解決方案介紹  Solution introduction：

DC600V電源裝置包括兩個系統(tǒng)柜：客車空調逆變電源和客車充電器；逆變電源柜將來自機車的DC600V電壓變換為三相交流380V/50Hz電源，給車廂內的空調裝置提供電力供應。充電器柜內裝DC120V充電機與AC220V單相逆變器，充電機將DC600V電壓轉換成DC120V電源為應急電池組充電，單相逆變器將DC120V電源轉換成單相AC220V/50Hz電源。

DC600V power supply device includes two system cabinets: passenger train air conditioning inverter power supply cabinet and passenger train charger cabinet; the inverter power supply cabinet converts the DC600V voltage from the train into three-phase AC 380V/50Hz power, to supply power for the air conditioning devices in carriages. The charger cabinet is installed with a DC120V battery charger and a AC220V single-phase inverter; the battery charger converts the DC600V voltage into DC120V power to charge the emergency battery pack, and the single-phase inverter converts the DC120V power into single-phase AC220V/50Hz power.  

逆變器與充電器均采用自然冷方式散熱，相較風冷產(chǎn)品，產(chǎn)品故障率可有效降低；兩種系統(tǒng)柜防護等級均達到IP54級別，密封性能良好，可適應全國各種風沙雨雪天氣；三種模塊主要單板及軟件互相兼容，產(chǎn)品維護簡單方便。

Both the inverter and charger adopt natural cooling for heat dissipation, and they have lower failure rate compared with the products adopting air cooling. The two kinds of system cabinets have IP54 protection level and good sealing property, so they can adapt to all kinds of windy, sandy, rainy and snowy weather throughout the country; there are three kinds of modules, the main single boards and software are compatible with each other and the maintenance for the products is easy and convenient.

方案應用  Solution application：

鼎漢技術DC600V電源裝置在國鐵25G/25T型旅客列車上已進行大量的應用實踐，應用范圍覆蓋全國大部分路局，裝車數(shù)量超過一千個，應用數(shù)量較多的路局有：廣州鐵路局，蘭州鐵路局，哈爾濱鐵路局，烏魯木齊鐵路局等，經(jīng)過高寒、高熱、風沙雨雪等各種惡劣工況的考驗，產(chǎn)品運行狀況良好，質量穩(wěn)定。

The Dinghan DC600V power supply device has been carried out a large number of application practices on National Railway 25G/25T passenger trains; the quantity of the power supply devices that have been installed on trains has exceeded one thousand; their application scope covers most of railway bureaus in the country; thereinto, they are widely used in the railway bureaus such as Guangzhou Railway Bureau, Lanzhou Railway Bureau, Haerbin Railway Bureau and Urumchi Railway Bureau adopt larger numbers of the power supply devices; although these devices experienced various severe operating conditions, they are always operating in good condition with stable quality.
