Title
(DE) VAKUUMSCHALTRÖHRE
(EN) VACUUM SWITCHING TUBE
(FR) AMPOULE À VIDE
Abstract
(DE)
Die Erfindung betrifft eine Vakuumschaltröhre mit einem an einem feststehenden Kontaktbolzen (5) angeordneten ersten Kontaktstück (7), einem an einem axial beweglichen Kontaktbolzen (9) angeordneten zweiten Kontaktstück (11) und einem aus einem elektrisch leitfähigen Material bestehenden ersten Dampfschirm (29) zum Schutz von Innenflächen eines Gehäuses der Vakuumschaltröhre vor Metalldampfabscheidungen. Dabei ist der erste Dampfschirm (29) an einem der Kontaktbolzen (9) gehaltert und gegenüber diesem Kontaktbolzen (9) elektrisch isoliert.
(EN)
The invention relates to a vacuum switching tube comprising a first contact piece (7) disposed on a fixed contact bolt (5), a second contact piece (11) disposed on an axial moving contact bolt (9) and a first vapor shield (29) made of an electrically conductive material for protecting the inner surfaces of a housing of the vacuum switching tube from metal vapor depositions. The first vapor shield (29) is held at one of the contact bolts (9) and is electrically insulated against this contact bolt (9).
(FR)
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.
