style="font-size:16px;">避雷針是由美國科學(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這樣的推測：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)的成功反過來又證實(shí)了他的推測。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。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)過試用，果然能起避雷的作用。</span>

style="font-size:16px;">并不是規(guī)定有多少層需要裝避雷針，要看樓房是不是在避雷帶保護(hù)半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個(gè)51層的樓房上裝了避雷針，如果樓房在避雷針保護(hù)半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當(dāng)?shù)氐狞c(diǎn)，附近也有沒有裝避雷針，這樣也需要裝避雷針。避雷針的種類：直擊雷避雷針/特殊避雷針/提前預(yù)放電避雷針 1、直擊雷適用于石化倉庫、廣播電視、加油站、建筑大樓、信標(biāo)臺，通信基站、氣象臺、基地、雷達(dá)機(jī)房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達(dá)基站、信標(biāo)臺，通信基站、基地、雷達(dá)機(jī)房、銀行大樓、天文氣象臺等重要場所。 3、預(yù)放電當(dāng)避雷針截受雷擊時(shí)，由接閃體接閃，通過雷電波形處理裝置，利用外殼與中心接地桿之間有3mm間隙，構(gòu)成耦合電容，同時(shí)外殼通過一個(gè)電感線圈接地（中心接地桿）當(dāng)下行先導(dǎo)接近接閃器時(shí)，由于頻率極高，電感呈開路狀態(tài)，電容對高頻呈現(xiàn)短路特性。因此耦合電容作用下，接閃器表面電場強(qiáng)度迅速增加，直至觸發(fā)雪崩過程，從而能在頃刻間將雷電流泄放入地，以至有效的達(dá)到防雷害保安全的目的。</span>
