摘要
介绍了兰州供电公司110 kV树屏变电站在改造过程中,取消通信专用直流电源系统和蓄电池组,利用变电站直流电源装置为通信设备供电的具体案例。详细分析了采用变电站用直流系统为通信设备供电的方案、DC/DC变换器的主要工作原理和技术参数,使用后的优缺点和实际使用效果等,为今后利用电力装置为通信设备供电提供了一种新的尝试。
During the upgrading of 110 kV Shuping substation of Lanzhou Power Supply Company, instead of using DC power supply system and the batteries dedicated for communication system, substation DC power supply devices were used to provide power for communication equipment. This article analyses the technical scheme, main working principle of DC/DC converter and technical parameter, discusses the advantages, disadvantage as well as the application effects. It laid an experimental foundation for the power supply of communication equipment in power system and the equipment needs -48 V power supply.
