摘　　要：供电保障是广播电视安全播出保障的基础。在信号传输过程中,网络传输设备与其他信号处理设备不同,一般采用直流电源供电。现有广电机房一般采用直流电源柜或外置开关电源模块为设备供电。为取代成本高、占用空间较大的直流电源柜和可靠性较低的外置开关电源模块等供电方式,设计研发一种小型化直流电源热备份设备,可实现双外电输入、直流负载均衡输出,具备独立整流、双电源在线热备份及电源故障自动切换功能,可提高传输设备供电的可靠性。Power supply is the foundation of the safe broadcasting of radio and television. In signal transmission, network equipment is different from other signal processing equipment, and generally uses DC supply. The current radio and television equipment rooms generally use DC power rack or external switching power supply modules to supply power. In order to replace the high-cost, largeoccupied DC power supply cabinet, and the low-reliability external switching power supply module, this paper designed and developed a miniaturized DC power supply hot standby device, which can realize dual external power supply Input, load balancing, with independent rectification, dual power supply hot standby, automatic switching function under power failure, which improves the reliability of power supply of transmission equipment.
