Thunder system effectively connects that sudden strain of a muscle rate is not high, and the spoilage of blade is up to 70% or so；Traditional wind power blade lightning protection is mainly by blade
Sophisticated metallic receptor, single or more lightning-guide cable of blade interior laying, IEC61400-24《Wind power generating set thunder
Electricity protection》The standard of arrangement, line footpath in to(for) blade interior downlead have done more clearly regulation, but this basic
Fixed form still can not be obviously improved the broken by lightning ratio of blade body.Therefore, for the lightning-protection system of blade
It is badly in need of a kind of new lightning protection device, connecing sudden strain of a muscle rate with raising reduces it because of thunder spoilage, so as to improve the outer surface thunder and lightning of blade
Conduction and evacuation, the application take a kind of outside for increasing blade surface flashover ability and connect sudden strain of a muscle, conduction lightning-protection blade.
Conducting resinl is a kind of adhesive for solidifying or having certain electric conductivity after drying, and it generally with matrix resin and leads
Electric filler is that conducting particles is main constituents, conducting particles is combined together by the bonding effect of matrix resin, shape
Into conductive path, being conductively connected by viscous material is realized.Because the matrix resin of conducting resinl is a kind of adhesive, can select to fit
Suitable solidification temperature is bonded, simultaneously as the miniaturization of electronic component, miniaturization and the densification of printed circuit board (PCB) and
Highgrade integration develops rapidly, and slurry can be made in conducting resinl, realizes very high linear resolution.And conductive adhesive process letter
It is single, it is easily operated, production efficiency can be improved, so conducting resinl is to substitute slicker solder welding, realizes the ideal chose being conductively connected.
Traditional conducting resinl mainly based on matrix resin and conducting filler, wherein conduction fill out it is more with a kind of metal or
Based on semiconductor；Such a conducting resinl can not be applied in the conduction field of high current especially lightning current, easily lost because of super-high-current
Effect；It is existing also to have the conducting resinl containing various metals conductive filler on the market, but heat conduction, electric conductivity be present not as metal glues
The problem of connecing.Medium temperature heat-insulating material, temperature in use is between 100~700 DEG C.Medium temperature fibrous material have aerogel blanket,
Asbestos, mineral wool and glass fibre etc.；Porous material has calcium silicates, expanded perlite, vermiculite and foam concrete etc..
