VCB 조작기의 동역학 해석 및 실험

In recent, the size of spring type circuit breaker is smaller and smaller for reducing the product costs through the technology development. In this research, for the purpose of improving the design technology, a systematic research through the experiment and computer-based dynamic analysis are carried out. RecurDyn program is employed for the multi-body dynamic analysis. The vacuum circuit breaker(VCB) is modeled as the multi-body systems and the brake shaft is considered as a flexible body for including flexible effects during operation. The simulation results show good agreements with experiments according to stem displacements and rotating angle of the brake shaft.
