| 摘 要： | 根据2009年6月江西省九江一次雷击事故现场的勘察结果,利用雷电监测数据和剩磁检测数据对雷电流大小进行了对比分析,认为造成雷击事故的可能原因有三方面,分别是电源SPD的保护级别不够、SPD的容量太小、接地引下线过长和截面积太小。最后,提出了相应的整改建议。

| Abstract: | According to the survey results of scene of a lightning strike accident in Jiujiang in June 2009,the lightning current was comparatively analyzed.There are three possible reasons for the lightning strike accident.The first is that the level of protection for SPD is not enough,the second is the capacity of SPD is too small,and the third is the length of grounding line is too long and the cross-sectional area is too small.Finally,the corresponding rectification is brought out. |
