Title (DE) VERFAHREN ZUR UNTERBRECHUNGSLOSEN UMSCHALTUNG ZWISCHEN WICKLUNGSANZAPFUNGEN EINES STUFENTRANSFORMATORS
(EN) METHOD FOR SWITCHING WITHOUT ANY INTERRUPTION BETWEEN WINDING TAPS ON A TAP-CHANGING TRANSFORMER
(FR) PROCÉDÉ DE COMMUTATION SANS INTERRUPTION ENTRE DES PRISES DE BOBINAGE D'UN TRANSFORMATEUR À GRADINS
Abstract: front page image
(DE)Die Erfindung betrifft ein Verfahren zur unterbrechungslosen Umschaltung zwischen zwei Wicklungsanzapfungen (tap n, tap n+1) eines Stufentransformators, wobei jede der beiden Wicklungsanzapfungen über jeweils einen mechanischen Schalter (Ds) und eine in Reihe dazu angeordnete Reihenschaltung aus zwei entgegengesetzt geschalteten IGBT' s (Ip, In) mit der gemeinsamen Lastableitung verbunden ist.
(EN)The invention relates to a method for switching without any interruption between two winding taps (tap n, tap n+1) of a tap-changing transformer, wherein each of the two winding taps is connected to the common load output line via in each case one mechanical switch (Ds) and a series circuit, arranged in series thereto, comprising two IGBTs (Ip, In) which are switched in opposite directions.
(FR)Procédé de commutation sans interruption entre deux prises de bobinage (tap n, tap n+1) d'un transformateur à gradins, chacune des deux prises de bobinage étant connectée à la dérivation de charge commune par l'intermédiaire d'un commutateur mécanique (Ds) et d'un montage en série relié en série au commutateur et composé de deux transistors IGBT (Ip, In) montés de manière opposée.
