摘要
为克服单系统供电的瓶颈问题,提升通信网络供电安全可靠性,重要直流通信设备采取双系统双路由供电(主备供电模式)。分析了直流双系统双路由供电模式的工作原理及其应用场景,并对目前要求双系统双路由供电模式的典型通信设备进行了测试验证,得出了双系统双路由供电模式运行安全可靠,并提出了双系统双路由供电模式维护建设中的注意事项。
In order to overcome the bottleneck problem of single system power supply and improve the security and reliability of communication network power supply,the important DC communication equipment adopts dual-system dualrouting power supply(main standby power supply mode).The working principle and application scenario of dual-routing power supply mode of DC dual system are analyzed,and the typical communication equipment which requires dual-system dual-routing power supply mode is tested and verified,and it is concluded that dual-routing power supply mode is safe and reliable,and the matters needing attention in the maintenance and construction of dual-routing power supply mode are put.
