2、結(jié)構(gòu)施工時利用結(jié)構(gòu)內(nèi)鋼筋（或**型鋼）做引下線，與接地極連接，并預(yù)留與避雷帶的連接點(diǎn)； 3、裝修完成的同時，敷設(shè)避雷帶（或避雷針）。避雷針的原理：在雷雨天氣，高樓上空出現(xiàn)帶電云層時，避雷針和高樓頂部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，所以靜電感應(yīng)時，導(dǎo)體前列總是聚集了多的電荷。這樣，避雷針就聚集了大部分電荷。避雷針又與這些帶電云層形成了一個電容器，由于它較尖，即這個電容器的兩極板正對面積很小，電容也就很小，也就是說它所能容納的電荷很少。而它又聚集了大部分電荷，所以，湖北信號避雷針檢測，當(dāng)云層上電荷較多時，避雷針與云層之間的空氣就很容易被擊穿，成為導(dǎo)體。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，湖北信號避雷針檢測，避雷針就可以把云層上的電荷導(dǎo)入大地，使其不對高層建筑構(gòu)成危險，湖北信號避雷針檢測，保證了它的安全。</span>

style="font-size:16px;">用什么原理才不會被雷擊中避雷針從原理百上講，不是避雷，而是引雷，是引雷針。正是因為它比被保護(hù)物高，雷電流通過較高的避雷針入地，釋放較高的雷電壓，才使比避雷針低的建筑物或設(shè)度備不會被雷擊中，從而保護(hù)設(shè)備或建筑物的安全。知一般來說，避雷針越高，保護(hù)范圍就越大，保護(hù)效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟(jì)性，避雷針大多建設(shè)在35米-45米之間。道用幾根避雷針，要看需要保護(hù)多大的范圍，如果需要保護(hù)的范圍較大，則專需要的避雷針數(shù)量就多，需要保護(hù)的范圍屬較小，則需要的避雷針數(shù)量就少，甚至1根就夠了。具體安裝數(shù)量，要通過計算及繪制避雷針保護(hù)范圍圖來確定。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452432724610/5832678.jpg"></div><h2> 避雷針的作用是什么 </h2> <p> <span style="font-size:16px;">避雷針，又名防雷針、接閃桿，是用來保護(hù)建筑物、高大樹木等避免雷擊的裝置。避雷針由接閃器、接地引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。當(dāng)雷云對地放電通道發(fā)展到臨近地面時，由于避雷針前列突出地面并有良好接地，在針尖附近的電場強(qiáng)度提高，聚積相反極性的電荷，引導(dǎo)放電。進(jìn)而防止建筑物或儀器蓄積過多電荷而遭受雷擊。一般來講，雷電并不會直接擊中避雷針，而避雷針本身如果被閃電擊中也有著融化及的危險。避雷針具有一定的保護(hù)作用.</span> </p><h2> 避雷針是如何避電的？ </h2> <p> <span style="font-size:16px;">防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是大家通常所說的“避雷針”，它通過引下線和接地裝置與大地相連。避雷針高高聳立，高于被保護(hù)的所有物體，與雷云的距離近，所以，它易吸引雷電，雷電通過避雷針提供的放電通道泄放入地。這樣，雷擊雖然還是發(fā)生了，但總是擊向避雷針，而不是擊向要保護(hù)的物體，所以避雷針實際是引雷針。它將雷電吸引至自身，使雷電通過引下線至接地裝置而泄放到大地上，從而使保護(hù)對象免遭雷擊。現(xiàn)代避雷針是美國科學(xué)家富蘭克林發(fā)明的。富蘭克林認(rèn)為閃電是一種放電現(xiàn)象。為了證明這一點(diǎn)，他在1752年7月的一個雷雨天，冒著被雷擊的危險，和他的兒子一起，做了一個歷史上非常的雷電實驗。他將一個系著長長金屬導(dǎo)線的風(fēng)箏放飛進(jìn)雷雨云中，在金屬線末端拴了一串銅鑰匙。當(dāng)雷電發(fā)生時，富蘭克林手接近鑰匙，鑰匙上迸出一串電火花，手上還有麻木感。幸虧這次傳下來的閃電比較弱，富蘭克林沒有受傷。這次試驗非常成功，讓富蘭克林充分認(rèn)識了雷電的性質(zhì)，并由此發(fā)明了避雷針，首先在自己費(fèi)城的住宅安裝了避雷針。此后，避雷針便在世界上流行開來。</span>

style="font-size:16px;">防雷接地在我們的生活中是至關(guān)重要的，它直接關(guān)系到建筑物和我們的人身安全，湖北防雷公司在防雷接地上給予了很大的支持，很好的解決了防雷的問題。雷擊時會產(chǎn)生強(qiáng)大的電流，產(chǎn)生的能量能夠?qū)ㄖ镌斐蓢?yán)重的破壞，甚至威脅到人類的生命，所以施工人員在防雷接地施工的時候一定要非常謹(jǐn)慎，不能出現(xiàn)任何紕漏差錯，其施工質(zhì)量直接應(yīng)影響到建筑物的安全和使用壽命，所以選擇一個好的施工監(jiān)理是非常重要的。湖北乾元上風(fēng)電氣工程有限公司堅持“安全為先、服務(wù)為先、信譽(yù)為先”的經(jīng)營宗旨，并以“質(zhì)量至上、注重實效”的原則貫穿于各項工程的設(shè)計和施工。我們以質(zhì)量的技術(shù)力量和良好的服務(wù)態(tài)度為您的防雷工程提供多方面的解決方案和技術(shù)支持，做到科學(xué)設(shè)計、科學(xué)施工，多方面、安全、合理、經(jīng)濟(jì)的做好各類防雷建筑物的雷電防御及設(shè)備和人身的安全防護(hù)工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報社會及廣大客戶的信任與厚愛。</span>

style="font-size:16px;">并不是規(guī)定有多少層需要裝避雷針，要看樓房是不是在避雷帶保護(hù)半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個51層的樓房上裝了避雷針，如果樓房在避雷針保護(hù)半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當(dāng)?shù)氐狞c(diǎn)，附近也有沒有裝避雷針，這樣也需要裝避雷針。避雷針的種類：直擊雷避雷針/特殊避雷針/提前預(yù)放電避雷針 1、直擊雷適用于石化倉庫、廣播電視、加油站、建筑大樓、信標(biāo)臺，通信基站、氣象臺、基地、雷達(dá)機(jī)房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達(dá)基站、信標(biāo)臺，通信基站、基地、雷達(dá)機(jī)房、銀行大樓、天文氣象臺等重要場所。 3、預(yù)放電當(dāng)避雷針截受雷擊時，由接閃體接閃，通過雷電波形處理裝置，利用外殼與中心接地桿之間有3mm間隙，構(gòu)成耦合電容，同時外殼通過一個電感線圈接地（中心接地桿）當(dāng)下行先導(dǎo)接近接閃器時，由于頻率極高，電感呈開路狀態(tài)，電容對高頻呈現(xiàn)短路特性。因此耦合電容作用下，接閃器表面電場強(qiáng)度迅速增加，直至觸發(fā)雪崩過程，從而能在頃刻間將雷電流泄放入地，以至有效的達(dá)到防雷害保安全的目的。</span>
