Problems solved by technology

However, this patent is insufficient for the lightning protection at the rear of the nacelle, and does not consider the shielding protection and the equipotential connection of the metal parts on the nacelle. The metal mesh is embedded between the upper and lower layers of the nacelle cover, which has limitations.

Abstract

The invention provides a cabin cover of a wind generating set and the wind generating set with the cabin cover. The cabin cover comprises a metal mesh (10) laid on the cabin cover, wherein the metal mesh (10) on the cabin cover forms a Faraday cage. The Faraday cage is formed on the cabin cover, so that effective lightning receiving protection for discharge of lightning current can be realized, and grid type shield protection can be realized for a cabin.

Description

technical field [0001] The present invention relates to the technical field of wind power generating set equipment manufacturing, in particular, the invention relates to a nacelle cover and a wind generating set including the nacelle cover. Background technique [0002] The nacelle cover in a wind turbine is used to protect the metal parts of the wind turbine and other ancillary equipment from the external environment. Because of its high position and open space, the nacelle is most vulnerable to lightning strikes. [0003] At present, there are mainly two types of cabin cover materials, all-metal material and fiberglass material. The lightning protection effect of the all-metal nacelle cover is good, the thickness of the metal plate meets a certain requirement, and the lightning receiving effect and shielding effect are very good, but due to the weight problem, there are few practical applications. FRP nacelle covers are widely used in practical applications, but their li...
