摘要
高频开关电源和变电站一体化电源已广泛应用于电力通信系统。文章针对蓄电池运行模式、电源防雷模式、电源接地模式和运行维护模式等方面,对这两种电力通信电源的原理和功能进行了分析和比较。并结合多年的现场经验,从通信设备重要性、电源设备安全策略和电源智能化管理3个方面,阐述了无人值守变电站通信电源系统的应用策略和配置原则。
High-frequency switching power supply and integrated power supply in substations have been applied widely in power telecommunication system. The paper analyses their functions and discusses battery running, lightning protection, grounding and operation maintenance about these two kinds of power supply. Combined with practical experiences, the paper puts forward application strategies and configuration criterions for communication power supply system in unattended substation on the aspects of the importance of communication equipment, the safety measures and the intelligent management of power supply.
