摘要
配电网架空线路经常发生雷击事故,严重影响配电线路的供电可靠性。通过对湛江麻章地区10kV配电线路进行现场调研,分析配电线路的雷害故障原因,针对线路雷害问题,提出了具体可靠的防护对策,能够保障线路供电可靠稳定运行,提高了配电线路的安全性和可靠性,并对线路防雷设计、线路改造,提供有价值的参考依据。
Lightning accidents often happen on distribution grid overhead lines, which seriously influences power supply reliability of distribution lines. Based on site investigation to 10 kV distribution lines of Mazhang area of Zhanjiang, this paper analyzed the cause of lightning disturbance of distribution lines. Aiming at the problems of circuit thunderstorm damage, this paper put forward concrete reliable protection countermeasures which could ensure reliable and stable operation of power supply lines, raising the safety and reliability of distribution lines. Lightning protection countermeasures provide valuable reference for lightning protection design and reform of distribution lines.
