Abstract

Automatic circuit reclosers protect electrical distribution systems by breaking the circuit should the current levels exceed an acceptable range. In the process of opening and closing the circuit, welds are formed between the contacts, making it difficult to separate the contacts again. In order to ensure that the contacts can be separated in the event of a fault, a mechanism has been constructed to impart an impact load on the weld. This mechanism has been designed and used for many years with little understanding of how the mechanism components affect the performance of the mechanism. In order to gain this understanding, a dynamic model of the mechanism was created.
