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，隨州建筑物避雷針生產(chǎn)廠家。 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，隨州建筑物避雷針生產(chǎn)廠家，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，隨州建筑物避雷針生產(chǎn)廠家。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>

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)生很大的電勢差，形成很強(qiáng)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(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> </p><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>
