Title (DE) STUFENSCHALTER MIT HALBLEITER-SCHALTELEMENTEN
(EN) TAP SWITCH WITH SEMICONDUCTOR SWITCHING ELEMENTS
(FR) COMMUTATEUR À GRADINS POURVU D'ÉLÉMENTS DE COMMUTATION À SEMI-CONDUCTEUR
Abstract: front page image
(DE)Die Erfindung betrifft einen Stufenschalter 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. Erfindungsgemäß ist jeder IGBT durch jeweils einen dazu parallel geschalteten, besonders dimensionierten Varistor (Vp, Vn) überbrückt.
(EN)The invention relates to a tap switch for uninterrupted changeover between two winding taps (tap n, tap n+1) of a tapped transformer, wherein each of the two winding taps is connected to the common outgoing load line via in each case a mechanical switch (Ds) and a series circuit which is arranged in series therewith and which is composed of two oppositely connected IGBTs (Ip, In). According to the invention, each IGBT is bridged by in each case a specially dimensioned varistor (Vp, Vn) connected in parallel therewith.
(FR)Commutateur à gradins pour la commutation sans interruption entre deux prises de bobinage (tap n, tap n+1) d'un transformateur à gradins, chacune des deux prises de bobine 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). Selon l'invention, chaque IGBT est ponté par une varistance (Vp, Vn) montée au parallèle au transistor concerné et présentant une dimension particulière.
