A Study on the Dynamic Behavior Characteristics of the Hydraulic Electric Power Circuit Breaker

유압 전력 차단기의 동특성에 관한 연구

Hydraulic circuit breaker is the most popular type of electric power circuit breaker because of its superiority of operating performance and capacity. For the improvement of hydraulic circuit breaker's operating performance, it is very important to analyze its dynamic behavior characteristics. In this study, hydraulic circuit is modeled, analyzed and experimented. As a result, the experimental data agree well with the numerical ones, and the numerical results can be applied to the design and the improvement of hydraulic electric power circuit breaker.
