1、做基礎(chǔ)時(shí)，安裝接地極： 2、結(jié)構(gòu)施工時(shí)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(shí)，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(shí)，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(shí)，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(gè)電容器，由于它較尖，即這個(gè)電容器的兩極板正對(duì)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，當(dāng)云層上電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成為導(dǎo)體，咸寧變電站避雷針廠家哪家好。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，避雷針就可以把云層上的電荷導(dǎo)入大地，咸寧變電站避雷針廠家哪家好，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全，咸寧變電站避雷針廠家哪家好。</span>

style="font-size:16px;">一般都認(rèn)為發(fā)明避雷針的人是18世紀(jì)的羅蒙諾索夫和富蘭克林。其實(shí)，早認(rèn)識(shí)避雷術(shù)的還是在我國(guó)。公元1688年，法國(guó)旅行家卡勃里歐列·戴馬甘蘭在游歷中國(guó)后，寫了一本《中國(guó)新事》的書，書中寫道：“……，中國(guó)屋宇的屋脊兩頭，都有一個(gè)仰起的**，龍口吐出曲折的金屬舌頭，伸上天空，舌根連接著一根根細(xì)的鐵絲，直通地下。這樣奇妙的裝置在發(fā)生雷電的時(shí)候就大顯神通，若雷電擊中了屋宇，電流就會(huì)從龍舌沿線下行地底，起不了絲毫破壞作用?！睆倪@里看來，我國(guó)對(duì)避雷針的應(yīng)用，比富蘭克林作的雷電實(shí)驗(yàn)要早兩個(gè)世紀(jì)以上。我國(guó)科學(xué)家經(jīng)過科學(xué)論證，證實(shí)遠(yuǎn)在三國(guó)和南北朝時(shí)代的建筑物就有了“避雷室”裝置。有關(guān)**還認(rèn)為：現(xiàn)在的廣西真武閣四柱不落地，德慶縣文廟四柱不頂天，都是古代建筑師為了使廳堂有人的地方避開雷擊，消除電學(xué)上稱為“跨步電壓”的危險(xiǎn)而設(shè)計(jì)的。</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(shí)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(duì)象免遭雷擊。現(xiàn)代避雷針是美國(guó)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(gè)雷雨天，冒著被雷擊的危險(xiǎn)，和他的兒子一起，做了一個(gè)歷史上非常的雷電實(shí)驗(yàn)。他將一個(gè)系著長(zhǎng)長(zhǎng)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(shí)，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(yàn)非常成功，讓富蘭克林充分認(rèn)識(shí)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> </p><h2> 安裝避雷針需要注意的事項(xiàng) </h2> <p> <span style="font-size:16px;">（一）安裝避雷針時(shí)需要注意：（1）建筑物頂部的避雷針必須與頂部的其他金屬物體連成一個(gè)整體的電氣通路。（2）不得在避雷針構(gòu)架上架設(shè)低電壓線路或通訊線路。（二）安裝避雷帶和避雷網(wǎng)時(shí)需要注意： 1.明裝避雷帶（網(wǎng)）（1）在屋面混凝土支座上的安裝避雷帶（網(wǎng)）的支座既可以在施工過程中現(xiàn)場(chǎng)澆制，也可以預(yù)制再砌牢。（2）在女兒墻上的安裝沿女兒墻安裝時(shí)，要使用支架固定，盡量隨結(jié)構(gòu)施工預(yù)埋支架。若條件受到限制，在墻體施工時(shí)需預(yù)留不小于100mmx 100mmx 100mm的孔洞，且洞口的大小里外一致。直線段支架的水平間距應(yīng)為1-1.5m，垂直間距應(yīng)為1.5-2m，且支架間距應(yīng)該平均分布。女兒墻上設(shè)置的支架應(yīng)該與墻頂面垂直。 (3)在屋脊或檐口支座、支架上的安裝需要使用混凝土支座或支架固定?，F(xiàn)場(chǎng)澆制支座的時(shí)候，首先把脊瓦敲去一角，使支座與脊瓦內(nèi)的砂漿連成一體；固定支架時(shí)，用電鉆將脊瓦鉆孔，再將支架插入孔內(nèi)，用水泥砂漿填塞牢固。支座和支架的水平間距為1-1.5m，轉(zhuǎn)彎處為0.25m-0.5m。</span>

style="font-size:16px;">在房屋處豎一金屬棒，棒下端連一條足夠粗的銅線，銅線下端連一塊金屬板埋入地下深處潮濕處。金屬棒的上端須是一個(gè)尖頭或分叉為幾個(gè)尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時(shí)。避雷針的前列因靜電感應(yīng)就集中了異種電荷，發(fā)生前列放電，與云內(nèi)的電相中和，避免發(fā)生激烈的雷電、這就是避雷針能避雷的一方面。但這種作用頗慢，如果云中積電很快，或一塊帶有大量電荷的云突然飛來，有時(shí)來不及按上述方式中和，于是有強(qiáng)烈的放電，加雷電仍會(huì)發(fā)生。但這時(shí)由于避雷針高過周圍物體，它的前列又集中了與云中電異號(hào)的電荷，如果雷電是在云和地面物之間發(fā)生，放電電流主要通過避雷針流入大地，因此，不會(huì)打在房屋或附近人的身上，只會(huì)打在避雷針上了。由此可見，避雷針的前列放電作用會(huì)減少地面物與云之間打雷的可能性；到了不可避免時(shí)，它自己就負(fù)擔(dān)了雷的打擊，房屋與人得到了安全。由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，斷口以上的一段就成為一個(gè)隔離的導(dǎo)電系統(tǒng)。</span>
