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金屬棒，用金屬線與埋在地下的一塊金屬板連接起來，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，中國已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國新事》一書中記有：中國屋脊兩頭，都有一個仰起的**，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)生雷電的時刻就大顯神通，若雷電擊中了屋宇，電流就會從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說明，中國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>

style="font-size:16px;">垂直接地體的間距不應(yīng)小于其長度的3～5倍。水平接地體的間距應(yīng)符合設(shè)計規(guī)定。當(dāng)無設(shè)計規(guī)定時不宜小于5m。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，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)超過接地裝置2m。 1、裝置避雷針是避免雷擊的有效方法。在房屋高處豎一金屬棒，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尖頭或分叉為幾個尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時。 2、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，有時來不及按上述方式中和，于是有強(qiáng)烈的放電，加雷電仍會發(fā)生。</span> </p><h2> 避雷針的介紹<span style="display:none;"></span> </h2> <p> <span style="display:none;"></span><span style="font-size:16px;">1、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。在被保護(hù)物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)線與埋在地下的泄流地網(wǎng)連接起來。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個防雷類別需要的避雷針高度規(guī)格都不一樣。 2、當(dāng)雷云放電接近地面時它使地面電場發(fā)生畸變。在避雷針的頂端，形成局部電場集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針放電，再通過接地引下線和接地裝置將雷電流引入大地，從而使被保護(hù)物體免遭雷擊。 3、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隔離的導(dǎo)電系統(tǒng)。 4、當(dāng)云中有電荷時，這隔出的部分上部感應(yīng)出與云中電異號的電荷，而下部感應(yīng)出與云中電同號的電荷，如果上部和云中電起放電作用時，強(qiáng)大的放電電流只能通過建筑物放出大量熱量，于是引起雷擊。這樣不但不能避雷，反而還招來雷禍。為防意外，高大建筑物豎起幾條避雷針。另外，每一又避雷針只能保護(hù)一定的建筑面積。對于較大的建筑物也需要豎起幾條避雷針。</span>

找直、找正后 , 進(jìn)行點焊 , 然后加以校正 , 焊上其他三塊脅板。后面將引下線焊接在底板上 , 清理藥皮刷防銹漆。支座和支架，水平間距為1-1. 5m，轉(zhuǎn)彎處為0. 25m-0. 5m。引下線的上端與避雷帶（網(wǎng)）的交接處，應(yīng)彎曲成弧形再與避雷帶（網(wǎng)）并齊進(jìn)行搭接焊接。不同平面的避雷帶（網(wǎng)）應(yīng)至少有兩處互相連接，連接應(yīng)采用焊接。建筑物屋頂上的突出金屬物體，如旗桿、透氣管、鐵欄桿、爬梯、冷卻水塔、電視天線桿等，這些部位的金屬導(dǎo)體都必須與避雷帶（網(wǎng)）焊接成一體。避雷帶通過伸縮沉降縫的做法：應(yīng)將避雷帶向側(cè)面彎成半徑為100mm的弧形，且支持卡子中心距建筑物邊緣距離減至400mm，可以將避雷帶向下部彎曲。避雷針安裝時應(yīng)在建筑物首層起每三層設(shè)均壓環(huán)一圈?？蓪⒔Y(jié)構(gòu)圈梁鋼筋與柱內(nèi)充當(dāng)引下線的鋼筋進(jìn)行連接（綁扎或焊接）作為均壓環(huán)。沒有組合柱和圈梁的建筑物，應(yīng)每三層在建筑物外墻內(nèi)敷設(shè)一圈12mm鍍鋅圓鋼作為均壓環(huán)，并與防雷裝置的所有引下線連接。</span>

style="font-size:16px;">安裝避雷針時，應(yīng)注意以下事項： 1、在選擇**避雷針的裝設(shè)地點時，應(yīng)使避雷針及其接地裝置與配電裝置之間抄保持以下規(guī)定的距離：在地面上，由**避雷針到配電裝置的導(dǎo)電部分以及到變電所電氣設(shè)備和構(gòu)架地部分間的空間距離不應(yīng)小于6m,在地下，由**避襲雷針本身的接地裝置與變電所接地網(wǎng)間近的地中距離一般不小于3m。 2、**避雷針的接地電阻一般不宜超過10Ω。 3、為了防止雷擊避雷針時，雷電波由電線傳入室內(nèi)，危及人身安全，所以不得在避雷針構(gòu)架上架設(shè)電壓線路或通信線路。裝有避雷針的構(gòu)架上的照明燈電源線，必須采用直埋于地下的帶金屬保護(hù)層的電纜或穿入金屬管的導(dǎo)線。電纜保護(hù)層或金屬管必百須接地，埋地長度在10m以上，方可與配電裝置的接地網(wǎng)連接，貨與電源線度、低壓配電裝置相連接。</span>
