摘要
广州地铁1号线辅助系统低压电源将1500V直流电逆变、整流后变为110V直流提供给列车控制系统,并对列车备用蓄电池组进行浮充电。分析了低压电源控制系统的主要功能和工作原理,给出了国产化方案。通过技术性能测试及3年的运用考核,证明国产化系统完全满足运用要求。
After inversion and rectification by auxiliary system in Guangzhou Metro Line 1, 1500 V DC is changed to 110 V DC supplying to train control system and floatingly charging to train standby batteries. The main functions and work principles of low-voltage power control system are analyzed, and the localization scheme is presented. Based on the technical performance tests as well as the examination and validation for 3 years, it is testified that the localization system fully fulfills the application requireme...
