解决方案介绍  Solution introduction:

城轨电源产品系统解决方案,包含了辅助变流器(逆变器+蓄电池充电机)、空调专用变频器、紧急通风逆变器、空调逆变器、蓄电池充电机等产品。

The solutions for urban rail power supply system involve auxiliary converter (inverter+ battery charger), dedicated frequency converter for air conditioner, emergency ventilation inverter, air-conditioning inverter, battery charger and other products. 

(1)辅助变流器将接触网或第三轨的1500VDC的高压直流电转换为AC380V三相交流电,给列车上的风扇、空调单元、空气压缩机等三相负载等交流负载供电;同时产生DC110V的直流电压,给列车上的直流负载供电和给蓄电池充电。

The auxiliary converter converts 1500VDC high-voltage direct current supplied by the overhead contact line system or third rail into AC380V three-phase alternating current to supply power for three-phase loads and AC loads such as fans, air conditioning units and air compressors on the subway, and simultaneously produces DC110V voltage to supply power for the DC loads and charge the batteries on the subway. 

(2)空调专用变频器将列车上的AC380V交流电转换成电压频率可调的三相交流电,主要用于地铁变频空调供电。

The dedicated frequency converter for air conditioner converts the AC380V alternating current on the subway into three-phase alternating current of which the voltage frequency can be adjusted to mainly supply power for the inverter air conditioners on the subway. 

(3)紧急通风逆变器在地铁主回路供电出现故障时,将车载蓄电池的110V直流电逆变成AC380V三相交流电,给地铁空调紧急供电,保证地铁内部车厢的通风。

The emergency ventilation inverter, in case of power supply failure of the main power supply circuit for the subway, converts the 110V direct current produced by the train-mounted battery into AC380V three-phase alternating current to supply emergency power for air conditioners on the subway and thus to ensure ventilation for the interior subway cars.  

(4)空调逆变器将接触网或第三轨的1500VDC的高压直流电转换为AC380V三相交流电,给列车上的通风机、空气压缩机等三相负载等交流负载供电。

The air-conditioning inverter converts the 1500VDC supplied by the overhead contact line system or third rail into AC380V three-phase alternating current to supply power for the three-phase loads and AC loads such as ventilation fans, air compressors, etc on the train. 

(5)蓄电池充电机将将接触网或第三轨的1500VDC的高压直流电或交流母线的三相AC380V转换为DC110V的直流电压,给列车上的直流负载供电和给蓄电池充电。

The battery charger converts the 1500VDC high-voltage direct current supplied by the overhead contact line system or third rail or the AC bus three-phase AC380V into DC110V direct current voltage to supply power for the DC loads and charge the batteries on the train.
