高层住宅楼防雷接地系统设计--毕业论文.doc

摘要 自古以来，雷电灾害就一直存在，根据统计，地球在任何时候平均有2000多个雷暴，平均闪电次数每秒100次，每次闪电强度高达10亿伏，破坏可想而知。随着科技的飞速发展，越来越多的高层建筑进入了大家的视野。最典型的是高层智能建筑，高层建筑容易吸引闪电，使它们自身和附近的建筑物被毁。此外，随着微电子技术的发展和广泛应用于各个领域，使受雷电灾害的物质发生了转移：由建筑物本身的雷电灾害转移到破坏室内电气设备、电子设备，以及在建筑物内居住的人的人身伤害事故上。同时防雷对象也从强电领域延伸到弱电领域。闪电产生的电磁脉冲对人身和财产的危害超过了直接雷击的危害，成为了当今雷击引发的主要危害。高层建筑内的各种电气设备的防雷接地技术先进与否直接关系到各种设备的安全可靠性和人身安全，由此我们可以看到建筑防雷接地的重要性。 关键词：防雷，接地，等电位 abstract Since ancient times, the thunder and lightning disasters have been there, according to statistics, the earth at any time on average there are more than 2 thousand thunderstorms, the average number of lightning per second, 100 times, each time the lightning intensity of up to 1 billion volts,damage can be imagined.With the rapid development of science and technology, more and more high-rise buildings into the field of vision. The most typical is the intelligent building, high-rise buildings to attract lightning, make their buildings and nearby buildings were destroyed. In addition, with the development of microelectronics technology and widely used in various fields, the lightning disaster material transfer the lightning of the building itself to destroy indoor electrical equipment, electronic equipment, and living within the building of personal injury accidents. At the same time, also from a strong field of lightning protection object extends to the weak electric field. The generation of lightning electromagnetic pulse harm to people and property than the direct lightning The harm, has become a major hazard caused by lightning. The lightning protection of electrical equipment in high-rise buildings of the grounding technology and not directly related to the safety and reliability of the equipment and personal safety, so we can see the importance of building lightning protection and grounding. Key words: lightning protection, grounding, and other potential 目录 绪论 1 1.雷击带来的危害 2 1.1闪电的主要危害有四种： 2 1.1.1直击雷 2 1.1.2雷电波入侵 2 1.1.3诱发过电压 2 1.1.4地电位反击 2 2.综合防雷系统设计 5 2.1综合防雷接地设计六大要素： 5 2.1
