被忽略的交换机双路供电模式

The neglected two ways power supply mode of switch

在信息网络领域中,网络设备对供电要求越来越高,为了保证设备的供电可靠性,电源系统备份问题显得尤为重要。本文充分利用了网络设备容易被忽略的直流输入技术,构建与实施交直流双路供电的新型交换网络。通过仿真和现场运行测试表明,交直流双路供电用于解决后端高可靠供电需求问题的方案是可行的。

In the field of information network, network equipment is increasingly demanding power supply. In order to ensure thereliability of power supply, power system backup becomes increasingly important. This paper introduces the construction andimplementation of a new switching network with AC and DC power supply by making full use of DC input technology which iseasily ignored by network equipment. The simulation and field operation test show that the AC-DC dual - circuit power supplyscheme is feasible to solve the problem of high reliable power supply demand at the back-end.
