Positive safety system with control relay and current regulation functions
Description
The positive safety system described, with controlled relay and current regulation functions, is particularly used for controlling the safety absorbers of a nuclear reactor. It includes an input E connected to a periodic current source having a nonzero amplitude in normal operation, a negative current feedback static amperage regulator, the input of which is connected through a galvanic isolation transformer Ta to the input E, a power supply unit A delivering a d.c. voltage, a rectifier R connected to the secondary winding of a transformer Tb delivering a constant current in a load impedance, by connection leads, one of which passes through the static amperage regulator to bring about the negative current feedback

On presente un appareil a securite positive, ayant les fonctions de relais de commande et de regulation de courant, utilise notamment pour la commande des absorbants de securite d'un reacteur nucleaire. Il comprend: une entree E reliee a une source de courant periodique, d'amplitude non nulle en marche normale, un regulateur statique d'intensite a contre-reaction de courant, dont l'entree est reliee par l'intermediaire d'un transformateur d'isolation galvanique Ta a l'entree E, une alimentation A delivrant une tension continue, un redresseur R relie au secondaire du transformateur Tb delivrant un courant constant dans une impedance de charge, par des fils de connexion dont l'un d'eux passe a travers le regulateur statique d'intensite pour realiser la contre-reaction de courantAdditional details
