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%.
