摘要:笔者研制了一种基于输电作业无人机的带电拆除金属飘挂物装置,并在实际工作应用中验证其可行性。输电线路往往在野外运行,所处环境复杂,在风力比较大的天气,一些重量较轻的金属漂流物经常会被吹至输电线路上,形成飘挂物,极易造成输电线路相间短路或单相接地短路导致线路跳闸事故。而与传统的人工清除飘挂物方式相比,利用输电作业无人机,一方面提升了作业的效率,一方面也规避了人身的风险。

Abstract: A device for live removal of metal floating objects based on transmission UAV is developed, and its feasibility is verified in practical application。Transmission lines often operate in the field and the environment is complex. In the weather with strong wind, some lighter metal drifts are often blown onto the transmission line to form floating objects, which is very easy to cause phase to phase short circuit or single-phase grounding short circuit of the transmission line, resulting in line tripping.Compared with the traditional manual removal of floating objects, the use of power transmission UAV not only improves the efficiency of operation, but also avoids personal risks.

1研究背景
随着我国经济与社会的蓬勃发展,电力行业作为工业化的基础及民生的保障迅速发展,但输电线路越发面临多样的外部环境与外部隐患。随着输电线路的建设,外力破坏成为输电线路运维不可逃避的严峻难题。据统计显示,外力破坏造成的电网事故呈现逐年增长的趋势,严重影响了供电可靠性。造成外力破坏的重要原因之一是物体飘挂在导线上引起线路跳闸,飘挂物往往是一些广告牌、铁皮、风筝等重量较轻的物体[1]。特别是在大风天气,输电线路周围菜地使用的大棚、临时厂棚搭载不牢固的铁皮、含有金属成分的废弃广告牌、垃圾场的部分垃圾等都是输电运维面临的安全隐患。并且,广东地处沿海,夏季经常面临台风恶劣天气,一旦有物体飘挂在导线上极易造成线路跳闸,所以输电运维中必须考虑飘挂物的应急处置。……
