摘　　要：橇装式LNG汽车加气站作为新型加气站的一种,其一旦发生雷击并引发火灾或爆炸将造成不可估量的损失,因此橇装式LNG汽车加气站的防雷安全十分重要。在结合橇装式LNG汽车加气站所处环境及其系统特点,雷电对其破坏机理和途径,分析了造成雷电灾害因子。通过计算分析,运用ADBSGP现代综合防雷技术从防直击雷、防闪电感应、防雷击电磁脉冲等方面入手,提出了安装外部防雷装置、采用防雷等电位连接技术作为防闪电感应措施,采取屏蔽和安装SPD作为防雷击空间电磁场和闪电电涌侵入措施。As a new type filling station , if the LNG skid-mounted vehicle filling station is stroke by lightning prac-tion, it will cause serious accident .So it is very important to strengthen the lightning protection security work . Through analyzing the characteristics of environment and system of LNG skid -mounted vehicle filling station , as well as the damage mechanism and way by lightning , the factors of lightning disasters were analyzed .By applying ADB-SGP modern synthetical lighnting protection technology , and starting with the direct lightning flash protection , the lightning induction protection , the lightning electromagnetic impulse protection , it was proposed to take installing exterral lightning protection device and applying equipotenial connection technology as the lightning induction pro -tection measures , and take applying shield and installing SPD as the lightning electomagnetic field and lightning surging protection measures .
