia, whose band gap is in a range of 0 eV and 5 eV.
  • the impregnation consists of a polymer which is crosslinked from a negative ionomer, in particular PSS, and a positively charged ionomer.
  • a positively charged ionomer preferably PEDOT or PANI can be used.
  • PEDOT refers to the already mentioned poly (3, 4-ethylene-dioxydthiophene).
  • PANI is polyaniline and PSS is polystyrene sulfonate.
  • the use of negatively charged and positively charged ionomers allows beneficial ⁇ way a particularly simple production of the Cellulosemateri- as.
  • the ionomers can be easily dissolved in water and thus fed to the process of making the cellulosic material, which is also water-based.
  • Vernet ⁇ wetting the ionomers following the preparation of the Cellu ⁇ loose material the resistivity of the cellulose material ⁇ can be lowered.
  • the ionomers polymerize and form in the cellulosic material an electrically conductive network which is responsible for the reduction of the specific resistance.
  • the ge ⁇ can called ionomers also be used to encase semiconducting already mentioned or non-conductive nanoparticles.
  • the electrode tube may be dimensioned in length such that it can be arranged with its ends between two adjacent HVDC transformer coils or HVDC choke coils.
  • This has the advantage that both the one coil and the other coil out a tolerance compensation arises, which is formed by the respective gap between the ends of the electrode tube and the Benach ⁇ disclosed coil.
  • the arrangement of the electrode ⁇ tube between the coils is advantageously simplified according to the invention, since it can be carried out by using the cellulose material according to the invention space-saving and therefore fits in the space remaining between the coils.
  • a winding layer is dependent on the paper thickness, while the already mentioned layer layer is dependent on which region should be equipped with which specific resistance.
  • layers of different resistivity can be made by using different papers.
  • a winding layer is generally much thinner (because of the paper thickness) as a layer layer.
  • a layer layer is thus produced by winding a plurality of winding layers.
  • the thickness s of the layer is reduced in comparison with the required thickness when using the relevant untreated cellulose material instead of the composite. This is an advantageous possibility, such as the constructive freedom of design, which is characterized by the Reduction of the resistivity of the envelope results, can be exhausted. Due to a smaller thickness of the envelope, the space required for the line feedthrough is advantageously reduced. Due to the reduced specific resistance see the dielectric strength of the layer remains the same.

Abstract

L'invention concerne un guide de conduites (28) pour des conduites électriques (29) de transformateurs de transmission de courant continu haute tension (22) ou de bobines de réactance de transmission de courant continu haute tension. Selon l'invention, au moins la couche isolante (30) d'un tube à électrodes (21) et de préférence les barrières aux solides (26, 32) sont réalisées dans un matériau cellulosique dont la résistance spécifique est réduite par un traitement par rapport à celle de matériau cellulosique non traité, et se rapproche donc de la résistance spécifique de l'huile pour transformateur. Ainsi, il est possible de fabriquer des lignes d'isolation (25) peu encombrantes et résistantes au percement pour lesdits composants de transmission de courant continu haute tension, ce qui augmente avantageusement la marge constructive pour la conception des guides de conduites.
