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

The blade of wind-driven generator lightning arrester
Technical field
The invention belongs to lightning-arrest for blade of wind-driven generator, prevent the equipment of the thunderbolt of blade of wind-driven generator.
Background technique
People more and more pay attention to the utilization of renewable energy sources, use wind-force to do dynamic power and become the new selection of people as other mechanical power, because wind-driven generator need to be installed in the high-altitude of open space, summer, the thunderbolt meeting caused damage to blade of wind-driven generator, so the lightning-arrest important topic that becomes the development wind-powered electricity generation of blade of wind-driven generator.Existing wind-driven generator lightning arrester has plenty of and adopts on blade tip metal material for coating etc., its poor electric conductivity, and corrosion-resistant, working life is short.
Summary of the invention
In order to overcome existing wind-driven generator lightning arrester poor electric conductivity, poor corrosion resistance, the deficiency that working life is short, the invention provides a kind of blade of wind-driven generator lightning arrester, this blade of wind-driven generator lightning arrester has used new material, not only conduct electricity very well, and corrosion resistance and good, long service life.
The technical solution adopted for the present invention to solve the technical problems is: the blade of wind-driven generator lightning arrester, comprise blade of wind-driven generator, it is characterized in that: the blade lightning-protection device that the aluminium magnesium copper alloy that uses adhering with epoxy resin is cast into is equipped with at the blade of wind-driven generator tip, this lightning arrester is connected with cable by cable fixing bolt, cable connecting the middle part receiver and be connected wind-driven generator.
The front end that is shaped as of described lightning arrester blade tip plan view is that the triangle rear end is trapezoidal assemblying body, and its centre section is that the front end angle is the triangle of 10-15 degree, and the rear end is the identical trapezoidal assemblying body of angle.
Blade lightning-protection device disclosed by the invention is the performance requirement according to the blade of wind-driven generator lightning arrester, by changing the aluminum alloy chemical composition proportioning, and then change the aluminum alloy internal organizational structure, develop a kind of novel aluminum alloy material blade lightning arrester to satisfy its usability requirement.
The invention has the beneficial effects as follows: at the blade lightning-protection device that install foremost, that be cast into adhering with epoxy resin aluminium magnesium copper alloy together of blade of wind-driven generator, have good electric conductivity and decay resistance preferably, lightning-arrest effective, long service life is that to guarantee that blade of wind-driven generator prevents from being struck by lightning key novel.
