Abstract
The invention relates to a wind turbine comprising a rotating part including a rotor with at least one blade and a wind turbine hub with at least one enclosure structure or similar wall structure, and a stationary part including a nacelle with at least one enclosure structure or similar wall structure. At least one of said parts comprises a conductive film layer of said enclosure structure with connection to a ground potential, where said film layer forms a shield enclosing said part or parts and protects against electromagnetic fields. The invention also relates to a method to manufacture said enclosure structure.
Claims26
A wind turbine comprising:
- a rotating part including a rotor with at least one blade and a wind turbine hub with at least one enclosure structure or similar wall structure,
- a stationary part including a nacelle with at least one enclosure structure or similar wall structure, wherein
- each of said rotating part enclosure structure and said stationary part enclosure structure comprises a conductive film layer with connection to a ground potential, where said conductive film layer forms a shield enclosing said rotating part enclosure structure and said stationary part enclosure structure and protects against electromagnetic fields.
A method for manufacturing a wind turbine comprising of the steps of:
- making a rotating part including a rotor with at least one blade and a wind turbine hub with at least one enclosure structure or similar wall structure,
- making a stationary part including a nacelle with at least one enclosure structure or similar wall structure,
- applying a conductive film layer to each of said rotating part enclosure structure and said stationary part enclosure structure with connection to a ground potential, where said conductive film layer forms a shield enclosing said rotating part enclosure structure and said stationary part enclosure structure and protects against electromagnetic fields.
