Title
(EN) TESTING METHOD FOR DC CIRCUIT BREAKER
(FR) PROCÉDÉ D'ESSAI DESTINÉ À UN DISJONCTEUR À COURANT CONTINU (CC)
(JA) 直流遮断器の試験方法
Abstract
(EN) Provided is a testing method for a DC circuit breaker, in which the circuit breaking ability of a DC circuit breaker is verified with a testing device that is used in synthetic testing for an AC circuit breaker. A testing method according to the present invention is a testing method for a DC circuit breaker 1, in which the circuit breaking ability of the DC circuit breaker 1 is verified by using a testing device including a current source circuit A and a voltage source circuit B, wherein at least an AC current from the current source circuit A is supplied to the DC circuit breaker 1, the current is shut off by the DC circuit breaker 1 when the level of the current has reached a level corresponding to a fault current due to a DC grid fault, the voltage source circuit B is connected to the DC circuit breaker 1 before the shut-off to apply a voltage to the DC circuit breaker 1, and a recovery voltage is applied from the voltage source circuit B simultaneously with the shut-off.
(FR) L'invention concerne un procédé d'essai destiné à un disjoncteur à courant continu (CC), dans lequel la capacité de rupture de circuit d'un disjoncteur CC est vérifiée avec un dispositif d'essai qui est utilisé dans l'essai synthétique d'un disjoncteur à courant alternatif (CA). Un procédé d'essai selon la présente invention est un procédé d'essai pour un disjoncteur CC (1), dans lequel la capacité de rupture de circuit du disjoncteur CC (1) est vérifiée à l'aide d'un dispositif d'essai comprenant un circuit de source de courant A et un circuit de source de tension B, au moins un courant CA délivré par le circuit de source de courant A étant fourni au disjoncteur CC (1), le courant étant coupé par le disjoncteur CC (1) lorsque le niveau du courant a atteint un niveau correspondant à un courant de défaut dû à un défaut de réseau CC, le circuit source de tension B étant connecté au disjoncteur CC (1) avant la coupure pour appliquer une tension au disjoncteur CC (1), et une tension de récupération étant appliquée par le circuit de source de tension B simultanément avec la coupure.
(JA) 交流遮断器の合成試験法に用いる試験装置で、直流遮断器の遮断性能を検証する直流遮断器の試験方法を提供する。電流源回路Aと電圧源回路Bとを備える試験装置を用いて遮断性能を検証するための直流遮断器1の試験方法であって、直流遮断器1に、少なくとも電流源回路Aから交流の電流を供給し、当該電流が直流系統の系統事故による事故電流相当となった時点で、直流遮断器1により当該電流を遮断し、前記遮断以前に、電圧源回路Bを直流遮断器1に接続することにより直流遮断器1に電圧を印加し、前記遮断と同時に電圧源回路Bから回復電圧を印加する。
