Title:
PULL-DOWN CONDUCTOR INSTALLATION MECHANISM FOR WIND POWER GENERATOR
Document Type and Number:
Japanese Patent JP2011149412
Kind Code:
A
Abstract:

To provide a safe and sure lightning damage protecting means for a wind power generator.

The wind power generator has a blade and a nacelle on a tower erected on a ground. A projecting rod on the nacelle is connected to an earth part in the ground via a suspended pull-down conductor. In this case, a protecting pipe having an annular step part inside is provided in the tower while being supported by a supporting member, and a plurality of insulators fixed to the pull-down conductor are located on the annular step part in contact therewith and the outer faces of the insulators are located adjacent to the inner face of the protecting pipe. The pull-down conductor is provided somewhat longer than a distance between the insulators for absorbing the tensile force of the nacelle, when turned, on the pull-down conductor while giving complete electric insulation to the tower.
