近年来，无人机已经证明了其自主有效解决复杂任务的能力。无人机尚未成为解决这些任务的普遍技术。原因主要是飞行时间有限。如果能够增加飞行时间，该技术在许多领域都具有巨大的市场潜力。然而，只有少数充电解决方案可用，但没有用于电力线充电的解决方案。目前这仍然是一个研究课题。本文提出了一种基于电感耦合的新型能量收集设计，允许无人机抓住并栖息在架空电线上为其电池充电。整体电子设计基于在实验室测试之前对不同电流互感器进行仿真分析和仿真。包括绕组的分体铁芯被集成到夹紧机构中，并通过解析和数值分析以及无损和破坏性测试进行验证。结果表明，可以从电力线收集足够的电力来为无人机电池充电。理论上可实现的功率也被发现在预期范围内。通过这种设计，无人机可以在未来解决耗时且复杂的任务。
In recent years drones have proven their ability to solve complex tasks autonomously and effectively. Drones have not been present as a ubiquitous technology for solving these tasks yet. The reason is mainly due to their limited flying time. The technology has great market potential in many areas if flight time could be increased. However, only a few solutions for recharging are available, but none for recharging on power lines. This remains a research topic for now. Through this paper a novel energy harvesting design is presented based on inductive coupling, allowing a drone to grasp and perch onto an overhead power line to recharge its batteries. The overall electronic design was based on analyzing and simulating different current transformers in simulation before testing in the laboratory. The split-core including windings was integrated into a gripping mechanism, verified by analytical and numerical analysis as well as non-destructive and destructive testing. The results indicate that enough power can be harvested from the powerline to recharge the drone batteries. The theoretically achievable power was also found to be within the expected range. With this design, drones can solve time-consuming and complex tasks in the future.
