【摘要】：雷电作为自然界中一种无法避免的放电现象,主要通过雷击地面物体时产生的雷电流或引起的电磁感应对地面物体或人身造成损害或伤害。随着科技的高速发展,电气电子设备广泛应用于现代建筑物中成为建筑物密不可分的一部分,电气电子元器件的灵敏度也越来越高极易受到雷电的侵害,造成的直接、间接损失也越来越大。因此,为更好的避免和减少雷电对建筑物造成的危害,研究雷电对建筑物的灾害发生规律,进行建筑物雷电防护系统的设计和实施显得十分必要。建筑物的雷电防护问题是一项涉及多学科领域的系统化综合工程。目前,在国内外存在多种雷电防护理论及方法,但仍未统一,也未找到一种十分有效的方法;我国虽然颁布了相应的规范、规程并不断进行更新完善,但仍不能完全满足建筑物雷电防护设计与实施全部要求。本论文借鉴已有的研究成果,并结合自己的工程实践经验,对建筑物雷电防护系统主导因素进行了系统分析、归纳、总结,提出了更加规范化的设计、实施步骤和方法。本论文主要作了以下工作内容:第一、研究雷电产生过程的物理机理及其主要的三种表现形式,并对雷电产生的雷电流、电磁场的破坏机理进行了深入分析;在上述研究分析的基础上总结出建筑物雷电防护系统设计的主要主导因素。第二、在前述分析研究的基础上,总结出雷电防护措施基本准则和直击雷、感应雷、球形雷所应采取的雷电防护措施。第三、以工程设计、实施实例介绍了建筑物雷电防护系统的设计与实施,主要对建筑物概况、位置、气象等进行分析,并在分析的基础上得出建筑物雷电防护的必要性、防雷分类、系统防护等级,最后依据分析结果进行了具体的工程设计和实施。本课题的研究成果为建筑物雷电防护系统的设计实施提供了系统化、规范化的设计、实施步骤,具有一定的工程实用价值,能够带来一定的社会效益和经济效益。
[Abstract]:Lightning, as an unavoidable discharge phenomenon in nature, is mainly caused by lightning current or electromagnetic induction, which causes damage or injury to ground object or person. With the rapid development of science and technology, electrical and electronic devices are widely used in modern buildings as an inseparable part of the building. The sensitivity of electrical and electronic components is increasingly high and vulnerable to lightning damage. Indirect losses are also increasing. Therefore, in order to avoid and reduce the harm caused by lightning to buildings, it is necessary to study the regularity of lightning damage to buildings and design and implement the lightning protection system of buildings. The lightning protection of buildings is a systematic and comprehensive project involving multi-disciplinary fields. At present, there are many kinds of lightning protection theories and methods at home and abroad, but they have not been unified and a very effective method has not been found. However, it still can not meet all the requirements of design and implementation of lightning protection in buildings. This paper draws lessons from the existing research results and combines its own engineering practice experience to systematically analyze, summarize, and put forward more standardized design, implementation steps and methods for the main factors of building lightning protection system. The main contents of this thesis are as follows: first, the physical mechanism and three main forms of lightning generation are studied, and the lightning current and electromagnetic field damage mechanism are analyzed deeply. Based on the above research and analysis, the main factors of the design of lightning protection system for buildings are summarized. Secondly, on the basis of the above analysis, the basic principles of lightning protection measures and the lightning protection measures for direct strike, inductive and spherical lightning are summarized. Thirdly, the paper introduces the design and implementation of building lightning protection system with engineering design and implementation examples, mainly analyzes the general situation, location and meteorology of buildings, and concludes the necessity of building lightning protection on the basis of analysis. Lightning protection classification, system protection grade, and finally according to the analysis results of the specific engineering design and implementation. The research results of this subject provide systematic, standardized design and implementation steps for the design and implementation of building lightning protection system. It has certain engineering practical value and can bring certain social and economic benefits.
