Definitions

  • the surge arrester is advantageously characterized in that at a nominal DC voltage of 230 V, the Anschschschreib is lower than 500 V and the Parameters for the nominal alternating current and the rated impulse current between each side electrode with respect to the center electrode are symmetrical and equal. Even if the nominal DC response voltage varies by +/- 20%, the surge arrester advantageously records a response surge voltage lower than 500V.
  • the distance A in the longitudinal direction is greater than the distance C in the radial direction, but smaller than the distance B.
  • FIG. 5 shows a surge arrester according to FIG. 4 whose center electrode has a welded-on shorting bar 12 which is insulated from the side electrodes by means of a foil 13.
  • the shorting bar is made of CuBe, the film is Hostaphan® or polypropylene.

Claims (12)

  1. Parasurtenseur présentant deux électrodes latérales (2, 3) qui s'étendent dans un espace intérieur formé au moyen d'au moins un corps isolant (4) et d'une électrode centrale (5),
    caractérisé en ce que
    la distance frontale (A) entre les électrodes latérales (2, 3) est supérieure aux distances (C) entre chacune des électrodes latérales (2, 3) et l'électrode centrale (5) et
    en ce que la distance (A) entre les électrodes latérales (2, 3) est plus petite que la distance (B) entre les parties d'extrémité de l'électrode centrale (5) et une base des électrodes latérales (2, 3).
  2. Parasurtenseur selon la revendication 1, conçu de telle sorte que la tension d'amorçage aux chocs dans le cas d'une augmentation de tension de 1 kV/µs soit inférieure à 2,2 fois la tension nominale continue d'amorçage et en ce que des paramètres prédéterminés de l'électrode centrale (5) et de l'une des électrodes latérales (2, 3) sont identiques.
  3. Parasurtenseur selon l'une des revendications précédentes, de forme cylindrique et dont le diamètre extérieur est inférieur à 8 mm.
  4. Parasurtenseur selon l'une des revendications précédentes, dans lequel les électrodes latérales (2, 3) et/ou l'électrode centrale (5) sont toutes constituées de l'assemblage de deux parties d'électrode.
  5. Parasurtenseur selon la revendication 4, dans lequel les parties d'électrode situées dans l'espace intérieur du parasurtenseur contiennent du cuivre et les parties d'électrode accessibles de l'extérieur un alliage de fer et de nickel.
  6. Parasurtenseur selon l'une des revendications précédentes, dans lequel l'électrode centrale (5) est constituée de l'assemblage d'une partie tubulaire (5b) et d'une partie annulaire (5a).
  7. Parasurtenseur selon l'une des revendications précédentes, dans lequel les parties d'électrode (2a, 3c) accessibles de l'extérieur des électrodes latérales (2, 3) sont rondes ou carrées.
  8. Parasurtenseur selon l'une des revendications précédentes, dans lequel les électrodes latérales (2, 3) prévues dans l'espace intérieur ont la forme d'une tige et s'enfoncent concentriquement par rapport à l'électrode centrale (5) dans la zone occupée par l'électrode centrale (5).
  9. Parasurtenseur selon l'une des revendications précédentes, dans lequel l'espace intérieur contient un gaz additionné d'hydrogène.
  10. Parasurtenseur selon l'une des revendications précédentes, selon la revendication 9, dans lequel les surfaces frontales des électrodes latérales (2, 3) présentent un gaufrage (8).
  11. Parasurtenseur selon l'une des revendications précédentes, dans lequel des lignes d'allumage (6) sont prévues dans l'espace intérieur et sont plus courtes que l'électrode latérale (2, 3) concernée lors d'un contact avec l'une des électrodes latérales (2, 3).
  12. Utilisation d'un parasurtenseur selon l'une des revendications précédentes dans un appareil électronique ou dans un réseau électrique.
