Lightning protection device of pitch control system accessories

Abstract

The invention discloses a lightning protection device of pitch control system accessories. The lightning protection device is characterized by being formed by a power collector plate, a carbon fiber brush and a gasket pressing plate; a base plate of the carbon fiber brush plate is fixed in the middle of the front edge of the power collector plate through a screw in a stacked mode; the gasket pressing plate is fixed in the middle of the upper plate surface of the power collector plate through a bolt in a stacked mode. According to the lightning protection device of the pitch control system accessories, the lightning electric charge quantity can be effectively absorbed and released through a power collector claw, meanwhile the electric charge produced in the operation process of a pitch control system is released through a spark discharger, and accordingly the lightning stroke of an insulator, a lead and a fan circuit which are arranged in the pitch control system can be effectively prevented, the structure is simple, the maintenance is convenient, and the installation is easy.

Description

technical field [0001] The invention relates to an improvement of a lightning protection device for wind power generation, in particular to a lightning protection device for accessories of a pitch control system. It mainly prevents lightning strike damage to insulators and wires in the pitch control system of wind power generation blades and its fan lines. Background technique [0002] With the continuous improvement of wind power generation technology and China's continuous support for wind power generation, wind turbines are widely used in China. Wind turbines are often distributed in relatively high areas such as mountains, hills, plateaus, or open areas such as coastal areas, where the probability of lightning strikes is high. Since the height of the wind turbine itself is generally above 100 meters, and the pitch control system is located at the top of the wind turbine, it is easier to Lightning is induced and struck by lightning, which damages the wind turbine, causin...

AI Technical Summary

Problems solved by technology

The disadvantage of this lightning protection device is that since the insulators and wires in the pitch control system also serve as grounding conductors, the insulators and wires in the pitch control system and their fan lines are more likely to be damaged when lightning strikes

[0003] It can be seen from the search that although there are reports on various lightning protection devices for wind turbines, there is no report on the lightning protection devices for the insulators and wires in the pitch control system and the protection of the fan line.
