摘要：闪电产生的闪电电涌、闪电静电感应和闪电电感应不仅会影响城镇燃气装置的正常运
行，还会损害处理装置的管道和关键设备。为确保四川省境内城镇燃气管道的防雷安全，本文分析了城镇燃气在四川省境内所属区域的雷电活动特征，结合防雷工程特点，从直接雷击、感应雷击、雷电波入侵和反击等几个方面提出雷电防护措施。

Abstract :Sichuan Province is rich in gas reserves and the city gas becomes the preferred fuel for people's
living and production. With the development of the social economic growth, the requirement of clean energy resources such as the city gas increasing rapidly and the construction scale of city gas pipeline network increase gradually. The overvoltage, electrostatic field and the strong electromagnetic radiation generated by lightning will not only affect the stable operation of the city gas device but also do harm to the processing device and the key equipment. In order to ensure the lightning protection safety of the city gas pipeline network, this paper analyzes the lightning activity properties of the city gas network region in Sichuan province. We combine the characteristics of lightning protection project and propose protection measures from the aspects such as direct lightning strike, indirect lightning strike, lightning wave intrusion and lightning counterattack.
