Abstract
(DE)
Bei einem Hochspannungsleistungsschalter mit zwei einander gegenüberstehenden Schaltkontakten (1, 2), die im Einschaltzustand von einer Isolierstoffdüse (5) umgeben sind, zu der koaxial eine Abschirmelektrode (6) angeordnet ist, wobei ein erster antreibbarer Schaltkontakt (1) über die Isolierstoffdüse (5) und ein Gestänge mit dem zweiten Schaltkontakt (2) derart in Verbindung steht, dass dieser bei Betätigung des ersten Schaltkontaktes (1) eine zu diesem gegenläufige Bewegung ausführt, steht die Abschirmelektrode (6) mit dem zweiten Schaltkontakt (2) derart in Wirkverbindung, daß sie bei einem Ausschaltvorgang eine das elektrische Feld in der Schaltstrecke (20) steuernde Bewegung ausführt.
(EN)
The invention relates to a high voltage circuit breaker, especially a gas-blast circuit breaker. Said high voltage circuit breaker has two switching contacts (1, 2) which face each other and which are surrounded by an insulating sleeve (5) when they are in their switching-on state, a screening electrode (6) being arranged coaxially in relation to said insulating sleeve. A first driveable switching contact (1) is connected to the second switching contact by the insulating sleeve (5) and a linkage mechanism, in such a way that when the first switching contact (1) is activated, said second switching contact moves in the opposite direction to the first switching contact (1). The screening electrode (6) is actively connected to the second switching contact (2) in such a way that it performs a movement controlling the electrical field in the contact gap (20) during a switching off operation.
(FR)
L'invention concerne un disjoncteur haute tension comportant deux contacts de commutation (1, 2) en vis-à-vis, qui, à l'état 'en circuit' sont entourés d'une douille en matière isolante (5), une électrode de blindage (6) étant disposée coaxialement par rapport à cette douille. Un premier contact de commutation (1) pouvant être entraîné est, par l'intermédiaire de la douille en matière isolante (5) et d'une tringlerie, en connexion avec le second contact de commutation (2), de telle sorte que ce dernier, lors de l'actionnement du premier contact de commutation (1), exécute un déplacement en sens contraire, par rapport à celui-ci, et l'électrode de blindage (6) est en liaison active avec le second contact de commutation (2) de telle sorte que, lors d'un processus de mise hors circuit, elle exécute un déplacement qui commande le champ électrique sur le trajet de commutation (20).
