style="font-size:16px;">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(shuō)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。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，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。按我國(guó)統(tǒng)計(jì)的雷電流幅值約為300 kA，其對(duì)應(yīng)的雷擊高度為408 m。取雷擊定位高度為400m，可得出不同高度避雷針的保護(hù)區(qū)和散擊區(qū)的地表半徑見(jiàn)表1。我國(guó)舊式民房一般高度在10 m以下，避雷帶和避雷網(wǎng)的高度與房高相同，安裝的短針?lè)览灼涓叨葹?～2 m，它們引起的散擊現(xiàn)象不明顯；高聳建筑物和高架避雷針引雷招致雷擊率增高和存在散擊區(qū)。</span> </p><h2> 避雷針安裝的注意事項(xiàng) </h2> <p> <span style="font-size:16px;"> (1)接地體頂面埋設(shè)深度應(yīng)符合設(shè)計(jì)要求。當(dāng)無(wú)要求時(shí)，不應(yīng)小于0.6m。角鋼及鋼管接地體應(yīng)垂直配置。除接地體外，接地體引出線的垂直部分和接地裝置焊接部位應(yīng)防腐處理;在作防腐處理前，表面必須除銹并去掉焊接處殘留的焊藥。 (2)垂直接地體的間距不應(yīng)小于其長(zhǎng)度的3~5倍。水平接地體的間距應(yīng)符合設(shè)計(jì)規(guī)定。當(dāng)無(wú)設(shè)計(jì)規(guī)定時(shí)不宜小于5m。 (3)除環(huán)形接地體外，接地體埋設(shè)位置應(yīng)在距建筑物3m以外。距建筑物出入口或人行道也應(yīng)大于3m，如小于3m時(shí)，應(yīng)采用均壓帶做法或在接地裝置上面敷設(shè)50~90mm厚度的瀝青層，其寬度應(yīng)超過(guò)接地裝置2m。 (4)利用底板鋼筋或深基礎(chǔ)做接地體：按設(shè)計(jì)圖尺寸位置要求，標(biāo)好位置，將底板鋼盤搭接焊好，再將柱主筋(不少于2根)底部與底板筋搭接焊，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標(biāo)記，以便引出和檢查。 (5)利用柱形樁基及平臺(tái)鋼筋做接地體：按設(shè)計(jì)圖尺寸位置，找好樁基組數(shù)位置，把每組樁基四角鋼盤搭接封焊，再與柱主筋(不少于2根)焊好，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標(biāo)記，以便引出和檢查。</span>

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(shuō)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。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，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</span>

style="font-size:16px;">避雷針是保護(hù)建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個(gè)金屬棒，用金屬線與埋在地下的一塊金屬板連接起來(lái)，利用金屬棒的前列放電，使云層所帶的電和地上的電逐漸中和。唐代《炙轂子》一書在記載了這樣一件事：漢朝時(shí)柏梁殿遭到火災(zāi)，一位巫師建議，將一塊魚尾形狀的銅瓦放在層頂上，就可以主防止雷電所引起的天火。屋頂上所設(shè)置的魚尾開頭的瓦飾，實(shí)際上兼作避雷之用，可認(rèn)為是現(xiàn)代避雷針的雛形。而早在以前，中國(guó)已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國(guó)旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國(guó)新事》一書中記有：中國(guó)屋脊兩頭，都有一個(gè)仰起的**，龍口吐出曲折的金屬舌頭，伸向天空，舌根連結(jié)一根細(xì)的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時(shí)刻就大顯神通，若雷電擊中了屋宇，電流就會(huì)從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說(shuō)明，中國(guó)古代建筑上的如雷裝置，在大批量和結(jié)構(gòu)上已和現(xiàn)代避雷針基本相似。</span>
