Abstract
a. Dispositif pour protéger une installation électrique. b. Dispositif caractérisé en ce qu'il est prévu en supplément un moyen de protection contre les surtensions, qui comporte un commutateur susceptible d'être commandé, branché en parallèle sur la tension du générateur, ce commutateur étant susceptible d'être commuté dans l'état conducteur lorsqu'au moins une valeur de seuil d'un paramètre électrique de l'installation électrique est franchie vers le haut, tandis que la ou les diodes de Zener est ou sont sollicitées pour fonctionner en avalanche. c. L'invention s'applique notamment aux réseaux de bord des véhicules automobiles.at. Device to protect an electrical installation. b. Device characterized in that there is additionally provided a means of protection against overvoltages, which comprises a switch capable of being controlled, connected in parallel to the voltage of the generator, this switch being capable of being switched in the state conductive when at least one threshold value of an electrical parameter of the electrical installation is crossed upwards, while the Zener diode (s) is or are requested to operate in an avalanche. vs. The invention applies in particular to on-board networks of motor vehicles.
