4、扁鋼為其寬度的2倍(且至少3個(gè)棱邊焊接)。 5、圓鋼為其直徑的6倍。 6、圓鋼與扁鋼連接時(shí)，其長(zhǎng)度為圓鋼直徑的6倍。 7、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： **避雷針一般采用直徑為19mm鍍鋅圓鋼；屋面上的避雷針采用直徑25mm鍍鋅鋼管；水塔頂部避雷針采用直徑25mm或40mm的鍍鋅鋼管；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，武漢通信避雷針制作公司。</span>

15～20mm、長(zhǎng)度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。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百的電荷。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)云層上度電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成問為導(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。帶電的云，首先是從上往下運(yùn)行,在高處安避雷針，就首先將云中的電放答掉,以后到房子接觸云的時(shí)候，就基本沒有或只有少部分電而沒有危險(xiǎn)了</span>

style="font-size:16px;">避雷針是由美國科學(xué)家富蘭克林發(fā)明的富蘭克林在研究閃電與人工摩擦產(chǎn)生的電的一致性時(shí)，他就從兩者的類比中作出過這樣的推測(cè)：既然人工產(chǎn)生的電能被前列吸收，那么閃電也能被前列吸收。他由此設(shè)計(jì)了風(fēng)箏實(shí)驗(yàn)，而風(fēng)箏實(shí)驗(yàn)的成功反過來又證實(shí)了他的推測(cè)。他由此設(shè)想，若能在高物上安置一種前列裝置，就有可能把雷電引入地下。富蘭克林把一根數(shù)米長(zhǎng)的細(xì)鐵棒固定在高大建筑物的頂端，在鐵棒與建筑物之間用絕緣體隔開。然后用一根導(dǎo)線與鐵棒底端連接。再將導(dǎo)線引入地下。富蘭克林把這種避雷裝置稱為避雷針。經(jīng)過試用，果然能起避雷的作用。</span> </p><h2> 避雷針的工作原理 </h2> <p> <span 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(yíng)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>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372919922/6502836.jpg"></div><h2> 建筑物在多少高度必須安裝避雷針 </h2> <p> <span style="font-size:16px;">并不是規(guī)定有多少層需要裝避雷針，要看樓房是不是在避雷帶保護(hù)半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個(gè)51層的樓房上裝了避雷針，如果樓房在避雷針保護(hù)半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當(dāng)?shù)氐狞c(diǎn)，附近也有沒有裝避雷針，這樣也需要裝避雷針。避雷針的種類：直擊雷避雷針/特殊避雷針/提前預(yù)放電避雷針 1、直擊雷適用于石化倉庫、廣播電視、加油站、建筑大樓、信標(biāo)臺(tái)，通信基站、氣象臺(tái)、基地、雷達(dá)機(jī)房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達(dá)基站、信標(biāo)臺(tái)，通信基站、基地、雷達(dá)機(jī)房、銀行大樓、天文氣象臺(tái)等重要場(chǎng)所。 3、預(yù)放電當(dāng)避雷針截受雷擊時(shí)，由接閃體接閃，通過雷電波形處理裝置，利用外殼與中心接地桿之間有3mm間隙，構(gòu)成耦合電容，同時(shí)外殼通過一個(gè)電感線圈接地（中心接地桿）當(dāng)下行先導(dǎo)接近接閃器時(shí)，由于頻率極高，電感呈開路狀態(tài)，電容對(duì)高頻呈現(xiàn)短路特性。因此耦合電容作用下，接閃器表面電場(chǎng)強(qiáng)度迅速增加，直至觸發(fā)雪崩過程，從而能在頃刻間將雷電流泄放入地，以至有效的達(dá)到防雷害保安全的目的。</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)良值得推薦！荊門塔頂避雷針廠家</p><p style="text-indent:25px">防雷避雷針，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！武漢通信避雷針制作公司</p><h2> 安裝避雷針需要注意的事項(xiàng) </h2> <p> <span style="font-size:16px;">（一）安裝避雷針時(shí)需要注意：（1）建筑物頂部的避雷針必須與頂部的其他金屬物體連成一個(gè)整體的電氣通路。（2）不得在避雷針構(gòu)架上架設(shè)低電壓線路或通訊線路。（二）安裝避雷帶和避雷網(wǎng)時(shí)需要注意： 1.明裝避雷帶（網(wǎng)）（1）在屋面混凝土支座上的安裝避雷帶（網(wǎng)）的支座既可以在施工過程中現(xiàn)場(chǎng)澆制，也可以預(yù)制再砌牢。（2）在女兒墻上的安裝沿女兒墻安裝時(shí)，要使用支架固定，盡量隨結(jié)構(gòu)施工預(yù)埋支架。若條件受到限制，在墻體施工時(shí)需預(yù)留不小于100mmx 100mmx 100mm的孔洞，且洞口的大小里外一致。直線段支架的水平間距應(yīng)為1-1.5m，垂直間距應(yīng)為1.5-2m，且支架間距應(yīng)該平均分布。女兒墻上設(shè)置的支架應(yīng)該與墻頂面垂直。 (3)在屋脊或檐口支座、支架上的安裝需要使用混凝土支座或支架固定?，F(xiàn)場(chǎng)澆制支座的時(shí)候，首先把脊瓦敲去一角，使支座與脊瓦內(nèi)的砂漿連成一體；固定支架時(shí)，用電鉆將脊瓦鉆孔，再將支架插入孔內(nèi)，用水泥砂漿填塞牢固。支座和支架的水平間距為1-1.5m，轉(zhuǎn)彎處為0.25m-0.5m。</span>
