Abstract

Die Erfindung bezieht sich auf einen Sprungfederantrieb (1) für das bewegliche Schaltstück eines elektrischen Erdungs- oder Trennschalters, das über Hebel mit der Antriebswelle (2) verbunden ist, der einen starr mit der Antriebswelle (2) verbundenen Antriebshebel (4) sowie einen Betätigungshebel (8) enthält und bei dem die als Druckfeder ausgebildete Sprungfeder (6) an beiden Enden gelenkig gelagert ist, wobei das eine Ende mit einem drehbar auf der Antriebswelle (2) angeordneten Spannhebel (3) verbunden ist. The invention relates to a spring drive (1) for the moving contact of an electrical Earthing or disconnect switch, which is operated by lever with the Drive shaft (2) is connected, which is rigid with the Drive shaft (2) connected drive lever (4) and contains an operating lever (8) and in which the as Spring formed compression spring (6) at both ends is articulated, one end rotatable with one tension levers (3) arranged on the drive shaft (2) connected is.

Um den Antriebshebel (4) während des Spannens der Sprungfeder (6) in Ruhelage zu halten, ist das andere Ende der Sprungfeder (6) mit der von der Antriebswelle (2) abgewandten Seite (5) des Antriebshebels verbunden und der Betätigungshebel (8) greift am Spannhebel (3) an. Die Kraft der durch Bewegung des Spannhebels (3) sich langsam spannenden Sprungfeder (6) drückt den Antriebshebel (4) bis zum Erreichen der Strecklage (10,13) in seine Endlage. Erst danach wird er durch das schlagartige Entspannen der Sprungfeder (6) in die andere Endlage gedreht und bewegt somit die Antriebswelle (2). To the drive lever (4) while tensioning the Keeping the spring (6) at rest is the other end the spring (6) with that of the drive shaft (2) connected side (5) of the drive lever and the operating lever (8) engages the tensioning lever (3). The Force slowly by moving the tensioning lever (3) exciting spring (6) pushes the drive lever (4) up to reach the extended position (10,13) in its end position. First then he is suddenly relaxed by the Spring (6) turned to the other end position and moved thus the drive shaft (2).
