DC600V Power Supply System Solution for Passenger Train
解决方案介绍 Solution introduction：
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.
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.
方案应用 Solution application：
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.
