style="font-size:16px;">防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是大家通常所說(shuō)的“避雷針”，它通過(guò)引下線和接地裝置與大地相連。避雷針高高聳立，高于被保護(hù)的所有物體，與雷云的距離近，所以，它易吸引雷電，雷電通過(guò)避雷針提供的放電通道泄放入地。這樣，雷擊雖然還是發(fā)生了，但總是擊向避雷針，而不是擊向要保護(hù)的物體，所以避雷針實(shí)際是引雷針。它將雷電吸引至自身，使雷電通過(guò)引下線至接地裝置而泄放到大地上，從而使保護(hù)對(duì)象免遭雷擊。現(xiàn)代避雷針是美國(guó)科學(xué)家富蘭克林發(fā)明的。富蘭克林認(rèn)為閃電是一種放電現(xiàn)象。為了證明這一點(diǎn)，他在1752年7月的一個(gè)雷雨天，冒著被雷擊的危險(xiǎn)，和他的兒子一起，做了一個(gè)歷史上非常的雷電實(shí)驗(yàn)。他將一個(gè)系著長(zhǎng)長(zhǎng)金屬導(dǎo)線的風(fēng)箏放飛進(jìn)雷雨云中，在金屬線末端拴了一串銅鑰匙。當(dāng)雷電發(fā)生時(shí)，富蘭克林手接近鑰匙，鑰匙上迸出一串電火花，手上還有麻木感。幸虧這次傳下來(lái)的閃電比較弱，富蘭克林沒(méi)有受傷。這次試驗(yàn)非常成功，讓富蘭克林充分認(rèn)識(shí)了雷電的性質(zhì)，并由此發(fā)明了避雷針，首先在自己費(fèi)城的住宅安裝了避雷針。此后，避雷針便在世界上流行開(kāi)來(lái)。</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(shuō)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(guó)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(jiàn)表1。我國(guó)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?lè)览灼涓叨葹?～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> 防雷避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="font-size:16px;">避雷針是由美國(guó)科學(xué)家富蘭克林發(fā)明的富蘭克林在研究閃電與人工摩擦產(chǎn)生的電的一致性時(shí)，他就從兩者的類比中作出過(guò)這樣的推測(cè)：既然人工產(chǎn)生的電能被前列吸收，那么閃電也能被前列吸收。他由此設(shè)計(jì)了風(fēng)箏實(shí)驗(yàn)，而風(fēng)箏實(shí)驗(yàn)的成功反過(guò)來(lái)又證實(shí)了他的推測(cè)。他由此設(shè)想，若能在高物上安置一種前列裝置，就有可能把雷電引入地下。富蘭克林把一根數(shù)米長(zhǎng)的細(xì)鐵棒固定在高大建筑物的頂端，在鐵棒與建筑物之間用絕緣體隔開(kāi)。然后用一根導(dǎo)線與鐵棒底端連接。再將導(dǎo)線引入地下。富蘭克林把這種避雷裝置稱為避雷針。經(jīng)過(guò)試用，果然能起避雷的作用。</span>
