Abstract
A separable blade for a wind turbine, the separable blade being divided at a center part thereof in a longitudinal direction into an inner blade portion corresponding to a blade root side and an outer blade portion corresponding to a blade end portion, wherein the separable blade is structured by joining the inner blade portion and the outer blade portion with a joining member made of metal, the separable blade includes: a metal plate placed between the inner blade portion and the outer blade portion and electrically connected to the joining member; and an in-blade electrical conduction wire arranged to extend from the metal plate through a blade root part of the inner blade portion to outside of the blade.

A separable blade for a wind turbine, the separable blade being divided at a center part thereof in a longitudinal direction into an inner blade portion corresponding to a blade root side and an outer blade portion corresponding to a blade end portion, the separable blade comprising:
- a joining member for joining the inner blade portion and the outer blade portion so as to structure the separable blade;
- a metal plate placed between the inner blade portion and the outer blade portion and electrically connected to the joining member;
- and
- an in-blade electrical conduction wire arranged to extend from the metal plate through a blade root part of the inner blade portion to outside of the blade.
A lightning protection device of a wind turbine with a separable blade for the wind turbine, the separable blade being divided at a center part thereof in a longitudinal direction into an inner blade portion corresponding to a blade root side and an outer blade portion corresponding to a blade end portion, the lightning protection device comprising:
- a joining member for joining the inner blade portion and the outer blade portion so as to structure the separable blade;
- a metal plate placed between the inner blade portion and the outer blade portion and electrically connected to the joining member;
- and
- an in-blade electrical conduction wire arranged to extend from the metal plate through a blade root part of the inner blade portion to outside of the blade;
- a ground metal plate;
- and
- a ground electrical conduction section for electrically connecting the ground metal plate and the in-blade electrical conduction wire of the separable blade for the wind turbine.
A separable blade for a wind turbine, the separable blade being divided into a plurality of divided blade portions, the separable blade comprising:
- at least one joining member for joining the plurality of divided blade portions so as to structure the separable blade;
- a metal plate placed between two divided blade portions located next to each other among the plurality of divided blade portions and electrically connected to one of the at least one joining member, and
- an in-blade electrical conduction wire arranged to extend from the metal plate through a blade root part of an innermost divided blade portion among the plurality of divided blade portions to outside of the separable blade.
