Abstract
Provided is an electrical protection system allowing transferring to the ground static electricity accumulated onto the blades of a wind generator, and the lightning current when a lightning strikes onto at least one of the blades or at the rotor, including a first discharging unit configured for continuously discharging to the ground the static electricity accumulated onto the blades, and a second discharging unit configured for discharging to the ground the lightning current when a lightning strikes in at least one of the blades or at the rotor.
Claims21
An electrical protection system for wind turbines with blades rotating with respect to the hub of a nacelle, wherein the electrical protection system allows transferring to the ground static electricity accumulated at the blades and current from a lightning when a lightning strikes onto the blades or at the rotor, wherein the electrical protection system comprises:
- a first discharging unit configured for being in contact to some metallic part of the blade and continuously discharging to the ground, through the blade bearings or the metallic structure of the hub, the static electricity accumulated at the blades, and
- a second discharging unit configured for discharging to the ground the lightning current when there is a lightning strike event onto at least one of the blades or at the rotor.
