摘　　要：通信电源系统是通信系统的心脏,稳定可靠的通信电源供电系统,是保证通信系统安全、可靠运行的关键。一旦通信电源系统故障引起对通信设备的供电中断,通信设备就无法运行,就会造成通信电路中断、通信系统瘫痪,从而造成极大的经济和社会效益损失。因此,通信电源系统在通信系统中占据十分重要的位置。本文介绍了通信电源系统的基本工作原理,并详细叙述了3例通信电源故障维修的过程,对通信电源输出电压偏高故障的现象进行一些探索。Communication power system is the heart of the communication system,a stable and reliable communication power supply system is key to ensure safe,reliable operation of the communication system.As soon as communication power system failure is caused by power supply interruption,communications equipment will not run,it will result in a communication circuit to interrupt the communication system to a standstill,resulting in great economic and social losses.Therefore,communication power suppy system occupies an important position in the communication system.This article describes the basic working principle of the communication power supply system,introduces the three cases of the maintenance of communications power malfunction detailedly,and explores some malfunction phenomenon of the higher output voltage of the communications power supply.
