Research on hybrid automatic transfer switching based on IGBT

对目前国内外自动转换开关的发展情况以及性能进行了分析和比较,在深入研究新型混合式断路器的基础上,阐述了一种基于IGBT混合式自动转换开关(HATS)的结构和工作原理,重点研究了该HATS的本体开关部分的合闸、分闸及限压特性,针对其动作特性,搭建实验平台模拟了该HATS的并联切换和串联切换方式,并具体分析和比较了2种不同切换方式的性能,实验结果表明:该HATS在保持机械转换开关静态特性的同时,其合闸和分闸动作的快速性、一致性及动作时的限压性能均得到改善。

The development and performance of current ATS （Automatic Transfer Switching） are analyzed. With the deep study of the new hybrid circuit breaker,the structure and working principle of HATS （Hybrid Automatic Transfer Switching） equipment based on IGBT are introduced, emphasizing on action characteristics of the noumenal switching part,such as switching on/off and voltagelimitation. Both shunt and serial switching modes of HATS are simulated and their performances are compared. Experimental results show that, HATS equipment improves its switching speed and consistency and the voltage-limitation performance,while its static characteristics of mechanical transfer switching are kept.
