Title:
WIND POWER GENERATION FACILITY, LIGHTNING SURGE ABSORPTION DEVICE AND LIGHTNING SURGE ABSORPTION METHOD
Document Type and Number:
Japanese Patent JP2022047911
Kind Code:
A
Abstract:
To provide a wind power generation facility capable of reducing damage due to lightning strikes causing a lightning current as an impulse signal.SOLUTION: A wind power generation facility 1 includes: an erected support column 5; a plurality of blades 7 rotatably fitted to the support column 5; and a hub H fitted to a rotating shaft of the blades. In the wind power generation facility, impedance lines 8 are provided from the blades 7 over the hub H. A ground line 11 connected to the impedance lines 8 is provided in the hub H. The impedance lines 8 convert part of discharge energy of lightning strikes using the blades 7 as receptors into thermal energy.SELECTED DRAWING: Figure 3
