| Zusammenfassung: | The essence of the invention of a drive mechanism for power circuit breakers is that the advantages of the previously known mechanisms of various types have been combined by means of an original construction and by the use of a simple, kinematic chain (link quadrilateral bell crank control, four-bar linkage) and a novel overrunning clutch. These advantages are: the correct design of a given function which, in the case of the previous known solutions, could be carried out only by means of a complex kinematic chain (link pentagonal bell crank control, five-bar linkage); a long life and reliability such as that which (link) mechanisms with a simple kinematic chain have. |
