Embodiment Construction

[0027] The blade lightning protection system and the blades of the wind power generating set according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] figure 2 It is a structural schematic diagram of the blade lightning protection system of the wind power generating set according to the embodiment of the present invention. The blade lightning protection system can be installed on different types of wind power generating sets to reduce the risk of damage to the blades when they are struck by lightning and ensure that the wind power generating set normal operation to achieve the purpose of increasing power generation.

[0029] Such as figure 2 As shown, according to the embodiment of the present invention, the blade lightning protection system includes a plurality of lightning receptors 5 arranged at intervals on the blade 1, and along the direction from the blade tip to the blade root of the b...

Abstract

The invention provides a blade lightning protection system and a blade of a wind turbine generator system. The blade lightning protection system comprises multiple lightning arresters arranged on the blade at intervals. The interval between every two adjacent lightning arresters is gradually increased from the tip to the root of the blade. By means of the technical scheme, the intervals between the adjacent lightning arresters are controlled to be gradually increased from the tip to the root of the blade, the blade tip position easily suffering from lightning strokes is subjected to key lightning protection, and the probability that the blade is damaged due to lightning strokes can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a blade lightning protection system and blades of a wind power generating set. Background technique [0002] With the continuous development of wind power generation technology, the capacity of a single unit of a wind turbine generator set continues to expand, and the length of the blades of the wind turbine generator set is also gradually lengthened. The length of conventional blades has reached more than 50m, plus the height of the hub has exceeded 100m, and the overall height of the wind turbine has reached more than 150m. Such a height causes a high risk of lightning during the operation of the wind power generating set, especially the blades of the wind generating set are easily damaged by lightning strikes. [0003] Such as figure 1 As shown, the blade lightning protection device of the wind power generating set in the prior art mainly includes the prior art...
