The invention provides a fan
lightning protection system detection device and method.The fan
lightning protection system detection device comprises a
cantilever detection
assembly arranged on a fan
tower drum, the height position of the
cantilever detection
assembly is the position where the front end of a
fan blade rotates to be close to the bottom of the fan
tower drum, and a conductive
assembly is arranged at the front end of the
cantilever detection assembly; and the conductive assembly is used for contacting a
metal piece at the front end of the
fan blade and is connected with the detection unit, and the conduction state of the
lightning protection system is detected through the detection unit. According to the device, the conductive assembly is in contact with the
metal piece, and the conduction state between the conductive assembly and the
metal piece is detected through the detection unit, so that the conduction state of the fan
lightning protection system is judged. And a
soft magnet contact mode is adopted, so that fan blades are prevented from being abraded. According to the method, automatic detection of the
lightning protection system is realized, shutdown detection of the fan is not needed, detection personnel do not need to
climb on the fan
tower tube to carry out high-altitude operation, the
workload and risk of the detection personnel are reduced, and the continuous reliability of the
lightning protection system is further ensured.
