초록

회로차단기에서 가장 중요한 성능은 전기시스템의 이상전류를 신속하게 차단하는 것이다. 이러한 차단시간은 조작기구의 동적 특성에 의한 영향을 받는다. 따라서 회로차단기의 차단시간 단축을 위해서는 조작기구의 최적화가 이루어져야 한다. 본 논문의 가스회로차단기의 조작기는 스프링으로 구동되며 여러 개의 Latch 로 구성되어있다. Latch 들의 상대적 위치와 길이로 정의된 각 설계변수의 차단시간에 대한 영향을 분석하고 이 결과를 통해 설계변수를 선정하여 ADAMS 와 VisualDOC 의 연동을 통해 최적화를 수행하였다. Latch 들의 최적화를 통해 약 22.5% 개극시간을 향상을 확인하였다.

Breaking time is an important performance indicator of a circuit breaker. Thus, the operating mechanism of the circuit breaker should be optimized for reducing the breaking time. The operating mechanism in a gas circuit breaker is made up of several latches. Specifically, the geometry and relative positions of latches influence the dynamic behaviors of the operating mechanism. In this study, a three-stage latch operating mechanism is analyzed on the basis of the verified multibody dynamics model constructed using the MSC.ADAMS program. The relative positions and lengths of latches are selected as design variables. The dominant design variables are selected by a design study. Optimization is performed using a genetic algorithm (GA). The study results demonstrate that the performance of the circuit breaker improves by about 22.5.
