Title:
LIGHTNING PROTECTION GROUNDING GRID
Document Type and Number:
WIPO Patent Application WO/2021/115092
Kind Code:
A1
Abstract:
A lightning protection grounding grid, comprising a first protection grounding grid unit and a second protection grounding grid unit. The first protection grounding grid unit comprises a first busbar (1), which is respectively connected to a first conductive wire (2), a second conductive wire (3) and a third conductive wire (4); the included angle between adjacent conductive wires of the first conductive wire (2), the second conductive wire (3) and the third conductive wire (4) is 60°, and a first grounding electrode (5) is connected to the first conductive wire (2), the second conductive wire (3) and the third conductive wire (4). The second protection grounding grid unit comprises a second busbar (6), a fourth conductive wire (7), a first grounding line (9) and a second grounding line (10); the second busbar (6) is connected to the first busbar (1) by means of an equipotential connector (11); the fourth conductive wire (7) is enclosed in a closed shape, the two ends thereof are respectively connected to the second busbar (6), and the fourth conductive wire (7) is further connected to a second grounding electrode (8); one end of the first grounding line (9) and one end of the second grounding line (10) are respectively connected to the second busbar (6). The two grounding grids do not interfere with each other at ordinary times. When a lightning current arrives, the equipotential connector (11) is turned on, and the two grounding grids are combined into one to facilitate discharge of the lightning current.
