摘要
随着数据业务爆发式增长,UPS的使用量大大增加,造成了机房面积占用较大、投资较高等问题。文章介绍了以直流供电代替交流UPS供电的驱动力,阐述了高压直流供电系统的基本原理,并讨论了国内主推的240V和336V高压直流供电系统,论证了高压直流供电技术的供电可靠性、节能性、安全性及可行性,总结了我国高压直流供电的发展策略。
With the explosive growth of data services, use of UPS increases greatly resulting in more machine room ar- ea needed, higher investment and other issues. This article introduces the impetus of substituting UPS with HVDC power supply. Firstly, the fundamental principles of HVD2 power supply is illustrated. Then, the 240 V and 336 V systems mainly applied in China are discussed. Features such as reliability, energy saving advantage, safety and feasibility of HVIC are demonstrated and following that is development strategy of HVDC Dower supply in China.
