Abstract
A wind turbine blade having a blade shell with a lightning protection system. The lightning protection system has a first metal layer at an outer surface of the blade shell and a second metal layer at the outer surface of the blade shell and stacked on the first metal layer to form intimate electrical contact with the first metal layer at a multiple-thickness region.
Claims17
A wind turbine blade having a blade shell with a lightning protection system;
- the lightning protection system comprising:
- a first metal layer at an outer surface of the blade shell;
- and
- a second metal layer at the outer surface of the blade shell and stacked on the first metal layer to form intimate electrical contact with the first metal layer at a multiple-thickness region;
- and
- wherein the multiple-thickness region has a width of at least 200 mm and a length of at least 200 mm.
A wind turbine blade having a blade shell with a lightning protection system;
- the lightning protection system comprising:
- a first metal layer at an outer surface of the blade shell;
- and
- a second metal layer at the outer surface of the blade shell and stacked on the first metal layer to form intimate electrical contact with the first metal layer at a multiple-thickness region;
- and
- an electrical component,
- wherein the first and second metal layers are electrically connected to the electrical component by an electrically conductive pin that extends through the multiple-thickness region.
A method of manufacturing a wind turbine blade having a blade shell, comprising:
- laying a first metal layer of a lightning protection system of the blade shell into a blade mould;
- laying a second metal layer of the lightning protection system into the blade mould so that the second metal layer is stacked on the first metal layer to form a multiple-thickness region having a width of at least 200 mm and a length of at least 200 mm.
