通信高频开关电源双重化改造方案

The upgrading of high-frequency switching power supply system

电网的快速发展对电力通信网的可靠性、稳定性、安全性等提出了更高的要求。通信电源作为厂站通信系统的核心系统,也逐渐由以前的单母线供电方式发展成为双母线供电方式,以满足通信设备双电源输入、提高电源可靠性的需求。文章介绍了双重化双母线冷备通信电源系统的结构和特点,分析了热备通信电源系统的2种实现方案并进行了比较。

The rapid development of power grid relies on a reliable,stable and safe communication network.As one of the important parts of communication system,power supply system is changing from single bus mode to double bus mode so as to meet the requirement of dual power input and improve the reliability of power supply.This paper introduces the structure and specialties of dual power,dual bus cold standby power supply system.Two solutions for hot standby power supply system are also analysed and compared in the paper.
