解決方案介紹  Solution introduction：

城軌電源產(chǎn)品系統(tǒng)解決方案，包含了輔助變流器（逆變器+蓄電池充電機(jī)）、空調(diào)專用變頻器、緊急通風(fēng)逆變器、空調(diào)逆變器、蓄電池充電機(jī)等產(chǎn)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）輔助變流器將接觸網(wǎng)或第三軌的1500VDC的高壓直流電轉(zhuǎn)換為AC380V三相交流電，給列車上的風(fēng)扇、空調(diào)單元、空氣壓縮機(jī)等三相負(fù)載等交流負(fù)載供電；同時產(chǎn)生DC110V的直流電壓，給列車上的直流負(fù)載供電和給蓄電池充電。

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）空調(diào)專用變頻器將列車上的AC380V交流電轉(zhuǎn)換成電壓頻率可調(diào)的三相交流電，主要用于地鐵變頻空調(diào)供電。

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）緊急通風(fēng)逆變器在地鐵主回路供電出現(xiàn)故障時，將車載蓄電池的110V直流電逆變成AC380V三相交流電，給地鐵空調(diào)緊急供電，保證地鐵內(nèi)部車廂的通風(fēng)。

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）空調(diào)逆變器將接觸網(wǎng)或第三軌的1500VDC的高壓直流電轉(zhuǎn)換為AC380V三相交流電，給列車上的通風(fēng)機(jī)、空氣壓縮機(jī)等三相負(fù)載等交流負(fù)載供電。

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）蓄電池充電機(jī)將將接觸網(wǎng)或第三軌的1500VDC的高壓直流電或交流母線的三相AC380V轉(zhuǎn)換為DC110V的直流電壓，給列車上的直流負(fù)載供電和給蓄電池充電。

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.
