摘要:

针对DC 1 000 V船用大容量两断口直流断路器的设计,通过增加触头开距、引入带产气功能的窄缝灭弧技术及磁吹技术等,对大容量两断口直流断路器进行改进与优化,并进行试验验证。结果表明,改进优化的大容量两断口直流断路器样机能够有效解决40 kA短路分断和临界负载电流分断燃弧时间较长的问题,而且能够应对在高电压与大电流应用场合中,采用多极并联再串联技术所导致的大容量直流断路器体积庞大、功耗高、接线复杂等工程实际应用问题。

Abstract:

For the design of the DC 1 000 V marine high capacity two-break DC circuit breaker, the high capacity two-break DC circuit breaker is improved and optimized by increasing the contact gap, introducing the narrow-gap arc extinguishing technology with gas production function, and the magnetic blowing technology, and the experimental verification is conducted. The results show that the improved and optimized prototype of the high capacity two-break DC circuit breaker can not only effectively solve the problems of long arcing time during 40 kA short circuit breaking and critical load current breaking, but also address the practical engineering issues of large volume, high power consumption, and complex wiring caused by the use of multi-pole parallel and series technology in high voltage and large current applications.

Key words: marine, high capacity DC circuit breaker, two-break, critical load current, short-circuit current, arcing time
