LIGHTNING PROTECTION SYSTEM FOR WIND GENERATORS

摘要

The invention relates to a lightening transmission element (1) which is fixed to a hub (21) of a wind generator and which is formed by a first conductor bar (2) which is fixed to a second insulating bar (5). According to the invention a first end (4) of the lightning transmission element (1) is positioned opposite a metal strip (18) that is disposed at the root of each blade (10) of the wind generator at a first distance which enables a flashover of incident lightning at a point on a blade (10) of the wind generator, while a second end (3) thereof is positioned opposite a gutter (12) of a nacelle (13) of the wind generator at a second distance which enables a lightning flashover. The lightning is conveyed from the point on the blade (10) at which it is incident thereon to the earth through a series of conduction means including the lightning transmission elements (1), said means preventing the lightning from striking the sensitive parts of the wind generator.
