摘要
针对-48V直流供电系统中存在的输电问题,文章提出了一个解决思路,即在传统直流供电系统上增加直流升/降压系统,提高输电电压,降低回路压降。该方法能减少电缆的使用,降低铜耗、节约能源。
Aiming at the-48V DC power system transmission problems that exist in telecom station,this paper gives a solution that adding DC step-up and the step-down system on the traditional DC power supply system,which can improve the transmission voltage,reduce the circuit pressure drop,the consumption of cable,copper and conserves energy.
