Wind turbine lightning protection system and corresponding wind turbine rotor

摘要

A wind turbine rotor includes: at least one blade; a hub to which the at least one blade is attached; a spinner disposed so as to cover the hub, the spinner including an insulating material; a blade lightning-protection system provided for each of the at least one blade; and a spinner lightning-protection system provided for the spinner. The blade lightning-protection system includes: a blade receptor disposed on the at least one blade; and a current transmitting part electrically connected to the blade receptor for transmitting lightning current from the blade receptor to a grounding current path on a nacelle side. The spinner lightning-protection system includes: at least one spinner receptor disposed on the spinner; and a cable for electrically connecting the spinner receptor and the current transmitting part.
