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)的地表半徑見表1。我國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，安裝的短針防雷其高度為1～2 m，恩施橋梁避雷針制作，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)，恩施橋梁避雷針制作。</span> 避雷針安裝廠家，恩施橋梁避雷針制作，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！恩施橋梁避雷針制作</p><div style="width:100%;text-align:

style="font-size:16px;">汽車不安裝避雷針，但車殼是金屬的，因屏蔽作用，就算閃電擊中汽車，也不會(huì)傷人，因此，車廂是躲避雷擊的理想地方。汽車的輪胎絕緣性能相當(dāng)好，雷電擊到汽車帶電，但電流傳不到地下形不成回路，不會(huì)對(duì)人和汽車造成危害。汽車的輪胎外帶有水或其它導(dǎo)電性物質(zhì)，有的帶有防靜電接地線。雷電擊到汽車帶電，電流有從金屬表面流動(dòng)的特性，不會(huì)對(duì)人產(chǎn)生危害。電流就通過汽車表面?zhèn)鞯綆в兴蚱渌鼘?dǎo)電性物質(zhì)的輪胎，帶有防靜電接地線傳到地下形成回路，不會(huì)對(duì)人和汽車造成危害。</span>

找直、找正后 , 進(jìn)行點(diǎn)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(shí)應(yīng)在建筑物首層起每三層設(shè)均壓環(huán)一圈。可將結(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> </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> 防雷避雷針，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良！</p><div

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。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>
