style="font-size:16px;">在房屋處豎一金屬棒，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。金屬棒的上端須是一個尖頭或分叉為幾個尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時。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，有時來不及按上述方式中和，于是有強烈的放電，加雷電仍會發(fā)生。但這時由于避雷針高過周圍物體，它的前列又集中了與云中電異號的電荷，如果雷電是在云和地面物之間發(fā)生，天門小區(qū)避雷針廠家直銷，天門小區(qū)避雷針廠家直銷，放電電流主要通過避雷針流入大地，因此，不會打在房屋或附近人的身上，只會打在避雷針上了。由此可見，避雷針的前列放電作用會減少地面物與云之間打雷的可能性；到了不可避免時，它自己就負擔(dān)了雷的打擊，房屋與人得到了安全。由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，天門小區(qū)避雷針廠家直銷，斷口以上的一段就成為一個隔離的導(dǎo)電系統(tǒng)。</span>

style="font-size:16px;">一般都認為發(fā)明避雷針的人是18世紀的羅蒙諾索夫和富蘭克林。其實，早認識避雷術(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的鐵絲，直通地下。這樣奇妙的裝置在發(fā)生雷電的時候就大顯神通，若雷電擊中了屋宇，電流就會從龍舌沿線下行地底，起不了絲毫破壞作用?！睆倪@里看來，我國對避雷針的應(yīng)用，比富蘭克林作的雷電實驗要早兩個世紀以上。我國科學(xué)家經(jīng)過科學(xué)論證，證實遠在三國和南北朝時代的建筑物就有了“避雷室”裝置。有關(guān)**還認為：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”的危險而設(shè)計的。</span>

</p><h2> 避雷針為能避雷的原因 </h2> <p> 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。避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！</p><div
