Abstract

The invention discloses a wind power blade lightning protection system and a wind power blade. The wind power blade lightning protection system includes a metal mesh laid on the surface of the wind power blade. There are multiple layers of additional metal mesh overlapping the metal mesh, and a metal belt is sandwiched between the metal mesh and the additional metal mesh and between the additional metal mesh of the adjacent layer, and multiple metal belts extend into the wind turbine blades. Twist into a strand in the cavity and connect with the down conductor. The wind power blade lightning protection system and the lightning protection wind power blade can reduce the degree of sudden change in resistance from the metal mesh to the metal strip, thereby reducing the impact of the lightning current on the vicinity of the connection of the metal strip during the process of lightning current conduction from the metal mesh to the down conductor. area of ​​metal mesh damage.

Description

technical field [0001] The invention relates to the technical field of lightning protection for wind power blades, in particular to a lightning protection system for wind power blades and a lightning protection wind power blade. Background technique [0002] At present, the blades of wind turbines all include a lightning protection system. The lightning protection system is mainly composed of lightning receptors installed on the surface of the blade and wires inside the blade body. The lightning receptor receives lightning and connects to the lightning protection system of the whole machine through wires, so as to prevent the blade body FRP from being struck by lightning. [0003] With the advancement of blade technology, especially the use of carbon fiber blades, metal mesh is more and more used in the blade lightning protection system. By laying metal mesh on the surface of the blade, the metal mesh is connected to the lightning protection system through the down conductor...
