AI Technical Summary
Existing lightning protection devices lack voltage equalization structures, resulting in uneven distribution of lightning current, excessively high local voltage, damage to devices and electrical equipment, and unstable installation, making them prone to tilting or collapsing.
The system employs an equalizing ring structure, a two-stage surge arrester design, and an optimized mounting base. The equalizing ring evenly distributes the lightning current, enhancing installation stability and insulation performance. A grounding device is used to introduce the current into the earth, and an annular raised edge is provided on the surface of the surge arrester to increase the creepage distance.
It achieves uniform distribution of lightning current, improves the protective performance and service life of lightning protection devices, enhances installation stability and insulation performance, and reduces the risk of equipment damage.
