电力系统通信的不中断供电电源

The uninterrupted power supplying system for electric power telecommunication

通过对电力系统通信电源的特点、现状和问题的分析,提出了采用"交流单母线分段"和"直流双母线分段"的接线方式、按"(N-1)的稳定规则"配置系统的功能单元、以"(1+1)双回路"对通信设备供电的方案,并介绍了电力系统通信不中断供电电源成套设备的原理、元器件选择、组屏及组屏工艺。

This paper analyses the characters and current situation of the power supplying system for electric power telecommunication and discusses the problem existing in the power supplying system.Then puts forward the power supplying and distributing scheme of 'AC unigeneratrix subsection' and 'DC bigeneratrix subsection'.Under the reliability rule of 'N-1'and '(1+1) protection power supplying method',this paper discusses how to configure the power supplying system for electric power telecommunication.This paper also introduces the principle,the selection of parts,configuration and technology of the uninterrupted power supplying system for electric power telecommunication.
