Abstract
The invention provides a blade lightning arrester mounting method, a blade and a wind generating set. The blade lightning arrester mounting method involves a vacuum pouring forming suction surface housing and / or pressure surface housing, wherein at least one of the lightning arrester, a lightning arrester tool and a lightning arrester mounting seat is embedded into the suction surface housing and / or the pressure surface housing; a storing hole for storing the lightning arrester is formed in the lightning arrester mounting seat; lightning protection plates are mounted on the suction surface housing and / or the pressure surface housing; the suction surface housing and the pressure surface housing are subjected to die closing, and the lightning arrester or the lightning arrester tool is connected with a corresponding lightning protection plate, or the storing hole in the lightning arrester mounting seat is corresponding to the corresponding lightning protection plate; then the lightning arrester tool is taken out, and the lightning arrester is assembled; and / or the lightning arrester is mounted in the lightning arrester mounting seat. With the adoption of the blade lightning arrester mounting method, a blade can be prevented from being damaged in last period, and thus the blade reliability can be improved.
Description
technical field [0001] The invention relates to the field of clean energy equipment, in particular to a blade lightning receptor installation method, a blade and a wind power generating set. Background technique [0002] At present, there are two methods of installing lightning receptors in the blade manufacturing process. The first is the full perforated installation, that is, the air receptors on the suction side of the blade (SS side, the leeward side of the blade) and the pressure side (PS side, the windward side of the blade, facing the direction of the wind) are all punched The method is connected with the lightning protection copper plate inside the blade. The installation method of punching holes is suitable for aluminum air-termination devices with a small air-termination area, and the diameter is about 20mm. [0003] This solution needs to drill holes on the surface of the blade to cause damage to the surface of the blade. When drilling, because the workers cann...
