Title
(DE) LASTSTUFENSCHALTER MIT KRAFTSPEICHER
(EN) ON-LOAD TAP CHANGER WITH ENERGY STORAGE MECHANISM
(FR) COMMUTATEUR DE RÉGLAGE EN CHARGE COMPORTANT UN ACCUMULATEUR D'ÉNERGIE
Abstract
(DE)
Die Erfindung betrifft einen Laststufenschalter mit einem Kraftspeicher, durch den eine Abtriebswelle sprungartig drehbar ist. Erfindungsgemäß ist neben der eigentlichen Kraftspeicherfeder bzw. den eigentlichen Kraftspeicherfedern mindestens eine weitere Feder vorgesehen, die nach Auslösung des Kraftspeichers Energie aufnimmt bzw. abgibt, wodurch eine Optimierung des Drehmomentverlaufes erfolgen kann.
(EN)
The invention relates to an on-load tap changer having an energy storage device, by means of which an output shaft is rotatable in spurts. According to the invention, in addition to the actual energy storage spring or the actual energy storage springs, at least one further spring is provided, which absorbs/releases energy after the activation of the energy storage mechanism, whereby the torque curve can be optimised.
(FR)
L'invention a pour objet un commutateur de réglage en charge comportant un accumulateur d'énergie grâce auquel un arbre entraîné peut être mis en rotation par à-coups. Selon l'invention, outre le ressort accumulateur d'énergie ou les ressorts accumulateurs d'énergie proprement dits, un ressort supplémentaire absorbe ou délivre l'énergie après le déclenchement de l'accumulateur d'énergie, ce qui permet de réaliser une optimisation de la courbe de couple.
