摘要
描述了万能式断路器动触头回弹的原因。对动触头防回弹结构进行优化设计及仿真分析,并使用高速摄影对设计优化结果进行验证,最终改善了动触头的回弹,加快了分闸时间,提高了产品的分断性能。
This paper described the cause of air circuit breaker contact rebound,and did the moving contact anti rebound structure optimization design and simulation analysis.By the use of high speed photography,the design optimization results were verified.Ultimately it improves the resilience of the moving contact,speeds up the opening time,improves the products breaking performance.
