Title (EN) BRIDGE-TYPE CIRCUIT, AND DIRECT CURRENT BREAKING DEVICE AND CONTROL METHOD THEREOF
(FR) CIRCUIT DE TYPE PONT, DISPOSITIF DE COUPURE DE COURANT CONTINU ET PROCÉDÉ DE COMMANDE ASSOCIÉ
(ZH) 一种桥式电路、直流电流分断装置及其控制方法
Abstract:
(EN) A bridge-type circuit comprises a H-bridge switch module and a buffering and reclosing module. The H-bridge switch module comprises four power semiconductor switch devices (Q1, Q2, Q3, Q4). Every two of the four power semiconductor switch devices are connected in series in the same direction to form a bridge arm, and the two bridge arms are further connected in parallel. Middle points of the two bridge arms respectively serve as an input terminal and an output terminal. The buffering and reclosing module is connected in parallel with the two bridge arms of the full bridge module. Also provided are a direct current breaking device formed by connecting the above bridge-type circuits in cascade and a control method thereof. The direct current breaking device is provided with the buffering and reclosing module, such that line voltage fluctuation generated during a reclosing operation is small.
(FR) L'invention concerne un circuit de type pont comprenant un module de commutation à pont en H et un module de mise en tampon et de réenclenchement. Le module de commutation à pont en H comprend quatre dispositifs de commutation à semi-conducteurs de puissance (Q1, Q2, Q3, Q4). Les deux paires de dispositifs des quatre dispositifs de commutation à semi-conducteurs de puissance sont connectées en série dans la même direction de façon à former deux branches de pont, et lesdites branches de pont sont en outre connectées en parallèle. Les points centraux des deux branches de pont servent respectivement de borne d'entrée et de borne de sortie. Le module de mise en tampon et de réenclenchement est connecté en parallèle aux deux branches de pont du module en pont complet. L'invention concerne également un dispositif de coupure de courant continu formé par connexion en cascade des circuits de type pont précités, et un procédé de commande associé. Le dispositif de coupure de courant continu est pourvu du module de mise en mémoire tampon et de réenclenchement, de sorte que la fluctuation de tension de ligne générée pendant une opération de réenclenchement soit faible.
(ZH) 一种桥式电路,包括H桥开关模块和缓冲及重合闸模块。H桥开关模块包括四个功率半导体开关器件(Q1,Q2,Q3,Q4),每两个功率半导体开关器件同向串联构成一个桥臂,两个桥臂并联连接,且两个桥臂中点分别作为输入端和输出端;缓冲及重合闸模块与全桥模块的两个桥臂相互并联。还涉及一种由前述桥式电路级联而成的直流电流分断装置及其控制方法。直流分断装置引入缓冲及重合闸模块后,重合闸操作产生的线路电压振荡小。
