- 摘要:
- 目前使用的天然气计量器具均采用了微电子技术,使得计量系统容易遭受雷电的危害。文章针对湖田计量站天然气计量系统遭受雷击破坏的情况,分析了问题产生的原因,根据天然气计量系统的特点,综合考虑多方面的影响因素,提出了整体设计、综合治理、系统实施原则和有效拦截、良好屏蔽、均衡连接、合理接地、堵截通道、全面防御的防雷技术方法。通过一系列整改措施的实施,计量系统得到了很好的保护,安全运行一年多未受到雷击的影响,能够在雷雨天气正常、稳定运行。
Based on the destructive case happened in the natural gas metering system of Hutian metering station, the reason of the accident was analyzed, then a set of complete protection measures of preventing lightning were provided, including integral design, comprehensive treatment, principle of system implementation, effective interception, excellent shielding, equilibrium connection, rational grounding and passage blocking. Through the implementation of a series of renovation measures, the metering system has been well protected and not been impacted by lightning for more than one year since it was put into operation.2007,3(3): 74-75,76 收稿日期：2006-6-19分类号：TM863作者简介：赵刚(1978-),男,四川广安人,助理工程师,2002年毕业于重庆工商大学测控技术及仪表专业,现从事长输管道天然气计量和技术管理工作。参考文献：
