| 摘 要： | 为了确定瓦斯抽放泵站放空管合理安置区域。在滚球半径法推算原理的基础上,利用几何知识,使用AutoCAD绘图软件绘制瓦斯抽放泵站放空管合理安置区域,而非传统方法的若干公式计算。AutoCAD绘图软件作图的方法避免了《GB 50057-2010建筑物防雷设计规范》附录D中传统方法繁琐的计算。确定瓦斯抽放泵站放空管合理安置区域作图法直观、简单、清晰、明了,简化了瓦斯抽放泵站防雷设计工作。为科学合理确定瓦斯抽放泵站放空管位置提供了依据。

| Abstract: | In order to determine vent pipe reasonable resettlement areas of the gas pump station. On the basis of the projection principle of the rolling sphere method, the use of geometric knowledge, the use of AutoCAD drawing software to draw gas drainage pumping station vent pipe reasonable resettlement areas,rather than the traditional methods of some formula. AutoCAD drawing software mapping method avoids the traditional method tedious calculated of "GB 50057-2010 Design code for protection of structures against lightning in Appendix D". Determine the gas pump station vent pipe reasonable resettlement areas mapping method is intuitive, simple, clear, straightforward, simplifying the gas pump station lightning protection design. Provide the basis for scientific and reasonable to determine the gas pump station vent pipe location. |
