摘要
介绍了中低压空气直流断路器分断系统的基本结构及工作原理,阐述了分闸特性实验的条件和流程并进行了相关试验,结合试验结果分析了断路器触头弹跳等分断过程的影响因素,为中低压直流分断性能的研究和设计,及系统安全性和稳定性的考核提供了参考和依据。
Introduction was made to the basic structure and working principle of breaking system based on mid-low voltage air DCCB. This paper expounded the experiment condition and process of separating brake characteristics and carried out the corresponding experiments. Combining with the testing result, this paper analyzed the impact factors of circuit-breaker contact bounce etc breaking process, which provides references and gists for the research and design of mid-low voltage DC breaking performance and the assess of system security and stability.
