Problems solved by technology

Existing air receptors do not particularly consider the impact of tip discharge
At the same time, if the blades using this lightning protection device are damaged by lightning strikes, the blade tips will not be recoverable, and only the entire blade can be replaced, which will consume a lot of manpower and financial resources

Abstract

The invention provides a wind energy blade with a lightning arrester. The wind energy blade comprises a blade body, a movable blade tip, a fixing device, the lightning arrester and a thunder guide lead; according to the wind energy blade with the lightning arrester, the tip discharge influence is sufficiently considered, and a thunder receiving device is arranged on the movable blade tip; multipleconductor fixing bolts and the thunder receiving device form a main and auxiliary thunder receiving system, the blade tip effective thunder receiving efficiency is improved, a blade body is preventedfrom being damaged, and the high temperature damage of work of the main and auxiliary thunder receiving system to the surface of the blade body can be reduced; the movable blade tip is adopted, if the lightning stroke appears and the blade tip is damaged, the whole blade does not need to be replaced, only the movable blade tip is replaced, and manpower and financial resource consumption is greatly reduced.

Description

technical field [0001] The application relates to clean energy equipment, in particular to a wind energy blade with a lightning protection device. Background technique [0002] One of the most critical issues in the reliability of wind turbines is lightning protection. As the height of wind power generation and generator power increase, the probability of lightning strikes on wind turbines will also increase. The most dangerous part of wind power components is the fan blade, so the design of the lightning protection device for the blade is particularly important. [0003] At present, the existing lightning protection devices for wind energy blades are provided with lightning receptors at the tip of the blades, which are used to guide lightning to the lightning receptors, and then lead them to the ground through down conductors connected thereto. Existing air receptors do not particularly consider the impact of tip discharge. At the same time, if the blade tip of the lightn...
