style="font-size:16px;">所謂雷電現(xiàn)象，就是空中云層積累的電荷達(dá)到頗大數(shù)量時，它與附近的帶電云層或物體間產(chǎn)生很大的電勢差，形成很強(qiáng)的電場，兩部分異性電荷突破周圍空氣的阻礙去中和，發(fā)生強(qiáng)烈放電，這時在電通過的路徑上發(fā)出聲和光，宜昌工廠避雷針安裝廠家，宜昌工廠避雷針安裝廠家，宜昌工廠避雷針安裝廠家，就是雷電。雷電通常發(fā)生在不同的云塊之間，或云的下部與地面物之間。我們要避免的只是云和地或地上物之間的雷電。如果這塊云的上部帶正電，下部帶負(fù)電，則地面上感應(yīng)出來的電是正電，此時地面上的凸出物（房屋、樹或人體）就有可能與云中電荷發(fā)生放電現(xiàn)象，遭到雷擊的災(zāi)禍</span> 避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！宜昌工廠避雷針安裝廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="宜昌工廠避雷針安裝廠家,避雷針"

style="font-size:16px;">雷雨天氣，高樓上空出現(xiàn)帶電云層時，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，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電容器，由于它較尖，即這個電容器的兩極板正對面積很小，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，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，使其不對高層建筑構(gòu)成危險，保證了它的安全。按我國統(tǒng)計的雷電流幅值約為300 kA，其對應(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，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>

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> 避雷針安裝注意事項 </h2> <p> <span style="font-size:16px;">安裝避雷針必須遵守中華人民國家標(biāo)準(zhǔn)（GB50057—94）《建筑物防雷設(shè)計規(guī)范》，具體施工必須嚴(yán)格遵循國家標(biāo)準(zhǔn)（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗收規(guī)范，雷雨日不可進(jìn)行避雷針的安裝和檢測。 ① 定貨時請告知您所選用的避雷針（塔）桿的技術(shù)參數(shù)，以便廠方給您選配更規(guī)范的互連過渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當(dāng)其厚度不小于4mm時，可作避雷針的引下線。筒體底部應(yīng)有兩處與接地體對稱連接。 ③ 建筑物L(fēng)的防雷設(shè)施采用多根引下線時，宜在各引下線距地面的1.5～1.8m處設(shè)置斷接卡，斷接卡應(yīng)加絕緣保護(hù)措施。容 ④ 避雷針與引下線之間的連接應(yīng)采用焊接。 ⑤ 避雷針其接地裝置，應(yīng)采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥ 安裝時請勿觸摸主接閃前列、主動放電前列。 ⑦ 產(chǎn)品設(shè)計使用壽命20年。</span> 防雷避雷針廠家，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="宜昌工廠避雷針安裝廠家,避雷針"

style="font-size:16px;"> 避雷針安裝要先將支座鋼板固定在預(yù)埋的地腳螺栓上 , 焊上一塊肋板 , 再將避雷針立起 , 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。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>
