摘要
为确保铁路通信电源系统安全可靠,提高设备运行效率,对铁路通信机房电源系统实施优化。对车站通信机房大容量通信高频开关电源增配一套开关电源实现双系统直流供电;区间基站、中继站通信机房等小容量高频开关电源技术改造两路输入交流电源分别给整流器模块分组供电,整流模块以N+N方式工作,直流母排并联输出满足负载冗余供电,大大提高了直流负载供电的安全性。
In order to ensure the safety and reliability of the railway communication power supply system and improve the efficiency of the equipment,the optimization of the railway communication room power supply system is carried out.A set of switching power supply is added to the station communication room’s large-capacity communication high-frequency switching power supply to achieve dual system DC power supply;The low-capacity high-frequency switching power supply technology such as the interval base station and the relay station communication room is reconstructed.The two-way input AC power supply supplies the rectifier module separately.The rectifier module works in the N+N mode,and the DC bus output in parallel satisfies the load redundancy power supply.It greatly improves the security of DC load power supply.
