An embodiment of the invention provides a wind power generating unit, a lightning protection device thereof and a lightning protection method, belongs to the technical field of lightning protection devices and aims at guaranteeing normal running of the wind power generating unit. The lightning protection device comprises a friction plate, one end of the friction plate is connected with an incoming end flange, an electroconductive disc relatively moving to the friction plate is arranged below the other end of the friction plate, an outgoing end flange is arranged below the electroconductive disc, the incoming end flange is made of an insulating material and directly or indirectly mounted on a bearing to enable the friction plate and the bearing to be insulated, and the outgoing end flange is made of an electroconductive material and indirectly mounted on the bearing to enable the electroconductive disc and the bearing to be insulated. The lightning protection device and the lightning protection method can be used for lightning protection in the wind power generating unit.
Description
technical field [0001] The invention relates to the technical field of lightning protection devices, in particular to a lightning protection device for a wind power generator, a wind power generator and a lightning protection method. Background technique [0002] With the increase of the unit capacity of the wind power generating set and the increase of the diameter of the wind rotor, the height of the wind power generating set from the ground is also increasing. So far, the height of new wind turbines has reached or even exceeded 160 meters. Since wind turbines are usually installed in high-altitude areas or coastal areas where lightning occurs frequently, wind turbines in these areas are particularly protruding objects and are vulnerable to lightning strikes. In order to prevent wind turbines from being damaged by lightning strikes, it is necessary to install lightning protection devices for wind turbines. [0003] Among the existing lightning protection devices, patent ...
