Wind turbine rotor blade having a heating element and a method of making the same

摘要

The invention relates to a wind turbine rotor blade having a blade root, a blade tip, two interconnected rotor blade half shells, which include a fiber-reinforced plastics material, and an electrical heating element, which is arranged on an outer side of the rotor blade and has a blade root end and a blade tip end, wherein the blade tip end is connected via an electrical line leading to the blade root and at least a first segment of the electrical line, which is arranged on an inner side of one of the rotor blade half shells, is made of a carbon fiber material. Further, the present invention relates to a method for making a wind turbine rotor blade having an electrical heating element.

主权项

1. A wind turbine rotor blade comprising:
a first and a second rotor blade half shell each having an inner side and an outer side and which include a fiber reinforced plastics material; said first and said second rotor blade half shells being mutually joined to conjointly define an inner side and an outer side of the rotor blade and to conjointly define a blade root and a blade tip; an electrical heating element arranged on one of the outer sides of the rotor blade and having a blade root end and a blade tip end; an electrical line leading to said blade root; said blade tip end of said electrical heating element being connected via said electrical line; said electrical line having a first segment arranged on said inner side of one of said rotor blade half shells and said first segment being formed of carbon fiber; said electrical line having a second segment arranged on said outer side of the rotor blade; said second segment of said electrical line being made of a carbon fiber material; said second segment having a region which contacts said blade tip end of said heating element; and, wherein said heating element has an under side and a top side; and, said second segment has a region which is guided around said heating element so as to contact said under side and said top side of said heating element.
