Abstract

A high voltage circuit breaker was mainly used to prevent accidents that may occur during transmission and distribution. The specifications of circuit breaker and energy of mechanism were decided by voltage and current level. It is important to satisfy electric and mechanical performance of circuit breaker. In mechanical performance, the reliability of circuit breaker is related to the IEC 62271-102 standards. The mechanical endurance of interrupter is M2 class and the number of operating cycles is 10,000. In past, the repeated tests were performed to satisfy the reliability of circuit breaker, so the time and cost were very high. To reduce the time and cost, there were many studies that predict the dynamic behavior and reliability of circuit breaker. In this study, the dynamic loads were measured to analyze 550kV circuit breaker. The multibody dynamic analysis models were developed by using RecurDyn program. And the simulation results were validated with experimental results. The fatigue analysis and evaluation were executed by using simulation and experimental results.
