ABSTRACT:
Communication base station switching power supply system is the core equipment in the communication base station power supply system, which directly affects the power of the equipment and determines whether the equipment is working properly. At present in a large number of switching power supply system with inputs used for a long time, a considerable proportion of extended service. But there are many devices, large load, the difficulty of cutover construction difficult, heavy workload. Also the inevitable presence of complex fault, natural disasters and other causes switching power supply system is not working and need emergency needs of rapid cutover. Based on the actual demand, combined with the daily work experience, to explore the rapid cutover method for switch power supply。
KEY WORDS:
Communication base station, switching power supply, rapid cutover cutover, transposition, study。
1 概述
根据实际需求,结合日常工作经验,先容一种开关换位不断电开关电源割接方法,供参考和探讨。
2 开关电源系统概况
通信基站目前采用的开关电源主要为高频开关电源,一般由交流配电单元、整流模块、监控单元、直流输出单元、机架等组成,其核心是整流模块,因此平时常用开关电源或整流模块互相指代。通信用开关电源系统结构如图:
