本文针对真空断路器的单线供电、双线供电的电路结构进行详细介绍,通过对真空断路器的内部逻辑及主断环的控制逻辑进行对比分析,得出双线供电电路结构可以提高真空断路器的可靠性,为真空断路器的进一步改善研究提供思路,为轨道交通行业中真空断路器的选型提出建议方案。

This paper gives a detailed introduction to the single-line power supply and two-wire power supply structure of vacuum circuit breaker. By comparing and analyzing the internal control logic of the vacuum circuit breaker and the control logic of the main break loop, it is concluded that the two-wire power supply circuit structure can improve the reliability of the vacuum circuit breaker. It provides ideas for further improvement of vacuum circuit breakers, and provides solutions for the selection of vacuum circuit breakers in the rail transit industry.
