摘要
针对地铁车站变电所电气元器件选型问题,分析了断路器操作机构和极数选型、脱扣器选型、电流互感器选型、火灾时切断非消防电源、欠压保护等。该选型分析有助于提高地铁车站低压配电系统的设计效率。
Aiming at electrical apparatus type selection for substation of metro station,the type selection for operation mechanism and pole number,release,current transformer,switching off non-fire control power supply when fire occurring,and under-voltage protection was analyzed.The analysis could help improve design efficiecy of low voltage distribution system of metrostation.
