src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372587891/689265.jpg"></div><h2> 避雷針有什么用途 </h2> <p> <span style="font-size:16px;">避雷，實際上是引雷德作用原理：在雷雨天氣，高樓上空出現(xiàn)帶電云層時，迅雷針和高樓頂知部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，而靜電感應(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道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，避雷針與云層之版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．避雷針就可以權(quán)把云層上的電荷導(dǎo)人大地，使其不對高層建筑構(gòu)成危險，保證了它的安全。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452432724610/5832678.jpg"></div><h2> 避雷針的保護范圍是多少？ </h2> <p> <span style="display:none;"></span><span 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，一級保護是以30米為半徑、二級保護是45米為半百徑、三級保護是60米為半徑做弧的保護范圍。計算方法避雷針的保護半徑與高度（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為被保護物的高度一般來說，避雷針越高，保護范圍就越大，保護效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟答性，避雷針大多建設(shè)在35米-45米之間。</span> </p><h2> 避雷針的作用是什么 </h2> <p> <span style="font-size:16px;">避雷針，又名防雷針、接閃桿，是用來保護建筑物、高大樹木等避免雷擊的裝置。避雷針由接閃器、接地引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長度為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。當(dāng)雷云對地放電通道發(fā)展到臨近地面時，由于避雷針前列突出地面并有良好接地，在針尖附近的電場強度提高，聚積相反極性的電荷，引導(dǎo)放電。進而防止建筑物或儀器蓄積過多電荷而遭受雷擊。一般來講，雷電并不會直接擊中避雷針，而避雷針本身如果被閃電擊中也有著融化及的危險。避雷針具有一定的保護作用.</span>

style="font-size:16px;">1.避雷針，又名防雷針、接閃桿，是用來保百護建筑物、高大樹木等避免雷擊的裝置。在被保護物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)度線與埋在地下的泄流地網(wǎng)連接起來。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個防雷類別需要的避問雷針高度規(guī)格都不一樣。 2.當(dāng)雷云放電接近地面時它使地面電場答發(fā)生畸變。在避雷針的頂端，形成局部電場集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針放電，專再通過接地引下線屬和接地裝置將雷電流引入大地，從而使被保護物體免遭雷擊。湖北乾元上風(fēng)電氣工程有限公司堅持“安全為先、服務(wù)為先、信譽為先”的經(jīng)營宗旨，并以“質(zhì)量至上、注重實效”的原則貫穿于各項工程的設(shè)計和施工。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、科學(xué)施工，多方面、安全、合理、經(jīng)濟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工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報社會及廣大客戶的信任與厚愛。</span>

style="font-size:16px;">1、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,進行點焊,然后加以校正,焊上其他三塊脅板。將引下線焊接在底板上,清理藥皮刷防銹漆。 2、避雷針應(yīng)垂直安裝牢固。垂直度允許偏差為3/1000。 3、針體彎曲，安裝的垂直度超出允許偏差。應(yīng)將針體重新調(diào)直，符合要求后再安裝。 4、**避雷針及其接地裝置與道路或建筑物的出入口保護距離不符合規(guī)定。其距離應(yīng)大于3m，當(dāng)小于3m時，應(yīng)采取均壓措施或鋪設(shè)卵石或瀝青地。 5、選購時應(yīng)注意：**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等。 6、注意：避雷針如果沒接地將是個迎雷針，所以必須謹慎。</span>
