Abstract
(DE)
Die Erfindung betrifft eine Kontaktanordnung für strombegrenzende Schutzschalter im Niederspannungsbereich, insbesondere für strombegrenzende Leistungsschalter. Das zu lösende Problem besteht in einen günstigeren Verlauf der Kontaktkraft über den durch den Kontaktverschleiss auftretenden Durchhub einer Kontaktanordnung (2), bei der eine Drehkontaktbrücke (10) in einer Schaltwelle (6) durch Kontaktkraftfedern (24) mit fiktiver Drehachse aufgehängt ist, wobei die ersten Enden der Kontaktkraftfedern (24) mit in Aussparungen (20) der Schaltwelle (6) gelagerten und gegen Steuerkurven (32) der Kontaktbrücke (10) drückende Gleitelemente (22) verbunden sind. Die zweiten Enden (30) der Kontaktkraftfedern (24) sind unverschieblich an der Schaltwelle (6) gelagert und die Gleitelemente (22) in ständiger Anlage mit den Steuerkurven (32).
(EN)
The invention relates to a contact arrangement for current-limiting protective circuit breakers for use in the low voltage range, especially for current-limiting power circuit breakers. The aim of the invention is to achieve a more favorable progression of the contact force over the overtravel, said overtravel occurring due to the wear of the contact, of a contact arrangement (2) in which a rotary contact bridge (10) is suspended with a fictitious rotational axis inside an actuating shaft (6) by means of contact force springs (24). The first ends of the contact force springs (24) are connected to sliding elements (22), which are mounted inside recesses (20) of the actuating shaft (6) and which press against control cams (32) of the contract bridge (10). The second ends (30) of the contact force springs (24) are mounted on the actuating shaft (6) in a non-displaceable manner, and the sliding elements (22) are in constant contact with the control cams (32).

Dispositif de contact pour disjoncteurs de protection limiteurs de courant dans la plage des basses tensions, en particulier pour sectionneurs de puissance limiteurs de courant. L'objet de la présente invention est d'obtenir une meilleure progression de la force de contact sur la course excessive d'un dispositif de contact (2) se produisant en raison de l'usure des contacts. Dans le dispositif de contact selon la présente invention, un pont de contact rotatif (10) est suspendu dans un arbre de commutation (6) par des ressorts (24) à force de contact ayant un axe de rotation fictif. Les premières extrémités des ressorts (24) à force de contact sont connectés à des éléments coulissants (22) placés dans des évidements (20) de l'arbre de commutation (6) et poussant contre des cames de commande (32) du pont de contact (10). Les secondes extrémités (30) des ressorts (24) à force de contact sont montées à demeure sur l'arbre de commutation (6) et les éléments coulissants (22) se trouvent en contact constant avec les cames de commande (32).
