1、裝置避雷針是避免雷擊的有效方法。在房屋高處豎一金屬棒，棒下端連一條足夠粗的銅線，銅線下端連一塊金屬板埋入地下深處潮濕處，鄂州機(jī)房避雷針檢測(cè)。金屬棒的上端須是一個(gè)尖頭或分叉為幾個(gè)尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時(shí)。 2、避雷針的前列因靜電感應(yīng)就集中了異種電荷，發(fā)生前列放電，與云內(nèi)的電相中和，避免發(fā)生激烈的雷電、這就是避雷針能避雷的一方面。但這種作用頗慢，如果云中積電很快，或一塊帶有大量電荷的云突然飛來，有時(shí)來不及按上述方式中和，于是有強(qiáng)烈的放電，鄂州機(jī)房避雷針檢測(cè)，加雷電仍會(huì)發(fā)生，鄂州機(jī)房避雷針檢測(cè)。</span>

style="font-size:16px;">一般都認(rèn)為發(fā)明避雷針的人是18世紀(jì)的羅蒙諾索夫和富蘭克林。其實(shí)，早認(rèn)識(shí)避雷術(shù)的還是在我國。公元1688年，法國旅行家卡勃里歐列·戴馬甘蘭在游歷中國后，寫了一本《中國新事》的書，書中寫道：“……，中國屋宇的屋脊兩頭，都有一個(gè)仰起的**，龍口吐出曲折的金屬舌頭，伸上天空，舌根連接著一根根細(xì)的鐵絲，直通地下。這樣奇妙的裝置在發(fā)生雷電的時(shí)候就大顯神通，若雷電擊中了屋宇，電流就會(huì)從龍舌沿線下行地底，起不了絲毫破壞作用?！睆倪@里看來，我國對(duì)避雷針的應(yīng)用，比富蘭克林作的雷電實(shí)驗(yàn)要早兩個(gè)世紀(jì)以上。我國科學(xué)家經(jīng)過科學(xué)論證，證實(shí)遠(yuǎn)在三國和南北朝時(shí)代的建筑物就有了“避雷室”裝置。有關(guān)**還認(rèn)為：現(xiàn)在的廣西真武閣四柱不落地，德慶縣文廟四柱不頂天，都是古代建筑師為了使廳堂有人的地方避開雷擊，消除電學(xué)上稱為“跨步電壓”的危險(xiǎn)而設(shè)計(jì)的。</span> 黃岡別墅避雷針制作防雷避雷針廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鄂州機(jī)房避雷針檢測(cè),避雷針" src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452426259766/8150720.jpg"></div><h2> 避雷針可以避雷的原理 </h2> <p> <span style="font-size:16px;">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。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。按我國統(tǒng)計(jì)的雷電流幅值約為300 kA，其對(duì)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> 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(dá)到頗大數(shù)量時(shí)，它與附近的帶電云層或物體間產(chǎn)生很大的電勢(shì)差，形成很強(qiáng)的電場(chǎng)，兩部分異性電荷突破周圍空氣的阻礙去中和，發(fā)生強(qiáng)烈放電，這時(shí)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(fù)電，則地面上感應(yīng)出來的電是正電，此時(shí)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> 避雷針安裝價(jià)格，湖北乾元上風(fēng)電氣供應(yīng)，歡迎您來點(diǎn)電咨詢！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鄂州機(jī)房避雷針檢測(cè),避雷針" src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452424707031/2495206.jpg"></div><h2> 避雷針是什么樣子？ </h2> <p> <span style="font-size:16px;">避雷針是保護(hù)建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個(gè)金屬棒，用金屬線與埋在地下的一塊金屬板連接起來，利用金屬棒的前列放電，使云層所帶的電和地上的電逐漸中和。唐代《炙轂子》一書在記載了這樣一件事：漢朝時(shí)柏梁殿遭到火災(zāi)，一位巫師建議，將一塊魚尾形狀的銅瓦放在層頂上，就可以主防止雷電所引起的天火。屋頂上所設(shè)置的魚尾開頭的瓦飾，實(shí)際上兼作避雷之用，可認(rèn)為是現(xiàn)代避雷針的雛形。而早在以前，中國已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國新事》一書中記有：中國屋脊兩頭，都有一個(gè)仰起的**，龍口吐出曲折的金屬舌頭，伸向天空，舌根連結(jié)一根細(xì)的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時(shí)刻就大顯神通，若雷電擊中了屋宇，電流就會(huì)從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說明，中國古代建筑上的如雷裝置，在大批量和結(jié)構(gòu)上已和現(xiàn)代避雷針基本相似。</span>

style="font-size:16px;">1、避雷針——直接接地。利用電荷前列放電現(xiàn)象不讓雷擊發(fā)生。避雷針和被保護(hù)物體是分開的，可以保護(hù)比較集中的重要物體。 2、避自雷器——間接接地。利用過電壓放電現(xiàn)象讓雷擊電壓通過避雷器進(jìn)入大地。避雷器和被保護(hù)物體是連接的，可以保護(hù)帶電物體，如輸電線路。避雷器工作原理：避雷器實(shí)百際上是一種非線性極好的電阻，在高電壓下電阻很小，在低電壓下電阻很高，作用類似于穩(wěn)壓度二極管。目前避雷器一般為氧化鋅避雷器，主要元件為問氧化鋅閥片。避雷器在電力系統(tǒng)中與被保護(hù)設(shè)備并聯(lián)，正常時(shí)泄漏電流很小，不影響系統(tǒng)運(yùn)行。當(dāng)系統(tǒng)有過電壓時(shí)（即超過正常運(yùn)行電壓的高電壓），避雷器即呈現(xiàn)低電阻泄放答能量，同時(shí)限制系統(tǒng)電壓的幅值，確保電氣設(shè)備的絕緣不被擊穿。</span>
