摘要
在介绍固态断路器发展的基础上,总结了目前直流固态断路器的分类、结构和特点,介绍了国内外有关直流固态断路器的研究和应用动态,指出了直流固态断路器大功率化、兼具限流功能的两大发展趋势,分析了其所使用功率器件存在的均压、均流、同步控制和故障检测等技术难点和目前限流技术的种类、特点及其适用范围,并对固态断路器在直流领域的应用前景做了展望。
Based on the development of solid state circuit breaker(SSCB),this paper summarizes the sort, configuration and characteristics of DC SSCB at the present and introduces the dynamic research and application at home and broad. It points out two trends in development,which are high power and current limiting and analyzes the technological difficulties about power devices, including voltage-sharing, current-sharing, synchronization control and fault detection, which exist in application, and the type,specialty and application range of current-limiting technology. The applying prospect in DC field for SSCB is indicated.
