Analysis and Rectification Plan of A Lightning Strike Accident in Anhui

本文根据安徽省某公司6月27日两次雷击事故的天气背景、现场勘查,结合该公司的防雷设施建设情况开展雷击事故分析。研究结果表明:该公司的防雷设施建构存在一定的防雷隐患,如静电地板和均压环未有可靠的接地、防雷设施未对全厂进行屏蔽、部分设备未与公共接地装置连接、高低压线路未分开铺设,并针对上述情况提出整改建议。通过此次案例分析能够进一步规范防雷安全。

Based on the weather background and site survey of two lightning strikes by an Anhui company on June27 th,combined with the company’s lightning protection facilities construction,this article carried out an analysis of lightning accidents.The research results show that there are certain lightning protection hidden dangers in the construction of lightning protection facilities of the company,such as the electrostatic floor and grading ring are not reliably grounded,the lightning protection facilities are not shielded for the whole plant,some equipment are not connected with public grounding devices,and high and low voltage lines are not laid separately.Rectification suggestions are put forward for the above situation.Through this case analysis,the lightning protection safety can be further standardized.
