Wind turbine rotor blade having an electrical heating device and a plurality of lightning conductors

Abstract

A wind turbine rotor blade includes: a rotor blade root; a rotor blade tip; an electrical heating device; a first lightning receptor disposed in the region of the rotor blade tip; precisely two lightning conductors leading from the lightning receptor to the rotor blade root; a second lightning receptor arranged at a distance to the rotor blade tip and connected to one of the lightning conductors; and, each one of the two lightning conductors being electrically conductively connected to the electrical heating device at a multiplicity of points between the rotor blade root and the rotor blade tip so as to cause equipotential bonding between the two lightning conductors via the electrical heating device in response to a lightning strike to the rotor blade.
