Title
(DE) LASTSTUFENSCHALTER
(EN) ON-LOAD TAP CHANGER
(FR) COMMUTATEUR EN CHARGE À GRADINS
Abstract
(DE)
Die vorliegende Erfindung betrifft einen Laststufenschalter zur unterbrechungslosen Umschaltung zwischen verschiedenen Wicklungsanzapfungen eines Stufentransformators gemäß dem Oberbegriff des ersten Patentanspruches. Die allgemeine erfinderische Idee besteht darin, den Laststufenschalter mittels eines Getriebemoduls an der Unterseite des Transformatordeckels anzuordnen.
(EN)
The present invention relates to an on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer according to the first claim. The general inventive concept is that of arranging the on-load tap changer on the underside of the transformer cover by means of a gear module.
(FR)
La présente invention concerne un commutateur en charge à gradins servant à commuter sans interruption différentes prises du bobinage d'un transformateur à prises selon le préambule de la première revendication. Le concept inventif de base consiste à monter le commutateur en charge à gradins relié à un module réducteur sur le dessous du couvercle du transformateur.
