Definitions

  • the invention relates to an insulator for outdoor climate according to the preamble of claim 1.
  • the invention has for its object to get by without an energy supply from an auxiliary network and with significantly lower energy requirements per station to avoid harmful formation of condensation on the insulators.
  • a particularly advantageous solution to the problem with regard to aging and the exact reproducibility of the heating effect can be achieved by using extenders with a much larger loss angle tan 8 than with casting resin, these extenders possibly also having a much lower dielectric constant DK than casting resin to increase the field strengths should.
  • These requirements are e.g. of polyvinyl chloride in the form of granules mixed with the liquid casting resin or by eucryptite as an extender substitute.
  • the amount of the extender is to be measured in such a way that there is sufficient power dissipation in the insulator, which according to available knowledge is 1 to 2 watts per medium-voltage insulator. For other isolators, other performances can prove to be more advantageous.

Claims (5)

1. Isolateur de plein air en résine de coulée, mélangée à des charges économisateurs de résine, caractérisé en ce qu'au moins une partie des charges contient des matériaux finement répartis présentant des pertes électriques internes plus élévées que la résine de coulée, en une quantité telle qu'on évite la formation dommageable d'eau de condensation sur l'isolateur.
2. Isolateur selon la revendication 1, caractérisé en ce qu'il est prévu, pour augmenter les pertes diélectriques internes, des matériaux ayant, par rapport à la résine de coulée, un angle de perte tang b notablement plus important et le cas échéant une constante diélecrique DK sensiblement plus faible.
3. Isolateur selon la revendication 2, caractérisé en ce qu'il est prévu comme charge du chlorure de polyvinyle sous forme de granulé fin.
4. Isolateur selon la revendication 2, caractérisé en ce que de l'eukryptite est prévu comme charge.
5. Isolateur selon l'une des revendications 1 à 4, caractérisé en ce que la proportion de charge, dans l'isolateur, est dimensionnée de telle sorte que dans un isolateur à tension moyenne il apparaît une puissance de perte de 1 à'2 watts.
