(FR) COMPOSANT ÉLECTRIQUE PASSIF POUR SYSTÈME D’ARRÊT DE SÉCURITÉ UTILISANT LA LOI DE FARADAY
Abstract
(EN)
An electro-technical device includes a first coil connected to a first sensor for receiving a current therefrom representative of a sensed condition, the first coil being anchored at first and second ends. A second coil is connected to a second sensor for receiving a current therefrom representative of a sensed condition, the second coil being anchored at first and second ends and being adjacent to the first coil. When the first and second coils receive an increased current from the first and second sensors, the first and second coils each create a magnetic flux that repel one another in order to cause at least one of the coils to break so that a shutdown signal can be sent.

L'invention concerne un dispositif électrotechnique comprenant une première bobine connectée à un premier capteur pour recevoir un courant provenant de celui-ci représentatif d'un état détecté, la première bobine étant ancrée à des première et seconde extrémités. Une seconde bobine est connectée à un second capteur pour recevoir un courant provenant de celui-ci représentatif d'un état détecté, la seconde bobine étant ancrée à des première et seconde extrémités et étant adjacente à la première bobine. Lorsque les première et seconde bobines reçoivent un courant accru provenant des premier et second capteurs, les première et seconde bobines créent chacune un flux magnétique, lesdits flux magnétiques se repoussent mutuellement afin de provoquer la rupture d'au moins une des bobines de telle sorte qu'un signal d'arrêt peut être envoyé.
