输电线路在线监测设备供电电源应用分析

With the increasing power consumption of on-line monitoring equipments on transmission lines,the power supply of the on-line monitoring is becoming more and more important. The power supply is the key factor to restrict the stable operation of the on-line monitoring equipments. In this paper, the traditional solar panels and battery calculation methods are analyzed. And then, some influential factors are respectively introduced,such as power consumption surge,solar panels dust,battery temperature characteristics,tower installation limits. Finally,this paper analyzes the improved method of on-line monitoring power supply, and puts forward the power supply design scheme of two typical on-line monitoring equipments. This research may provide some useful reference for the power supply design of on-line monitoring equipments.
