Lightning arrester of blade of wind-driven generator

Abstract

The invention discloses a lightning arrester of a blade of a wind-driven generator, and belongs to novel-material lightning arresters of blades of wind-driven generators. The lightning arrester of the blade of the wind-driven generator comprises the blade of the wind-driven generator, and is characterized in that a lightning arrester body of the blade is arranged at a tip of the blade of the wind-driven generator, aluminum, magnesium and copper alloy pieces adhered with one another via epoxy resin are subjected to die-casting to form the lightning arrester body of the blade, the lightning arrester body of the blade is connected with cables by cable fixing bolts, and the cables are connected with middle receivers and are connected with a main cable of a lightning protection device connected onto a support of the wind-driven generator. The lightning arrester of the blade has the advantages that the lightning arrester is excellent in conductivity, good in corrosion resistance and lightning protection effect and long in service life, and is a novel critical product for guaranteeing the blade of the wind-driven generator against lightning stroke.

Description

technical field [0001] The invention belongs to lightning protection for blades of wind power generators and equipment for preventing lightning strikes of blades of wind power generators. Background technique [0002] People are paying more and more attention to the use of renewable energy. Using wind power for power generation and other mechanical power has become a new choice for people. Since wind turbines need to be installed at high altitudes in open areas, lightning strikes in summer will cause damage to wind turbine blades. Therefore, the lightning protection of wind turbine blades has become an important issue in the development of wind power. Some of the existing lightning protection equipment for wind power generators use metal materials coated on the tip of the blade, which have poor electrical conductivity, poor corrosion resistance, and short service life. Contents of the invention [0003] In order to overcome the disadvantages of poor electrical conductivit...
