| 摘 要： | 通过高频开关电源的模块化技术、并联技术、提高开关频率技术等手段,优化结构,统一监控,将变电站电源多套设备集成在一套设备内.在直流操作电源中,因为合闸电力的减小,取消了降压装置;通信电源和逆变电源中,通过多模块并联提高可靠性,取消了蓄电池;形成了电源设备的一体化系统.电源设备一体化以后直接降低成本30%以上,提高电源系统的可靠性、可用性和可维护性.

| Abstract: | With the new technologies of modularization,paralleling and high-switching frequency,multiple power supply equipments of substation are integrated into one device,which has optimized structure and is centrally monitored.As the switching current is reduced,the voltage-dropping device of DC power supply for operation is removed;as the reliability is improved by the paralleling of multiple modules,the batteries of power supply for communication and inverter are removed.The integrative solution for substation p... |
