Definitions

  • the reason for this behavior is that the dielectric strength in vacuum is approximately proportional to the root of the length of the insulating vacuum path. Therefore, the dielectric strength (insulation capacity) of a vacuum section increases with decreasing length of this vacuum section only disproportionately, degressively. Therefore, it is advantageous to electrically connect two or more (shorter) vacuum isolation sections in series; This makes it possible to realize a higher dielectric strength than with a single vacuum insulation section of greater length.
  • FIG. 6 shows an enlarged section of the vacuum interrupter of FIG. 5.

Abstract

L'invention concerne une ampoule à vide comportant un premier élément de contact (7) disposé sur une tige de contact (5) fixe, un deuxième élément de contact (11) disposé sur une tige de contact (9) mobile dans l'axe, et un premier écran de protection (29) contre la vapeur métallique, cet écran étant en matériau électriquement conducteur et destiné à protéger des faces internes du boîtier de l'ampoule à vide contre des dépôts de vapeur métallique. L'invention est caractérisée en ce que le premier écran de protection (29) est maintenu sur une des tiges de contact (9) par rapport à laquelle il est électriquement isolé.
