Abstract
The disclosure relates to a carbon blade for a wind turbine with multiple down conductors, and more particularly, to a carbon blade for a wind turbine with multiple down conductors that includes multiple down conductors disposed thereon to reduce or prevent a potential difference between a plurality of points to be formed thereon from being generated.
Claims15
A carbon blade for a wind turbine, comprising:
- a carbon spar cap disposed at the center of a width of the blade and extending in a longitudinal direction of the blade;
- a carbon skin extending from a tip of the blade to a root of the blade to cover an outer surface of the blade;
- a first down conductor disposed on a surface of the blade and partially covering the carbon spar cap in parallel with the carbon spar cap;
- a second down conductor disposed on an inner surface of the blade;
- and
- a coupling member that connects the first down conductor and the second down conductor.
3 more elements
A method for protecting a carbon blade from damage, comprising:
- coupling a carbon skin and a plurality of down conductors to the carbon blade;
- applying a voltage to the carbon blade;
- maintaining a similar voltage between the plurality of down conductors to reduce or avoid flashover;
- and
- maintaining a current path through the plurality of down conductors if one of the down conductors is damaged.
