Title (EN) CIRCUIT PROTECTION ARRANGEMENTS
(FR) CONFIGURATIONS DE PROTECTION POUR CIRCUIT
Abstract:
(EN) A circuit protection arrangement having a variable resistance sensor-interrupt element, e.g. bimetallic relay contacts, connected in series between the power supply and the load, and a control element, e.g. a series combination of a diode and a relay coil, coupled with the sensor-interrupt element. When the current in the circuit increases by a predetermined current amount, the resistance of the sensor-interrupt element increases. The control element causes the sensor-interrupt element to change from a closed state to an open state when the resistance of the sensor-interrupt element increases by a predetermined resistance amount.
(FR) Configuration de protection pour circuit à élément capteur-interrupteur et résistance de variable, par exemple sous forme de contact de relais bimétallique en série entre l'alimentation et la charge. La configuration a aussi un élément de contrôle, par exemple sous forme de combinaison en série diode et bobine de relais, l'ensemble étant relié à l'élément capteur-interrupteur. Quand le courant du circuit augmente selon une quantité prédéterminée, la résistance de l'élément capteur-interrupteur augmente. L'élément de contrôle fait passer l'élément capteur-interrupteur de l'état fermé à l'état ouvert lorsque la résistance de l'élément capteur-interrupteur augmente selon une valeur préétablie.
