Abstract
(EN) In relation to the supply of electric power from a storage battery to an inverter device during emergency running when a chopper device has malfunctioned, in order to resolve the problem that an excessive current flows to the storage battery when switching over a contactor that is to be connected, thereby causing the service life of the storage battery and the contactor to deteriorate, this power converting system is provided with an inverter device for driving a motor by converting direct-current power from an overhead wire into alternating-current power by way of a first opening means, a second opening means, and a first filter reactor, a chopper device for controlling the power of the storage battery by way of a third reactor, by direct current-direct current conversion of the direct-current power from the overhead wire by way of the first opening means, a third opening means, and a second filter reactor, a first contactor connected between the chopper device and the storage battery, and a second contactor connected between the first opening means and the storage battery, wherein opening and closing of the first to third opening means and the first and second contactors is controlled in accordance with malfunction detection of the chopper device and power failure detection of the overhead wire.
(FR) En relation avec l'alimentation en énergie électrique d'une batterie de stockage à un dispositif onduleur pendant un fonctionnement d'urgence lorsqu'un dispositif hacheur a mal fonctionné, afin de résoudre le problème selon lequel un courant excessif circule vers la batterie de stockage lors de la commutation sur un contacteur qui doit être connecté, ce qui provoque la détérioration de la durée de vie de la batterie de stockage et du contacteur, l'invention concerne un système de conversion de puissance comprenant un dispositif onduleur pour entraîner un moteur par conversion d'une énergie en courant continu provenant d'un fil aérien en énergie à courant alternatif par l'intermédiaire d'un premier moyen d'ouverture, d'un deuxième moyen d'ouverture et d'un premier réacteur de filtration, un dispositif hacheur pour commander l'énergie de la batterie de stockage au moyen d'un troisième réacteur, par conversion courant continu-courant continu de l'énergie en courant continu provenant du fil aérien au moyen du premier moyen d'ouverture, d'un troisième moyen d'ouverture et d'un deuxième réacteur de filtration, un premier contacteur connecté entre le dispositif hacheur et la batterie de stockage et un second contacteur connecté entre le premier moyen d'ouverture et la batterie de stockage, l'ouverture et la fermeture des premier à troisième moyens d'ouverture et des premier et second contacteurs étant commandées en fonction d'une détection de dysfonctionnement du dispositif hacheur et d'une détection d'une défaillance d'énergie du fil aérien.
(JA) チョッパ装置が故障した場合の非常走行時に、蓄電池からインバータ装置へ電力を供給するに当たり、接続する接触器の切り替え時に蓄電池に過大な電流が流れ、蓄電池や接触器の寿命を低下させるという課題を解決するために、架線から第一の開放手段、第二の開放手段および第一のフィルタリアクトルを介して直流電力を交流電力に変換してモータを駆動するインバータ装置と、架線から第一の開放手段、第三の開放手段および第二のフィルタリアクトルを介して直流電力を直流直流変換して第三のリアクトルを介して蓄電池の電力を制御するチョッパ装置と、チョッパ装置と蓄電池との間に接続した第一の接触器と、第一の開放手段と蓄電池との間に接続した第二の接触器とを備え、チョッパ装置の故障検出および架線の停電検出に応じて第一から第三の開放手段および第一並びに第二の接触器の開閉を制御する。
