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，鄂州工廠避雷針安裝廠家，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，鄂州工廠避雷針安裝廠家。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?？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，鄂州工廠避雷針安裝廠家。</span>

style="font-size:16px;">據(jù)中國的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個(gè)錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。

style="font-size:16px;">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。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。湖北乾元上風(fēng)電氣工程有限公司堅(jiān)持“安全為先、服務(wù)為先、信譽(yù)為先”的經(jīng)營宗旨，并以“質(zhì)量至上、注重實(shí)效”的原則貫穿于各項(xiàng)工程的設(shè)計(jì)和施工。我們以質(zhì)量的技術(shù)力量和良好的服務(wù)態(tài)度為您的防雷工程提供多方面的解決方案和技術(shù)支持，做到科學(xué)設(shè)計(jì)、科學(xué)施工，多方面、安全、合理、經(jīng)濟(jì)的做好各類防雷建筑物的雷電防御及設(shè)備和人身的安全防護(hù)工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報(bào)社會(huì)及廣大客戶的信任與厚愛。</span>

</h2> <p> <span 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，使電場強(qiáng)度增加到極限值的雷電云電場發(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并提前放電，將雷電電流通過自身的接地導(dǎo)體傳向地面，避免保護(hù)對(duì)象直接遭雷擊。參考資料來源：百度百科——避雷針</span>
