避雷針其實(shí)不“避雷” 通常情況下，城市建筑一般都會(huì)安裝避雷針，十堰信號(hào)避雷針加工廠家，許多人以為有了避雷針，就可以不用再操心“防雷”問題，事實(shí)上并非如此! (遭遇雷擊后的電視機(jī)殘骸) 雷電有直擊雷和感應(yīng)雷之分，十堰信號(hào)避雷針加工廠家。在家用電器的使用過程中，插座是一個(gè)防雷關(guān)口，要保護(hù)電器不被雷擊損害，就一定要使用具備防雷功能的專業(yè)插座。目前，市面上的一些防雷插座存在著較嚴(yán)重的質(zhì)量問題，如防雷技術(shù)不成熟;使用質(zhì)量低劣(三無產(chǎn)品:無廠家，十堰信號(hào)避雷針加工廠家、無參數(shù)、無證書)的防雷元器件;未經(jīng)專業(yè)防雷檢測(cè)機(jī)構(gòu)的檢驗(yàn)……等等，不僅防雷性能無法得到保證，甚至還存在更大的安全。</span>

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，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> 避雷針的建造要求有那些規(guī)范 </h2> <p> <span style="font-size:16px;">1、所有金屬部件必須鍍鋅，操作時(shí)注意保護(hù)鍍鋅層。 2、采用鍍鋅鋼管管制作針尖，管壁厚度不得小于3mm,針尖刷錫長度不得小于70mm。 3、避雷針應(yīng)垂直安裝牢固。垂直度允許偏差為3/1000。 4、焊接要求焊接應(yīng)采用搭接焊，其搭接長度必須符合下列規(guī)定： 5、扁鋼為其寬度的2倍(且至少3個(gè)棱邊焊接)。 6、圓鋼為其直徑的6倍。 7、圓鋼與扁鋼連接時(shí)，其長度為圓鋼直徑的6倍。 8、避雷針一般采用圓鋼或鋼管制成，其直徑不應(yīng)小于下列數(shù)值： 1）**避雷針一般采用直徑為19mm鍍鋅圓鋼。 2）屋面上的避雷針采用直徑25mm鍍鋅鋼管。 3）塔頂部避雷針采用直徑25mm或40mm的鍍鋅鋼管。 4）囪頂上避雷針采用直徑25mm鍍鋅圓鋼或直徑為40mm鍍鋅鋼管e避雷環(huán)用直徑12mm鍍鋅圓鋼或截面為100mm2鍍鋅扁鋼，其厚度應(yīng)為4mm。</span> 防雷避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良！</p><div

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>
