The invention discloses a lightning protection and grounding device for a prefabricated concrete tower, wherein the prefabricated concrete tower is formed by connecting a plurality of prefabricated concrete components to each other first, and the lightning protection and grounding device includes: a lightning receptor , installed on the outer surface of each precast concrete component, for receiving lightning; a conductive grid, arranged in each precast concrete component, for conducting electricity; conductive connectors, connecting the plurality of precast concrete components to each other The lightning receptor of one of the two adjacent precast concrete assemblies is electrically connected to the conductive grid of the other of the two precast concrete assemblies. The lightning protection and grounding device for a prefabricated concrete tower according to an exemplary embodiment of the present invention has good electrical conductivity, simple electrical connection, and can prevent side lightning.
Description
technical field [0001] The invention relates to a lightning protection and grounding device for a prefabricated concrete tower, more specifically, a lightning protection and grounding device for a prefabricated concrete tower with a simple structure and good grounding effect. Background technique [0002] As the power of wind turbines increases, the diameter of the impellers increases. Correspondingly, the height of the existing steel towers (hereinafter referred to as steel towers) becomes higher and higher, and the cross-sectional dimensions of the steel towers also increase. getting bigger. As a result, the manufacturing cost of the steel tower increases significantly, and the steel tower is difficult to transport due to its heavy weight. In order to solve the above problems, a concrete tower has been proposed which is cheap to manufacture and easy to transport. But such concrete towers require lightning protection systems to protect against lightning strikes. Patent P...
