Description

A kind of blade lightning protection device of wind-driven generator
Technical field
The utility model belongs to technical field of wind power generator, the blade lightning-protection dress of more particularly to a kind of wind-driven generator Put.
Background technology
Protruding parts relative to the earth are all formd in wind electricity blade industry, as assembling is latter, such as install in ridge, Depletion region installation etc., this just brings the problem of meeting is by thunderbolt.Current blower fan tower barrel height is universal in more than 60m, for big Type blower fan, such as 2.0MW blower fans, its blower fan tower barrel height reach more than 80m relative to ground, length of blade generally also 50m with On, operationally, the extreme higher position of blade tip can reach 130m relative ground level to blade, therefore blade meets thundery sky air exhaustion Thunder and lightning is subject to wound.In order to prevent blade from being hit by thunder and lightning, traditional lightning-arrest mode is lightning-arrest at one built in blade interior Wire, designs some arresters on the surface of blade, and arrester with lightning conductor by being connected, then passes through wheel hub and the earth phase Even.Blade is expected when by thunder and lightning by this mode, thunder and lightning the earth can be imported.However, with length of blade gradually Peak position and speed of service increase at increase, blade tip, in thunderstorm weather, blade tip is influenceed by electric field, in blade tip Substantial amounts of negative electrical charge is assembled in trailing region, forms and extra connects flash-point.Therefore, this region is easily subject to attacking to thunder and lightning Hit, so as to cause the damage of blade.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide a kind of blade of wind-driven generator Lightning arrester, its technical problem to be solved is to make blade tip when by being struck by lightning, and can imported into effectively and rapidly thunder and lightning Greatly, so as to avoid blade damage.
To achieve the above object, the utility model uses following technical proposals:A kind of blade lightning-protection dress of wind-driven generator Put, including blade, lightning conductor, metal net layer and blade tip arrester, described blade tip arrester is bonded in vane mold matching At blade tip on housing, it is characterised in that:Also include metal connecting plate and connecting bolt, described metal net layer is in blade life The outside for the glass layer of cloth being laid on during production in blade tip, described metal connecting plate is built in the inside of blade, metal connecting plate One end be connected with metal net layer, the other end of metal connecting plate is connected by connecting bolt with blade tip arrester.
Metal net layer described in the utility model is laid at blade tip trailing edge 0-5m regions.
Metal connecting plate described in the utility model is aluminium sheet.
Compared with prior art, the beneficial effects of the utility model have:By the metal net layer and gold that add tip region Belong to connecting plate, added to blade tip and more connect sudden strain of a muscle area, when occurring thunder-strike phenomenon, metal net layer various pieces can be effective Scattered thunder and lightning produce electric current, while by metal connecting plate-blade tip arrester-lightning conductor-complete machine take shelter from the thunder system, by thunder Conductance enters the earth.Under the high original-assemblied machine environment that atmospheric electrical phenomena takes place frequently, the utility model does not influence leaf appearance, substantially not increased Leaf weight, negative effect is not produced, effectively raise the lightning-arrest effect of blade tip arrester, be particularly suitable for use in Yunnan-Guizhou valley area The wind field that atmospheric electrical phenomena takes place frequently.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1- metal net layers, 2- metal connecting plates, 3- blade tip arresters, 4- connecting bolts, housing, 6- at 5- blade tips Lightning conductor.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described, but is not limited to embodiment.
As shown in figure 1, a kind of blade lightning protection device of wind-driven generator described in the utility model, including it is blade, lightning-arrest Wire, metal net layer, blade tip arrester, metal connecting plate and connecting bolt.
Described blade tip arrester is bonded in vane mold matching on the SS faces of housing at blade tip, according to just after bonding Permanent current journey carries out matched moulds, and described lightning conductor is passed through to be connected at blade tip behind the space of housing with the lightning protection system of wind-driven generator Connect.
Described metal net layer is the outside that glass layer of cloth in blade tip is laid on when blade is produced, and metal net layer is laid on At blade tip trailing edge 0-5m regions, metal net layer is formed from aluminium.After metal net layer laying, the measures such as glue spraying are taken to do appropriate consolidate It is fixed, prevent from sliding in subsequent operation, then carry out laying, perfusion according still further to the normal blade mode of production and solidify.Metal Stratum reticulare electric conductivity itself is strong, and when some point of metal net layer receives moment large charge, electric charge can be disperseed into conduction rapidly, And metal net layer has good flexibility in itself, leaf can not be influenceed in the integrated filling process of fiberglass well with type The outward appearance and quality of piece.
Described metal connecting plate is built in the inside of blade, and one end of metal connecting plate is connected with metal net layer, gold The other end of category connecting plate is connected by connecting bolt with blade tip arrester.Metal connecting plate will have good electric conductivity and can Operability, the utility model uses aluminium sheet, by aluminium sheet and connecting bolt, makes shape between metal net layer, aluminium sheet, blade tip arrester It is connected into a lightning protection system, and in the use of blade later stage by built-in lightning protection system with the earth, so as to efficiently solve Blade tip in thunderstorm weather by thunderbolt the problem of.
