炼油化工企业现场自动化仪器仪表设备防雷技术初探

A Preliminary Study on Lightning Protection Technology for On-Site Automated Instrumentation Equipment in Oil Refining and Chemical Enterprises

随着我国炼油化工企业的飞速发展,行业自动化仪器仪表的使用越来越广泛,自动化仪表设备的检测精度及稳定性极易受到外界电磁干扰,尤其是雷电频发区域,雷电影响很容易使仪表发生损坏.结合工程实例,对炼油化工企业现场仪表受雷击形式以及防雷技术措施进行探讨.

With the rapid development of China's oil refining and chemical enterprises,the use of industry automation instrumentation is becoming more and more widespread,the detection accuracy and stability of automated instrumentation equipment is very susceptible to external electromagnetic interference,especially in lightning-frequent areas,the impact of lightning is very easy to make the instrumentation damage.In this paper,combined with engineering examples,the refining chemical enterprises on-site instrumentation by the form of lightning strikes and lightning technical measures to discuss.
