解決方案介紹  Solution introduction：

DC600V電源裝置包括兩個(gè)系統(tǒng)柜：客車(chē)空調(diào)逆變電源和客車(chē)充電器；逆變電源柜將來(lái)自機(jī)車(chē)的DC600V電壓變換為三相交流380V/50Hz電源，給車(chē)廂內(nèi)的空調(diào)裝置提供電力供應(yīng)。充電器柜內(nèi)裝DC120V充電機(jī)與AC220V單相逆變器，充電機(jī)將DC600V電壓轉(zhuǎn)換成DC120V電源為應(yīng)急電池組充電，單相逆變器將DC120V電源轉(zhuǎn)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(fēng)冷產(chǎn)品，產(chǎn)品故障率可有效降低；兩種系統(tǒng)柜防護(hù)等級(jí)均達(dá)到IP54級(jí)別，密封性能良好，可適應(yīng)全國(guó)各種風(fēng)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(hù)簡(jiǎn)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(yīng)用  Solution application：

鼎漢技術(shù)DC600V電源裝置在國(guó)鐵25G/25T型旅客列車(chē)上已進(jìn)行大量的應(yīng)用實(shí)踐，應(yīng)用范圍覆蓋全國(guó)大部分路局，裝車(chē)數(shù)量超過(guò)一千個(gè)，應(yīng)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(guò)高寒、高熱、風(fēng)沙雨雪等各種惡劣工況的考驗(yàn)，產(chǎn)品運(yùn)行狀況良好，質(zhì)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.
