LIGHTNING TRANSMISSION DEVICE BETWEEN THE ROTOR AND THE NACELLE IN A WIND TURBINE

摘要

A lightning transmission device between the rotor and the nacelle in a wind turbine, which comprises: a first electricity conductor platen, where one of its ends is separated at a distance with respect to a metal strip located at a root of each blade; a second electricity conductor platen, where one of the ends is separated a distance with respect to a gutter element; an electrical conductor between the first and second platen; an electrical insulator coupled to said first and second platens; which is also coupled to the hub of the wind turbine; and a relative displacement unit between the first and second platen, the unit configured to ensure a predefined distance between the end of the first platen and the metal strip; and between the end of the second platen and the gutter element.

1. A lightning transmission device between the rotor and the nacelle in the wind turbine, configured to be installed in a wind turbine of blades turning with respect to a hub (3), where said wind turbine comprises additionally a gutter element (5), and the transmission device being characterised in that comprises:
a first electricity conductor platen (1), where one of its ends is separated at a distance from a metal strip (4) placed at a root of each blade; A second electricity conductor platen (2), where one of the ends is separated at a distance from the gutter element (5) of said wind turbine; electricity conductor means between the first and second platen (2); an electrical insulator (6) coupled to said first and second conductor platens (2), where said insulator (6) is coupled also to the hub (3) of said wind turbine, and relative displacement means between the first and second platen (2), said means configured to ensure a predefined distance between the end of the first platen (1) and the metal strip (4) located at the root of each blade; and between the end of the second platen (2) and the gutter element (5).
