Abstract[English]
An arc extinguishing device that divides the arc into multiple arcs. The process of division is achieved by initially splitting the arc into m parts as it enters the labyrinth of the large chamber, and then the weakened arc is divided into n parts as it enters the labyrinth of the smaller chambers. The total number of arc divisions equals m*n. Fig. 3 shows the step-by-step disassembly of the large chamber and the set of small chambers contained within it down to individual components. During the extinguishing process, there are no re-ignitions, voltage drops, overvoltage peaks, or emissions of ionized gases, which improves the protection conditions of the protected devices[French]
L'invention concerne un dispositif d'extinction d'arc qui divise un arc en de multiples arcs. Le processus de division est réalisé par une première division de l'arc en m parties lorsqu'il pénètre dans le labyrinthe de la grande chambre, puis l'arc affaibli est divisé en n parties lorsqu'il pénètre dans le labyrinthe des chambres plus petites. Le nombre total de divisions d'arc est égal à m*n. La figure 3 illustre le démontage étape par étape de la grande chambre et de l'ensemble des petites chambres contenues à l'intérieur, jusqu'aux composants individuels. Pendant le processus d'extinction, on ne constate aucune réinflammation, chute de tension, pic de surtension ou émission de gaz ionisés, ce qui améliore les conditions de protection des appareils protégés.
