style="font-size:16px;">避雷針的工作原理就其本質(zhì)而言，避雷針不是避雷，而是利用其高聳空中的有利地來位，把雷電引向自身，承受雷擊。同時把雷電流泄入大地，起著保護(hù)其附源近比它矮的建筑物或設(shè)備免受雷擊的作用。簡單一點說，一級保護(hù)是以30米為半徑、二級保護(hù)是45米為半百徑、三級保護(hù)是60米為半徑做弧的保護(hù)范圍。計算方法避雷針的保護(hù)半徑與高度（h）有關(guān)，以及與所現(xiàn)的滾球半徑有關(guān)， D為滾球半徑（度閃擊距離）類建筑物為D＝30米第二類建筑物為D＝45米第三類建筑物為D＝60米保護(hù)范圍采用規(guī)范之計算公式： Rx=?{h(2hr-h)}-?{hx(2hr-hx)} 其中Rx為避雷針在距離地問面hx米處的保護(hù)半徑（米）； hr為滾球半徑,根據(jù)建筑物類別取值30、45、60； hx為被保護(hù)物的高度一般來說，避雷針越高，保護(hù)范圍就越大，保護(hù)效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟(jì)答性，避雷針大多建設(shè)在35米-45米之間。</span> 隨州塔頂避雷針安裝廠家避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！</p><div

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> </p><h2> 城市有避雷針 </h2> <p> <span style="font-size:16px;">家中是否也要安裝避雷針據(jù)調(diào)查，雷擊對電子電器設(shè)備的損壞始終高居雷電傷害榜*位，由雷電所引發(fā)的家用電器壽命降低、故障不斷、擊毀擊壞等情況越來越普遍，甚至還會造成人員傷亡，嚴(yán)重威脅到人們的財產(chǎn)和生命安全。因此，防止家電夏季被“雷”,其實遠(yuǎn)遠(yuǎn)比防暑更重要! 避雷針其實不“避雷” 通常情況下，城市建筑一般都會安裝避雷針，許多人以為有了避雷針，就可以不用再操心“防雷”問題，事實上并非如此! (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。在家用電器的使用過程中，插座是一個防雷關(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、無參數(shù)、無證書)的防雷元器件;未經(jīng)專業(yè)防雷檢測機(jī)構(gòu)的檢驗……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>

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>
