| Popis: | In view of present status that current coal mine gas drainage station using independent lightning rod for direct lightning stroke protection, problems and hidden troubles of the status were analyzed, and a new type of lightning protection and grounding method was proposed. The method uses lightning protection framework and upper lightning protection network to replace lightning rod for the direct lightning stroke protection, uses sideward lightning shield wire against shielding failure for lightning shielding failure protection. Meanwhile, it introduces grounding device outside the station, so as to keep a certain safety distance from the grounding device to flammable and explosive materials inside the station. The actual application result shows the method has good lightning protection effect, and also has reference value for direct lightning protection and grounding of oil deport, gas station and other flammable and explosive place. |
