Definitions

  • the present disclosure relates to a direct-current circuit breaker including a lightning arrester.
  • a direct-current circuit breaker forms a current zero point by superimposing an oscillating current on a direct current, and interrupts the direct current at the current zero point.
  • a direct-current circuit breaker of a forced-extinction type which includes a resonance circuit including a capacitor and a reactor and performs extinction by superimposing a resonance current generated by discharge of the capacitor on a direct current.
  • Patent Literature 1 discloses a direct-current circuit breaker including a lightning arrester for suppressing an overvoltage of a capacitor when interrupting a direct current.
  • Patent Literature 2 relates to a DC circuit breaker, provided with: a main circuit breaker inserted into a DC wire, a resonance circuit connected in parallel to the main circuit breaker, and a MOSA connected in parallel to the main circuit breaker through the resonance circuit; and a main circuit breaker inserted into a DC wire, a switch serially connected to the main circuit breaker, a resonance circuit connected in parallel to the main circuit breaker, and a MOSA connected in parallel to the main circuit breaker through the resonance circuit.
  • the DC wire is a wire branching from the DC wire and returning to the DC wire.
  • the switch is inserted on the upstream side of the DC wire.
  • Patent Literature 3 relates to a lightning arrester.
  • Non-Patent Literature 1 relates to a realization of heavy-duty zinc-oxide type lightning arrestors by parallel connection.

Claims (7)

  1. Disjoncteur à courant continu (1) comportant un disjoncteur (3) adapté pour interrompre un courant continu circulant dans une ligne à courant continu (2), le disjoncteur à courant continu (1) comprenant :
    un circuit résonnant comportant un condensateur (4), un réacteur (5) et un commutateur (6) connectés en série les uns aux autres ;
    un parafoudre (7) ; et
    un processeur d'opération (11) adapté pour commander une opération d'ouverture et une opération de fermeture par chacun parmi le disjoncteur (3) et le commutateur (6),
    caractérisé en ce que le parafoudre (7) comporte une pluralité de colonnes (20) comportant chacune une pile d'une pluralité d'éléments résistants non linéaires (24), le parafoudre (7) étant connecté en parallèle au condensateur (4),
    dans lequel le disjoncteur à courant continu (1) comprend en outre :
    un élément de surveillance (12) adapté pour surveiller la présence ou l'absence d'une anomalie dans chaque colonne parmi la pluralité de colonnes (20) ; et
    un processeur de verrouillage (13) adapté pour :
    verrouiller des opérations du disjoncteur (3) et du commutateur (6) commandées par le processeur d'opération (11) dans un cas où il y a une anomalie dans au moins une ou plusieurs colonnes (20a) parmi la pluralité de colonnes (20) ; et
    déverrouiller les opérations du disjoncteur (3) et du commutateur (6) après la résolution de l'anomalie.
  2. Disjoncteur à courant continu (1) selon la revendication 1, dans lequel l'élément de surveillance (12) est adapté pour surveiller la présence ou l'absence d'une anomalie dans chaque colonne parmi la pluralité de colonnes (20) sur la base d'un résultat de détection d'une température de chaque colonne parmi la pluralité de colonnes (20).
  3. Disjoncteur à courant continu (1) selon la revendication 2, dans lequel l'élément de surveillance (12) est adapté pour déterminer qu'une anomalie s'est produite dans une ou plusieurs colonnes (20a) ayant une augmentation de température dépassant une température admissible parmi la pluralité de colonnes (20).
  4. Disjoncteur à courant continu (1) selon la revendication 3, comprenant un séparateur (15) adapté pour séparer la ou les colonnes (20a) dans lesquelles l'anomalie s'est produite des colonnes autres que la ou les colonnes (20a) parmi la pluralité de colonnes (20).
  5. Disjoncteur à courant continu (1) selon la revendication 4, dans lequel le processeur de verrouillage (13) est adapté pour déverrouiller des opérations du disjoncteur (3) et du commutateur (6) dans un cas où une température de chaque colonne (20) autre que la ou les colonnes (20) séparées de la pluralité de colonnes (20) a diminué jusqu'à une température de référence fixée à l'avance comme référence pour un redémarrage d'une opération.
  6. Disjoncteur à courant continu (1) selon la revendication 2, dans lequel l'élément de surveillance (12) est adapté pour déterminer qu'il y a une anomalie dans l'ensemble de la pluralité de colonnes (20) dans un cas où une température globale de la pluralité de colonnes (20) a augmenté jusqu'à une première température de référence fixée à l'avance comme référence pour une interruption d'une opération.
  7. Disjoncteur à courant continu (1) selon la revendication 6, dans lequel le processeur de verrouillage (13) est adapté pour déverrouiller des opérations du disjoncteur (3) et du commutateur (6) dans un cas où une température de chaque colonne parmi la pluralité de colonnes (20) a diminué jusqu'à une seconde température de référence fixée à l'avance comme référence pour un redémarrage d'une opération.
