摘　　要：对于挂接在10 kV输电线路上的故障定位系统,由于能量不能在低压侧获取,故高压在线取能电源的设计是其最关键的技术之一。设计了一种以铁基纳米晶磁芯为核心结合电力电子技术的电源装置,利用单片机和继电器发出控制信号,来改变取电磁芯线圈的匝数以及锂离子电池的充放电,从而使输出功率稳定在一个较小的范围内,并且增加了太阳电池板等储能元件,保障故障指示器的不间断工作。The fault system attaches to the 10 kV transmission lines because the energy can not be obtained by the low voltage side, so the design of online high-voltage power supply can be the most critical technologies. A power supply units based on nano crystalline core and the power electronics technology was designed. The microcontroller and relay control signals were used to change the core turns and charge current of lithium-ion battery, so that the power output of current transformer power supply was limited in a narrow range. Finally, the solar panels and other energy storage devices were added to insure the fault indicator uninterrupted work.
