油罐区综合防雷技术应用设计

Application Design of Comprehensive Lightning Surge Protection Technology in Oilcan Farm

针对危险系数较高的油罐区防雷难题,仅依靠传统接闪杆等直击雷防护系统已无法进行有效保护,提出了一种比较经济、合理、行之有效的防雷办法。首先对油罐区的防直击雷的方式进行分析,结合现有的防雷措施以及现场情况,对传统的独立接闪杆设置方法进行改进,应用接闪杆、避雷线相互结合的方式进行油罐区的有效防雷;然后在此基础上对仪表控制系统进行科学设计,有效防护。该综合防雷技术已成功应用于工程实践。

For the lightning surge protection of oilcan farm with high risk coefficient, it is not enough for protection with traditional lightning surge protection system of lightning rod. An economic, reasonable and effective lightning surge protection method is proposed. The direct lightning surge protection mode in the oilcan farm is evaluated, combining with current lightning surge protection measures and site situation, the setting mode for the lightning surge protection rod has been modified, and the combination mode of lightning protection with rod and line is efficient to the oilcan farm. Based on this new mode, the instrument control system has been designed scientifically, and is efficient for protection. The comprehensive lightning protection technology has been successfully applied in the engineering.
