style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應(yīng)雷電和綜合性防雷電。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，仙桃建筑物避雷針、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)放電。避雷針在強電場作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電；兩者會合形成雷電通路，隨之瀉入大地，達到避雷效果。實際上，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，仙桃建筑物避雷針，避免保護對象直接遭雷擊，仙桃建筑物避雷針。</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> 荊州塔頂避雷針廠家哪家好避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，歡迎您來點電咨詢！</p><div style="width:100%;text-align:

在雷雨天氣，高樓上空出現(xiàn)帶電云層時，迅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，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)人大地，使其不對高層建筑構(gòu)成危險，保證了它的安全。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。 </p><h2> 避雷針一般多長. </h2> <p> <span style="font-size:16px;">用什么原理才不會被雷擊中避雷針從原理百上講，不是避雷，而是引雷，是引雷針。正是因為它比被保護物高，雷電流通過較高的避雷針入地，釋放較高的雷電壓，才使比避雷針低的建筑物或設(shè)度備不會被雷擊中，從而保護設(shè)備或建筑物的安全。知一般來說，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)濟性，避雷針大多建設(shè)在35米-45米之間。道用幾根避雷針，要看需要保護多大的范圍，如果需要保護的范圍較大，則專需要的避雷針數(shù)量就多，需要保護的范圍屬較小，則需要的避雷針數(shù)量就少，甚至1根就夠了。具體安裝數(shù)量，要通過計算及繪制避雷針保護范圍圖來確定。</span>

style="font-size:16px;">安裝避雷針必須遵守中華人民國家標(biāo)準(zhǔn)（GB50057—94）《建筑物防雷設(shè)計規(guī)范》，具體施工必須嚴(yán)格遵循國家標(biāo)準(zhǔn)（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗收規(guī)范，雷雨日不可進行避雷針的安裝和檢測。 ① 定貨時請告知您所選用的避雷針（塔）桿的技術(shù)參數(shù)，以便廠方給您選配更規(guī)范的互連過渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當(dāng)其厚度不小于4mm時，可作避雷針的引下線。筒體底部應(yīng)有兩處與接地體對稱連接。 ③ 建筑物L(fēng)的防雷設(shè)施采用多根引下線時，宜在各引下線距地面的1.5～1.8m處設(shè)置斷接卡，斷接卡應(yīng)加絕緣保護措施。容 ④ 避雷針與引下線之間的連接應(yīng)采用焊接。 ⑤ 避雷針其接地裝置，應(yīng)采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥ 安裝時請勿觸摸主接閃前列、主動放電前列。 ⑦ 產(chǎn)品設(shè)計使用壽命20年。</span> 避雷針安裝價格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！荊州塔頂避雷針廠家哪家好</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！仙桃建筑物避雷針</p><h2> 什么是雷電現(xiàn)象？ </h2> <p> <span style="font-size:16px;">所謂雷電現(xiàn)象，就是空中云層積累的電荷達到頗大數(shù)量時，它與附近的帶電云層或物體間產(chǎn)生很大的電勢差，形成很強的電場，兩部分異性電荷突破周圍空氣的阻礙去中和，發(fā)生強烈放電，這時在電通過的路徑上發(fā)出聲和光，就是雷電。雷電通常發(fā)生在不同的云塊之間，或云的下部與地面物之間。我們要避免的只是云和地或地上物之間的雷電。如果這塊云的上部帶正電，下部帶負電，則地面上感應(yīng)出來的電是正電，此時地面上的凸出物（房屋、樹或人體）就有可能與云中電荷發(fā)生放電現(xiàn)象，遭到雷擊的災(zāi)禍</span>
