摘要
针对直流输电阀冷系统中所有空气散热器风机不能挂靠在同一电源母线上的问题,提出了一种简单可靠,经济有效的多组双电源切换方案,即将两路交流电源分别拆分成多路动力电源后,各选择一路电源组成多组双电源,每组双电源再通过微型断路器和交流接触器进行电源选择。使用这种装置时,即使在一组双电源出现故障不能正常供电失去一组散热风机的情况下,仍能保持空气散热器风机在额定容量下运行。
Since all the air fans in DC transmission valve cold system can not be anchored in the same casual,a simple reliable and economical efficiency solution,namely multigroup dual power switching system,was raised.With this solution,even if a group of double power broke down and a group of fans were out of action,the other fans would act regularly under specified capacity.
