BeskrivelseDescription

BenævnelseDenominations

Vinge til vindmølle til el-produktion opvarmet ved hjælp af et kulfiberlag. Opfindelsens anvendelsesområdeBlade for wind turbine for electricity generation heated by a carbon fiber layer. Field of application of the invention

Opfindelsen er en vindmøllevinge, som opvarmes elektrisk ved at udnytte et kulfiberlags evne til at lede elektricitetThe invention is a wind turbine blade which is electrically heated by utilizing the ability of a carbon fiber layer to conduct electricity

Formålet med at opvarme vindmøllevingen er at forhindre begrænsning af effekten og forøgelse af belastningen som følge af Isdannelse.The purpose of heating the wind turbine blade is to prevent limiting the effect and increase the load due to Ice formation.

Kendt teknikPrior art

Opvarmning af et vindmøllevinge ved hjælp af et lamelformet varmeelement, som limes udvendig på vingen, er allerede kendt.Heating of a wind turbine blade by means of a slat-shaped heating element which is glued to the outside of the blade is already known.

Det tekniske problem som skal løsesThe technical problem to be solved

Den korte levetid er en ulempe ved et sådant varmeelement.The short service life is a disadvantage of such a heating element.

For eksempel beskadiges varmeelementet let af slag fra isklumper.For example, the heating element is easily damaged by blows from ice clumps.

Den ny teknik I denne opfindelse sker opvarmningen ved hjælp af et kulfiberlag, som er placeret under vingens yderlag, beskyttet mod sammenstød med isklumper og andre ydre påvirkninger.The New Technique In this invention, the heating is effected by means of a carbon fiber layer, which is located under the outer layer of the blade, protected from impact with ice clumps and other external influences.

Det opvarmende kulfiberlag kan, hvis det forsynes med passende belægning, også påføres på vingens yderside. Takket være kulfiberens store holdbarhed modstår den slag fra is betydeligt bedre end et lamelformet varmeelementThe heating carbon fiber layer, if provided with suitable coating, can also be applied to the outside of the blade. Thanks to the high durability of the carbon fiber, the impact of ice withstands much better than a slat-shaped heating element

De tekniske virkninger Få grund af kulfiberlagets homogene struktur forhindres opvarmningen ikke af huller forårsaget af sammenstød med store isklumper.The technical effects Due to the homogeneous structure of the carbon fiber layer, heating is not prevented by holes caused by clashes with large ice clumps.

Idet vingerne som regel fremstilles ved laminering af glasfiber, kan kulfiberlaget påføres i forbindelse med den normale produktionsproces.As the blades are usually made by laminating fiberglass, the carbon fiber layer can be applied in the normal production process.

På et senere tidspunkt kan kulfiberlaget lamineres fast pi vingernes yderside og beskyttes med et passende yderiag. El-ledningerne tilsluttes til kulfiberlaget på steder, som bestemmes af den ønskede fordeling af effekten.At a later stage, the carbon fiber layer can be laminated firmly to the outside of the wings and protected with a suitable outer layer. The power lines are connected to the carbon fiber layer at locations determined by the desired distribution of power.

Opfindelsen er kendetegnet ved det, der opgives i den vedhæftede beskyttelseskravs afsnit om kendetegn samt figurer.The invention is characterized by that which is stated in the section on the characteristics and figures of the attached protection claim.
