开关电源冗余方式探索

Research on Redundancy Mode of Switching Power Supply

随着通信业务的不断发展,直流设备的应用范围日益广泛。开关电源因其稳定高效的特点,大量应用在各种直流电源系统中,成为通信行业中最具代表性的直流供电设备。目前开关电源的备份普遍采用N+X模块冗余形式,优点是建设、维护成本较低,但开关电源的进线来源单一,成为其维护过程的薄弱环节,同时给割接改造工作带来挑战。文章针对开关电源备份方式进行探索,寻求更安全可靠的方案。

With the continuous development of communication services,DC equipment is widely used.Due to its stable and efficient characteristics,switching power supply is widely used in various DC power supply systems,and has become the most representative DC power supply equipment in the communication industry.At present,N+X module redundancy is widely used in the backup of switching power supply,which has the advantage of low construction and maintenance cost.However,the single source of incoming line of switching power supply has become the weak link in the maintenance process,which brings challenges to the cutover transformation.This paper explores the backup mode of switching power supply to seek a more secure and reliable scheme.
