Wind power blade lightning protection system

The invention discloses a lightning protection system for a wind power blade. The lightning protection system comprises a lightning receiving section, a high-resistance material coating section, a conductive material net section, a grounding down lead with a protection gap and an edge protection conductor. Compared with a traditional lightning protection scheme, the technical scheme can reduce the number of lightning strokes on the wind power blade, solves the problem that the surface electric field of the wind power blade is unbalanced, prevents breakdown and electric arcs from damaging the wind power blade in the lightning stroke process, and reduces lightning stroke accidents. 本发明公开风电叶片防雷系统，包括接闪区段、高阻材料涂层区段、导电材料网区段、带保护间隙的接地引下线以及护边导体。本发明技术方案和传统防雷方案比可降低对风电叶片的雷击次数，并解决风电叶片表面电场不均衡的问题，以防止在雷击过程中击穿和电弧损坏风电叶片，减少雷击事故。
