摘要
针对空气直流断路器,利用2 kV/30 kA直流断流冲击试验电路,以及高速摄影仪等,对空气直流断路器的分断过程进行了研究,获得了大量的试验数据。基于相关研究工作,研制了1 800 V轨道交通用大容量空气直流断路器。
This paper focuses on the breaking technology in air DC circuit breaker. The research work was done with 2 kV /30 kA DC test circuit and high-speed photography. A lot of testing data were obtained. Based on these research work,a type of 1 800 V high-capacity air DC circuit breaker for rail transit was developed.
