摘　　要：大型浮顶储罐应特别注意防范密封圈雷击火灾。结合多次典型储罐火灾事故案例,分析储罐设计施工和运行维护中密封圈失效原因。分别从二次密封装置、设施电气连接、防雷接地检测等方面,阐述了国内储罐防雷技术现状及存在问题。介绍了储罐新型无油气密封装置、主动式氮气防护系统和雷电预警系统的设计理念和应用情况。分别从设计、施工、密封装置形式、储罐雷击火灾扑救和储罐安全管理模式等方面,提出了增强储罐预防雷击火灾风险的能力的措施和建议。For large-scale floating roof storage tank, special attention shall be paid to prevent lightning fire of sealing ring. Combined with several typical tank fire accidents, the reasons of seal ring failure in tank design, construction, operation and maintenance are analyzed. The present situation and existing problems of domestic storage tank lightning protection technology are expounded from the aspects of second sealing device, electrical connection of facilities, lightning protection and grounding detection, etc., respectively. The design concept and application of new oil & gas free sealing device, active nitrogen protection system and lightning early-warning system for storage tanks are introduced. From the aspects of design, construction, sealing device form, storage tank lightning firefighting and storage tank safety management mode, the measures and suggestions to enhance the ability of storage tank to prevent lightning fire risk are put forward.
