Background technique
The lightning protection of wind generator set blade is the difficult problem of puzzlement wind-power electricity generation industry always, traditional Lightning Protection is slug to be installed as arrester on blade, utilize the cable of blade interior to carry out the conduction of lightning current simultaneously, and find by a large amount of practice operations, this blade with lightning protection function after connecing sudden strain of a muscle often because of the heating of slug, the through-current capacity deficiency of cable causes bursting of blade, phenomenons such as cable breakage, and adopt the mode of conductive carbon fibre because the lightning current heating causes slug blade on every side to deform, the influence of serious cracking the normal operation of wind power generating set, increased maintenance cost.
Summary of the invention
The utility model can overcome the deficiencies in the prior art, proposes a kind of lightning protection blade of wind power generating set, plays good lightning protection effect.
Lightning protection blade described in the utility model comprises basic unit, arrester and conductive mesh.Wherein, basic unit is provided with arrester, and substrate surface is coated with conductive mesh, and conductive mesh is connected with arrester.
Concrete, described arrester is the disc type gas discharge tube, is placed on the plate-like base by two plate electrodes, the plate-like base reliably is connected with conductive mesh.Basic unit mainly is the framework layer of the blade that is made of glass fibre reinforced plastic material.Adopt screw to fix between plate-like base and the basic unit.Conductive mesh is the metal grill with specification spacing, and the netting twine diameter of metal grill is not less than 1.5mm.Blade pass is crossed flange connecting apparatus and is connected with flange, and conductive mesh and flange connecting apparatus are electrically connected.Conductive mesh, blade flange connection set and flange constitute conductive layer.Blade conductive mesh surface is provided with protective layer, and receptor surface is exposed to outside the protective layer.
The beneficial effects of the utility model are:
The first, the arrester of new blade has adopted the disc type gas discharge tube, and the feasible intensity that is diverted to the lightning current of conductive layer is effectively reduced, and has also reduced the transient high temperature that forms on arrester simultaneously;
The second, the cancellated shunting action of conductive layer has reduced the intensity of Lightning Electromagnetic Pulse, and can prevent because the transient high temperature of conductive layer causes cracking between blade basic unit, conductive layer and the protective layer, bursts phenomenon;
Three, new blade has been cancelled the earial drainage cable that uses in the traditional approach, and the high Lightning Electromagnetic Pulse that forms when having reduced earial drainage is to the intrusion of equipment in the cabin.
