  • Each can be used as a joint per se known design are used by which is achieved that when pivoting the coupling lever an axial displacement of those carrying the second switching contact Contact rod is reached.
  • the electrical Field in the switching path controlling movement of the coaxial shielding electrode arranged to the insulating material nozzle, which is not connected to the insulating material nozzle in the case of a in the event of a switch-off movement in opposite direction of the second switching contact is achieved by at each Leg of the fork each articulated a further connecting rod is attached, which is pivotable with an axially displaceable second holder arranged on the first holder is connected, on which two push rods are arranged are connected to the shield electrode.
  • These connecting rods are in the middle of the range Leg of the fork connected to it in an articulated manner, that the path covered during a switch-off process the shielding electrode, the direction of which is always that of the first Switch contact corresponds and the amount of the speed is always less than the speed of the first switching contact, is smaller than that of the second Switching contact.

Abstract

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).
