Publication number: 20240110547Abstract: The present invention provides a wind turbine comprising a lightning protection system for providing an electrical conduction path suitable for conducting lightning from the rotor to electrical ground. The lightning protection system comprises a shroud which is electrically coupled to a wind turbine bearing housing and a wind turbine hub and/or the front end of the main shaft. The shroud forms part of the electrical conduction path so to electrically couple a wind turbine rotor to the bearing housing via a short circuit path that bypasses the bearing arrangement.Type: ApplicationFiled: October 7, 2020Publication date: April 4, 2024Inventors: Nathan A. Brilliant, Anders Niels Hansen

Patent number: 9709039Abstract: A lightning current transfer unit (100) for a wind turbine, the lightning current transfer unit (100) comprising a first portion (20a) configured to be electrically coupled to an electrically conducting portion of a blade of a wind turbine electrically connected to a down conductor of the blade and a second portion (20b) configured to be electrically coupled to an electrically conducting portion of a nacelle of the wind turbine connected to a down conductor connected to earth. The first portion (20a) and the second portion (20b) are both independently movable to maintain electrical coupling to the electrically conducting portion of the blade and nacelle respectively. A lightning current transfer portion (104) is provided that comprises a spark gap (106) formed between an electrical connection (108) to the first portion (20a) and an electrical connection (110) to the second portion (20b). The electrical connections (108, 110) are moveable with their respective first or second portion (20a, 20b).Type: GrantFiled: June 6, 2013Date of Patent: July 18, 2017Assignee: Vestas Wind Systems A/SInventors: Claus Gron Lyngby, Kent Bach Lønbæk, Anders Niels Hansen
