Wind turbine, has maintenance supervising device forming sections of maintenance circuits with lightning stream diverting device, during maintenance of diverting device, where supervising device is permanent component of turbine

摘要

The turbine has a receptor (70-72) arranged in housing for a striking lightning and a maintenance stream supervising device (81) connected with a lightning stream diverting device (80) in the receptor. The supervising device forms sections of maintenance circuits with the diverting device, during maintenance of the diverting device. The supervising device is a permanent component of the turbine. The supervising and diverting devices are connected with an earthing device, during the operation of the turbine. The supervising device extends to a rotor blade root. An independent claim is also included for a method for maintaining a lightning stream diverting device.
