(FR) DISPOSITIF FILTRANT ET CONTRÔLEUR DE MATÉRIEL ROULANT FERROVIAIRE
Abstract
(EN) A filter device 5 that removes a noise current generated by an inverter 6 includes a first filter capacitor 52a that is provided in parallel to a direct-current unit of the inverter 6, a first filter reactor 51a that is provided between a high-potential side of the first filter capacitor 52a and an overhead line 1 that is a power supply source of direct-current power, and a series circuit unit 56 in which a fuse 53 serving as a circuit disconnecting unit that is disconnected when a current larger than a rated current flows therein, a second filter reactor 51b serving as an inductance element, and a second filter capacitor 52b serving as a capacitance element are connected in series, where one end of the series circuit unit 56 is connected to a low-potential side of the first filter capacitor 52a and one end of the first filter reactor 51a is connected to the series circuit unit 56.
(FR) Cette invention concerne un dispositif filtrant (5) conçu pour éliminer un courant de bruit généré par un onduleur (6), comprenant : un premier condensateur de filtrage (52a) monté en dérivation à une unité à courant continu (CC) de l'onduleur (6); un premier réacteur de filtrage (51a) disposé entre un côté à haut potentiel du premier condensateur de filtrage (52a) et une ligne aérienne (1) qui est la source d'alimentation en CC; et une unité de circuit série (56) pour connecter en série un fusible (53) en tant qu'unité de coupure de circuit qui se bloque au passage d'un courant supérieur à un courant de consigne, un second réacteur de filtrage (51b) qui est un élément d'inductance, et un second condensateur de filtrage (52b) qui est un élément de capacité. Une extrémité de l'unité de circuit série (56) est reliée à un côté de bas potentiel du premier condensateur de filtrage (52a) et une extrémité du premier réacteur de filtrage (51a) est reliée à l'unité de circuit série (56).
