Abstract

Circuit de protection de thyristors montés en série contre l'auto-amorçage. A chaque thyristor est associé un dispositif qui, en cas de tension negative aux bornes du thyristor, délivre un signal de commutation transmis à un dispositif d'évaluation M qui forme un signal temporisé correspondant au temps de récupération de la valve considérée et qui est transmis avec le signal d'amorçage à un circuit logique tandis qu'un second circuit de surveillance produit un second signal de commutation en cas de tension positive aux bornes du thyristor, le circuit logique commandant le circuit d'amorçage lorsque ce second signal apparaît déjà pendant l'apparition du signal temporisé.
