Abstract

The invention relates to an electrical connection system for a wind turbine blade, a wind turbine and a related method. The present invention relates to the electrical connection system for the wind turbine blade that allows current to be shared between all conductors in order to avoid voltage differences between them, thereby avoiding internal sparks between pultruded plates, preferably in a sparcap of the wind turbine blade. The second object of the invention is the wind turbine which in turn comprises the wind turbine blade comprising an electrical engagement system. The third object of the invention is a method for electrically connecting an electrically conductive cap in the wind turbine blade.

Description

technical field [0001] The present invention relates to an electrical connection system for a wind turbine blade which allows sharing of current between all conductors in order to avoid voltage differences between them, preferably in the spar cap of the wind turbine blade Internal sparks between pultruded sheets. [0002] A second object of the invention is a wind turbine which in turn comprises a wind turbine blade comprising an electrical joint system. [0003] A third object of the invention is a method for electrically connecting a conductive element that is part of a cap in a wind turbine blade. Background technique [0004] It is known in the prior art document US20180156202A1 which discloses a spar cap assembly for a wind turbine rotor blade having a carbon fiber reinforced spar cap, a lightning conductor extending along the spar cap and An equipotential bonding element electrically conductively connecting the spar cap and the lightning conductor together, wherein t...
