style="font-size:16px;">雷雨天氣，高樓上空出現(xiàn)帶電云層時，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，導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入大地，使其不對高層建筑構(gòu)成危險，保證了它的安全。按我國統(tǒng)計的雷電流幅值約為300 kA，其對應(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>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452432724610/5832678.jpg"></div><h2> 避雷針是什么樣子？ </h2> <p> <span style="font-size:16px;">避雷針是保護建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個金屬棒，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，實際上兼作避雷之用，可認為是現(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)一根細的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時刻就大顯神通，若雷電擊中了屋宇，電流就會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> </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>
