Abstract
An actuating mechanism for a vacuum-type interrupter with a contact spring. The actuating mechanism of a vacuum-type interrupter has a pivotally positioned two-armed lever and a spring which holds the contact force ready and which engages with the lever. The two-armed lever is guided with limited displacement in a bearing in a direction which runs approximately parallel to the actuation direction of the interrupter. While enabling, the two-armed lever pivots about a bearing bolt around the end of the bolt guiding until the contact elements engage each other. The further pivoting of the lever takes place around a linkage assembly between the two-armed lever and the actuating impact rod. The two-armed lever can be formed from two parallel split levers with a clearance such that the spring can engage between the split levers. The actuating mechanism is suitable for one or multiple vacuum circuit breakers, e.g., for use in gas insulated switchgear. '
