Abstract

The invention relates to a lightning protection device, a lightning protection system, a wind generating set and a forming method. The lightning protection device comprises a transition conductor, wherein the transition conductor has a preset length and is provided with a first connecting end and a second connecting end which are opposite in the length direction of the transition conductor, the transition conductor comprises a plurality of conductive sections which are arranged in succession, and the current conduction capability of the multiple conductive sections is in an increasing trend in the arrangement direction from the first connecting end to the second connecting end. According to the lightning protection device, the lightning protection system, the wind generating set and the forming method in the embodiment, the blade protection requirement can be reliably met, and safe operation of the wind generating set is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a lightning protection device, a wind power generating set and a forming method. Background technique [0002] Because lightning can cause damage to towering buildings, for example, with the continuous development of wind power technology, the size of wind turbines continues to increase, and the damage to blades caused by lightning strikes increases. Correspondingly, in order to prevent the blades from being struck by lightning as much as possible, it is necessary to set up corresponding protective devices, guide the current to the down-conductor system through the protective device, and finally conduct the current to the earth through the down-conductor system, so as to ensure the safe operation of the wind turbine . [0003] However, due to the unreasonable structural design of the lightning protection device in the prior art, when the protection device is connected to the ...
