Conductive Drone Shielding for High-Voltage Line Contact

The patent applies a thin conductive coating layer (such as conductive paint or metallic foil) on the drone's external surfaces instead of bulky conventional surge arresters. This thin film provides electrostatic shielding and discharge protection while maintaining minimal weight and structural simplicity, directly resolving the contradiction between protection reliability and device complexity

The patent replaces mechanical/electrical protection devices (surge arresters, grounding rods) with an electrostatic field-based solution using conductive coatings. The conductive surface creates a controlled electrostatic environment that naturally directs discharges away from sensitive components, substituting complex mechanical protection systems with a simpler electromagnetic field approach

The patent applies conductive material selectively on specific external surfaces of the drone where electrostatic shielding is most needed, rather than making the entire structure conductive. This localized application provides adequate shielding protection while minimizing the total conductive surface area, thereby reducing corona effect and electromagnetic interference generation

The patent designs the conductive coating with smooth, continuous surfaces and avoided sharp edges or protrusions that would concentrate electric fields. By ensuring uniform curvature and continuous conductive paths without discontinuities, the design minimizes field concentration that would otherwise trigger corona discharge, while maintaining effective electrostatic shielding
