A new lightning protection system for vehicles

摘要

The paper introduces a new lightning protection system of vehicles running at a high speed. The lightning rod for direct lightning protection can reduce lightning interception probability to a level as low as possible so as to minimize damage of vehicles by direct lightning stroke. SPDs are provided for protection of corresponding power supply, signal, and antenna feed ports of equipments and systems installed inside vehicles. Equipotential bonding is adopted to prevent back flashover due to different earth potentials. The vehicles as well as their electronic equipments and systems inside can thus be effectively protected against lightning and their safety can be ensured. Finally, the paper introduces a quick-installation earthing electrode used specially for military vehicles requiring low earthing resistance when they stop at a military position.
