Inventors include Cui, Xiaopeng; Wang, Xiangdong; Li, Chengliang; Lu, Xiaofeng; and Li, Guoyong.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: A lightning protection system (100) for a wind turbine blade, a wind turbine blade, a wind power generation device, and a blade tip lightning receptor (10), which can improve the current carrying efficiency of conductors and reduce the consumption of conductor materials. The lightning protection system (100) is used for a blade, and the lightning protection system (100) comprises: a blade tip lightning receptor (10) comprising a first conductor portion (11) and a second conductor portion (12) which are distributed in a first direction, wherein the second conductor portion (12) is connected to the first conductor portion (11), the blade tip lightning receptor (10) can be connected to the blade tip of the blade, and at least part of the first conductor portion (11) protrudes from the blade tip; and a first lead (20) having one end electrically connected to the second conductor portion (12) and the other end extending towards a side where the blade root of the blade is located. At least one of the first conductor portion (11) and the first lead (20) is internally hollow, thereby improving the current carrying efficiency of conductor materials in the first conductor portion (11) and/or the first lead (20) in the lightning protection system (100), and reducing the consumption of the conductor materials in the lightning protection system (100).
