Abstract
(EN)
The present invention relates to a DC circuit breaker that, when failure occurs on a direct current (DC) line, can interrupt, bidirectionally from a mechanical switch, the fault current flowing on the DC line. The DC circuit breaker, according to the present invention, comprises: a mechanical switch installed on a DC line and opened when failure occurs on one side or the other side of the DC line so as to interrupt a current on the DC line; a first bidirectional switching element connected in parallel to the mechanical switch for switching the bidirectional current flow; an LC circuit connected in parallel to the mechanical switch and comprising a capacitor and reactor connected to each other in series for generating an LC resonance; a first unidirectional switching element connected in parallel to the LC circuit for switching the current flow so as to generate the LC resonance; and a second bidirectional switching element connected in series to the LC circuit for switching the bidirectional current flow.

La présente invention concerne un coupe-circuit c.c. qui, lorsqu'un défaut se produit sur une ligne de courant continu (c.c.), peut couper de manière bidirectionnelle, grâce à un commutateur mécanique, le courant de défaut circulant sur la ligne c.c. Le coupe-circuit c.c. selon cette invention comprend : un commutateur mécanique installé sur une ligne c.c., qui est ouvert lorsqu'un défaut se produit sur l'un ou l'autre côté de la ligne c.c., de façon à couper le courant sur la ligne c.c. ; un premier élément de commutation bidirectionnelle monté en parallèle avec le commutateur mécanique pour inverser le flux de courant bidirectionnel ; un circuit LC monté en parallèle avec le commutateur mécanique et comportant un condensateur et une bobine de réactance montés en série pour générer une résonance LC ; un premier élément de commutation unidirectionnelle monté en parallèle avec le circuit LC afin d'inverser le flux de courant de manière à générer la résonance LC ; et un second élément de commutation bidirectionnelle monté en série avec le circuit LC pour inverser le flux de courant bidirectionnel.
