Abstract

Dispositif de détection et de protection d’une installation électrique d’un aéronef contre des arcs électriques. Ce dispositif (50) comprend un capteur de courant (52.1-52.n) disposé sur chaque ligne d’alimentation (40.1-40.n) connectant en parallèle une source d’énergie électrique (20) continue haute tension et une charge électrique (30), un module de calcul (54) recevant les mesures du courant électrique de chaque capteur de courant, calculant une différence relative du courant électrique entre deux lignes d’alimentation sur la base desdites mesures reçues, comparant ladite différence relative calculée à un seuil prédéterminé, et transmettant un signal d’activation (Sact) lorsque la différence relative calculée est supérieure au seuil prédéterminé, et un module de coupure (56) configuré pour interrompre la transmission de l’énergie électrique à réception du signal d’activation. Ce dispositif permet de détecter efficacement la présence d’un arc électrique sur une des lignes d’alimentation, et donc d’éviter l’activation parasite du module coupure. Figure 2Device for detecting and protecting an aircraft electrical installation against electric arcs. This device (50) comprises a current sensor (52.1-52.n) arranged on each power line (40.1-40.n) connecting in parallel a high voltage direct electrical energy source (20) and an electrical load (30), a calculation module (54) receiving the electric current measurements from each current sensor, calculating a relative difference in the electric current between two power lines based on said received measurements, comparing said calculated relative difference to a predetermined threshold, and transmitting an activation signal (Sact) when the calculated relative difference is greater than the predetermined threshold, and a cut-off module (56) configured to interrupt the transmission of electrical energy upon receipt of the activation signal. This device makes it possible to effectively detect the presence of an electric arc on one of the power lines, and therefore to avoid parasitic activation of the cut-off module. Figure 2
