【摘要】：隨著科技的不斷進(jìn)步,人口的不斷增長(zhǎng),高層的辦公建筑和住宅越來(lái)越多。由于新型的高層建筑比傳統(tǒng)的建筑物更加智能化信息化,所以新型的智能建筑中一方面有大量的高精度的電子設(shè)備,另一方面信號(hào)回路增多,使智能建筑物系統(tǒng)更容易遭受雷電波的侵入,一旦雷電波侵入系統(tǒng)將會(huì)影響電子設(shè)備、電氣設(shè)備的正常運(yùn)行并且還會(huì)危及人生安全。因此智能建筑物的防雷顯得尤為重要。雷電的危害主要有由直擊雷引起的電效應(yīng)、熱效應(yīng)以及機(jī)械效應(yīng)對(duì)建筑物產(chǎn)生的危害,感應(yīng)雷產(chǎn)生的電磁感應(yīng)和靜電感應(yīng)等對(duì)弱電設(shè)備的危害,雷電波侵入的危害。針對(duì)以上的幾種雷電對(duì)建筑物的危害形式,我們采取外部防雷和內(nèi)部防雷相結(jié)合的綜合防雷措施設(shè)計(jì)智能建筑物的防雷系統(tǒng)。本文介紹了在欽州某大樓工程上的主要設(shè)計(jì)工作,依據(jù)建筑物對(duì)雷電防護(hù)的要求確定接閃器的設(shè)計(jì)方案。再用雷電產(chǎn)生的熱效應(yīng)和機(jī)械效應(yīng)原理中的公式來(lái)計(jì)算引下線遭受雷擊的影響,確定引下線的設(shè)計(jì)方案。為了防止電磁脈沖波對(duì)建筑物中的電子設(shè)備、信號(hào)線、電源線的影響,用屏蔽、等電位、接地以及安裝SPD保護(hù)電源系統(tǒng)和信號(hào)系統(tǒng),并通過(guò)選型的數(shù)據(jù)測(cè)算來(lái)驗(yàn)證方案的正確性。
[Abstract]:With the development of science and technology and the increase of population, there are more and more high-rise office buildings and houses. Because the new high-rise buildings are more intelligent and informational than the traditional ones, there are a large number of high-precision electronic devices in the new-type intelligent buildings on the one hand, and the number of signal loops on the other. The intelligent building system is more vulnerable to the intrusion of lightning waves. Once the lightning wave intrudes into the system, it will affect the electronic equipment, electrical equipment normal operation and also endanger the safety of life. Therefore, the lightning protection of intelligent buildings is particularly important. The harm of lightning is mainly caused by direct lightning, thermal effect and mechanical effect to the building, electromagnetic induction and electrostatic induction caused by induced lightning to the weak electric equipment, and the harm of lightning wave invasion. In view of the above several kinds of lightning damage to the building, we adopt the combination of external lightning protection and internal lightning protection to design the lightning protection system of intelligent building. In this paper, the main design work of a building in Qinzhou is introduced, and the design scheme of the flasher is determined according to the requirements of the building for lightning protection. Then the formula of thermal effect and mechanical effect caused by lightning is used to calculate the influence of lightning strike on the lead line, and the design scheme of the lead line is determined. To prevent the influence of electromagnetic pulse waves on electronic equipment, signal lines and power lines in buildings, shielding, equipotential, grounding and installation of SPD protection power and signal systems, The correctness of the scheme is verified by the data calculation of the selection.
