Title
(EN) AC/DC CONVERTER ARRANGEMENT
(FR) AGENCEMENT DE CONVERTISSEUR ALTERNATIF/CONTINU
Abstract
(EN)
In an AC/DC converter arrangement, it is proposed that an input of an AC circuit breaker (1) forms an AC input (8) of the arrangement, an output of the AC circuit breaker (1) being connected to an input (9) of a rectifier (21), a smoothing capacitor (4) connecting a first output (10) to a second output (11) of the rectifier (21), the first output (10) of the rectifier (21) being connected to a first isolating relay (7), an output of the first isolating relay (7) forming a DC output (12) for connecting a DC network, a control and monitoring unit (15) being designed to initiate a separation of the AC input (8) from the DC output (12, 28) in a first step upon detection of a short-circuit current such that a resonant circuit consisting of the smoothing capacitor (4) and an inductance of the DC network connected to the first DC output (12, 28) is excited so as to oscillate, the first isolating relay (7) subsequently being opened.
(FR)
La présente invention concerne un agencement de convertisseur alternatif/continu CA/CC, dans lequel il est proposé qu'une entrée d'un disjoncteur CA (1) forme une entrée CA (8) de l'agencement, une sortie du disjoncteur CA (1) étant connectée à une entrée (9) d'un redresseur (21), un condensateur de lissage (4) reliant une première sortie (10) à une seconde sortie (11) du redresseur (21), la première sortie (10) du redresseur (21) étant connectée à un premier relais d'isolation (7), une sortie du premier relais d'isolation (7) formant une sortie de courant continu (12) pour connecter un réseau de courant continu, une unité de commande et de surveillance (15) étant conçue pour initier une séparation de l'entrée de courant alternatif (8) à partir de la sortie de courant continu (12, 28) dans une première étape lors de la détection d'un courant de court-circuit de telle sorte qu'un circuit résonnant constitué du condensateur de lissage (4) et d'une inductance du réseau de courant continu connectée à la première sortie de courant continu (12, 28) est excité de manière à osciller, le premier relais d'isolation (7) étant ensuite ouvert.
