摘要
随着移动通信的发展,远端设备的供电问题亟需解决。对射频单元(RRU)及远端设备的三种供电方案:市电直接供电、市电+不间断电源(UPS)供电、直流远程供电系统进行了对比。直流远程供电系统可降低管理及运维成本,并可减少意外停电造成的损失。通过工程实例证明,远程供电系统的供电方式完全满足现行形势下通信设备的各种运用场景,值得运用与推广。
With the development of mobile communication, remote equipment of the power supply problem need to be solved. Three kinds of power supply scheme of RRU and the remote equipment, such as mains powered directly, mains ＋ UPS power supply, DC remote power supply system were compared. DC remote power supply system could reduce the cost of management and operations, and reduce the loss caused by unexpected power outages. And through the engineering example, it proved that the remote power supply system of power supply can completely satisfy the various use of the current situation of communications equipment scene, it is worth applying and popularizing.
