style="font-size:16px;">防直擊雷電的避雷裝置一般由三部分組成，即接閃器、引下線和接地體；接閃器又分為避雷針、避雷線、避雷帶、避雷網(wǎng)。以避雷針作為接閃器的防雷電原理是：避雷針通過(guò)導(dǎo)線接入地下，與地面形成等電位差，利用自身的高度，使電場(chǎng)強(qiáng)度增加到極限值的雷電云電場(chǎng)發(fā)生畸變，開始電離并下行先導(dǎo)屬放電；避雷針在強(qiáng)電場(chǎng)作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電。兩者會(huì)合形成雷電通路，隨之瀉入大地，達(dá)到避雷效果。實(shí)際上，避雷針是引雷針，可將周圍的雷電引來(lái)并提前放電，將雷電電流通過(guò)自身的接地導(dǎo)體傳向地面，避免保護(hù)對(duì)象直接遭雷擊。參考資料來(lái)源：百度百科——避雷針</span> </p><h2> 避雷針和避雷帶有什么區(qū)別？ </h2> <p> <span style="font-size:16px;"> ——★1避雷針是利用前列放電的原理，吸收雷電達(dá)到保護(hù)復(fù)作用。避雷針是保護(hù)某一片區(qū)域的，所以設(shè)置高度很高（具體高度，需要根據(jù)保護(hù)面積作復(fù)雜的計(jì)算），并且要有很高的強(qiáng)度要求，可以很好的吸收【直擊雷】的放電。 ——★2、建筑物避雷帶的避雷原理同避雷針相同，但是： ①、保護(hù)目的為建筑物自己，因此不制需要特別的高度等質(zhì)量要求； ②、一般的建筑物遭受直擊雷的可能性極低（高層建筑除外），主要防止【感應(yīng)雷】對(duì)建筑物的損害，一百般避雷帶足以滿足要求。 ——★3、直擊雷與感應(yīng)雷的區(qū)別： ①、直擊雷就是雷電直接與地面物體放電，釋放能量； ②、距離帶電云彩較近的建筑物，會(huì)度積聚與帶電云彩相反極性的、相同數(shù)量的電荷，當(dāng)帶電云彩突然失去電荷（如云彩之間放電），積聚在建筑物上的電荷就失去吸引力而四處泄放，這就是感應(yīng)雷。對(duì)于避雷針的材料，有很多種</span> 避雷針價(jià)格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="隨州建筑物避雷針安裝廠家,避雷針"

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> 避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！湖北學(xué)校避雷針安裝廠家</p><p

style="font-size:16px;">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。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。 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(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)。 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(lái)，有時(shí)來(lái)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。</span>
