Abstract

The dynamic characteristics of a gas circuit breaker depend on the underlying high-speed operating mechanism with a spring-actuated latch system. Many studies have been carried out to reduce the breaking time of circuit breakers. In this study, the optimum latch contour design is determined for reducing the breaking time of a circuit breaker. A multi-body dynamic model of the latch is established for analyzing the dynamic behaviors of the circuit breaker by using the MSC/ADAMS program. Simulation results are matched against experimental data. VisualDoc is employed for determining the optimal latch contour. From the optimum design, the breaking time of a gas circuit breaker is improved by about 8.6%.

가스회로차단기의 거동특성은 스프링 래치 시스템을 가진 고속 작동메커니즘에 좌우된다. 고속회로차단기의 차단시간을 줄이기 위해서 연구가 많이 이루어지고 있다. 본 연구에서는 고속회로차단기의 차단시간을 단축하기 위하여 래치의 윤곽최적설계에 관한 연구가 수행된다. 회로차단기의 거동특성을 분석하기 위해서 상용 다물체 동역학 해석프로그램인 MSC/ADAMS 를 이용하였으며, 시뮬레이션 결과는 시험을 통하여 매칭하였다. VisualDOC 를 도입하여 래치의 최적윤곽을 구하였다. 최적설계 수행결과 가스회로차단기의 차단시간을 약 8.6% 개선하였다.
