Abstract

Ce dispositif de protection (2) pour un circuit électrique (1) comprend un bloc de coupure pyrotechnique comprenant un interrupteur pyrotechnique (21) et un premier fusible (22) en parallèle avec le bloc de coupure. Le dispositif de protection comporte en outre : - un circuit de déclenchement autonome (20), comprenant : • un module de commande (24) adapté pour élaborer un signal de déclenchement et • un deuxième fusible (23), connecté en série avec le bloc de coupure et apte à fournir une tension d'alimentation au module de commande (24) pour élaborer le signal de déclenchement, - un circuit de déclenchement externe (25) pour recevoir et transmettre un signal de déclenchement vers le bloc de coupure. Les circuits de déclenchement autonome et externe sont isolés électriquement l'un de l'autre.This protection device (2) for an electric circuit (1) comprises a pyrotechnic breaking block comprising a pyrotechnic switch (21) and a first fuse (22) in parallel with the breaking block. The protection device further comprises: - an independent triggering circuit (20), comprising: • a control module (24) adapted to develop a trigger signal and • a second fuse (23) connected in series with the block switching circuit and adapted to supply a supply voltage to the control module (24) for generating the trigger signal, - an external trigger circuit (25) for receiving and transmitting a trip signal to the breaking block. The independent and external trigger circuits are electrically isolated from each other.
