Problems solved by technology

Because the yellow-green wire is connected to the frame of the solar panel by bolts, the bolts need to be fastened with a certain force to scratch the oxide film of the aluminum alloy frame. If there is no scratch, there will be no electrical conduction. Lightning ground connections are ineffective

Abstract

The invention discloses a grounding conducting structure of solar cell panels. The grounding conducting structure comprises a crossbeam of steel structure, and the solar cell panels and conductive pads arranged on the crossbeam, wherein the conductive pads are arranged on the crossbeam and connected with metal frames of the solar cell panels. The conductive pads are directly placed at the corresponding positions of the crossbeam of the steel structure, so that the metal frame of each solar cell panel is electrically connected with the steel crossbeam, grounding is very reliable, construction is convenient, the onsite workload and the amount of members are greatly reduced due to that no bolt connection exists, and the construction cost is reduced. Multiple points of each solar cell panel are electrically connected with the steel crossbeam, and thus, the lightning protection and grounding effects of the whole photovoltaic system can be ensured.

Description

technical field [0001] The invention relates to lightning protection and grounding technology for solar photovoltaic ground power stations, in particular to a photovoltaic grounding conductive structure. Before installing solar panels, grounding conductive sheets are directly placed on U-shaped steel beams, so that the aluminum frame of each solar panel All are in electrical conduction with the U-shaped steel beam, no bolt connection is required and the grounding conduction is reliable, which greatly reduces the on-site construction workload. Background technique [0002] Solar photovoltaic power stations generally occupy a relatively large area, have many solar panels, and repetitive work is common. According to the lightning protection and grounding requirements of photovoltaic power plants, it is required that the aluminum frame of each solar panel should adopt reliable equipotential electrical connection and grounding conduction. The conventional lightning protection an...
