Abstract

The invention discloses an impeller lightning protection device for a wind generating set. The impeller lightning protection device comprises a small size lightning protection bracket which is installed on a wheel hub and rotates along with the wheel hub, an introduction carbon brush and an extraction carbon brush are installed on the lightning protection bracket, wherein the introduction carbon brush is used for introducing thunder and lightning to a variable pitch blade, and the extraction carbon brush is connected with the introduction carbon brush and used for conducting the thunder and lightning to a motionless wind wheel locking flange. An auxiliary conductive device is installed on the lightning protection bracket and comprises a first arc striking electrode and a second arc striking electrode, wherein the first arc striking electrode is used for introducing the thunder and lightning on the variable pitch blade, and the second arc striking electrode is connected with the first arc striking electrode and used for conducting the thunder and lightning introduced by the first arc striking electrode to the motionless wind wheel locking flange. The impeller lightning protection device for the wind generating set provided by the invention aims to solve the problems of large size, complex structure, difficult manufacture and installation and the like of the traditional impeller lightning protection device and has the characteristics of low cost, simple structure, convenience for installation and the like.

Description

[technical field] [0001] The invention relates to a lightning protection device, in particular to a lightning protection device for an impeller of a wind power generating set. [Background technique] [0002] Generally, wind turbines are designed and manufactured independently of the lightning protection device of the impeller itself and the lightning protection device connected to the main transmission chain. In this way, the design and manufacture of the lightning protection device of the impeller system is subject to the external dimensions and dimensions of the blades, hubs and main transmission chain. Due to the limitation of structural form, it is often bulky or complex in structure, and the cost of manufacturing and installation is also high. [Content of the invention] [0003] The present invention overcomes the disadvantages of the above-mentioned technologies, and provides a wind turbine impeller lightning protection device to solve the problems of the existing im...
