应用于超(特)高压输电线路智能巡检无人机的技术研究

Technical research on intelligent inspection drones applied to ultra-high voltage transmission lines

近年来,随着超(特)高压电力系统的迅速发展,自然灾害对电力系统的危害逐步凸显。500 kV及以上的超(特)高压输电线路因电压等级高和输电距离远,且因地势原因输电线塔架之间距离在5~10 km,因电压等级高、输电线缆张力等原因高度将近20 m,山西地区地形复杂,雨雪和冰冻灾害造成输电线路大范围覆冰,从而引发线路跳闸,造成大面积停电。为消除电力设备安全隐患,巡线运维人员采取登塔走线,利用敲击等方式进行人工除冰,危险系数高且工作效率低。通过无人机智能无线充电技术,消除线路及电力设备冰冻隐患,提高除冰效率,降低人力成本,确保电力系统稳定运行。

In recent years,with the rapid development of ultra-high voltage power systems,the harm of natural disasters to power systems has gradually become prominent.Due to the high voltage level and long transmission distance of 500 kV and above ultra-high voltage transmission lines,and due to terrain reasons,the distance between transmission line towers is 5~10 km,and the height is nearly 20 m due to high voltage level and transmission cable tension.The terrain in Shanxi region is complex,and rain,snow,and ice disasters cause large-scale icing on transmission lines,leading to line tripping and large-scale power outages.To eliminate safety hazards in power equipment,line patrol and maintenance personnel adopt tower climbing and manual de icing methods such as tapping,which has a high risk factor and low work efficiency.By using unmanned aerial vehicle intelligent wireless charging technology,the hidden dangers of line and power equipment freezing are eliminated,the de icing efficiency is improved,labor costs are reduced,and the stable operation of the power system is ensured.
