随着电力系统基础设施的老化，输电线路检查变得越来越重要，因为主动识别线路维护需求对于最大限度地减少停电至关重要。利用机器人进行此类检查对人类来说更安全，而且劳动力成本更低，但找到合适的在线机器人设计也面临着一系列挑战。本文提出了一种非接触式输电线路检查系统，其中无人机（UAV）执行所有检查活动，同时通过感应电力传输从线路充电。针对该充电应用，提出并测试了两种线圈设计——一种具有空气芯，一种具有线封闭芯夹。最后，讨论了与每种设计相关的优点和挑战，以及通过无人机应用传输线进行感应充电的一般实用性。
Transmission line inspection becomes increasingly more important as power system infrastructure ages because proactively identifying line maintenance needs is crucial for minimizing outages. Utilizing robots to conduct such inspections is both safer for humans and less costly in terms of labor, but finding an appropriate on-line robot design presents its own set of challenges. This paper proposes a touch-free transmission line inspection system in which an unmanned aerial vehicle (UAV) conducts all inspection activities and, while doing so, charges from the line via inductive power transmission. Two coil designs are presented and tested for this charging application - one with an air core and one with a line-enclosing core clamp. Finally, the benefits and challenges associated with each design are discussed, along with the general practicality of inductive charging via transmission lines for UAV applications.
