style="font-size:16px;">避雷針是由美國科學家富蘭克林發(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，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。他由此設計了風箏實驗，而風箏實驗的成功反過來又證實了他的推測。他由此設想，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。然后用一根導線與鐵棒底端連接。再將導線引入地下。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>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372587891/689265.jpg"></div><h2> 建筑物在多少高度必須安裝避雷針 </h2> <p> <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半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個51層的樓房上裝了避雷針，如果樓房在避雷針保護半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當?shù)氐狞c，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、信標臺，通信基站、氣象臺、基地、雷達機房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達基站、信標臺，通信基站、基地、雷達機房、銀行大樓、天文氣象臺等重要場所。 3、預放電當避雷針截受雷擊時，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，同時外殼通過一個電感線圈接地（中心接地桿）當下行先導接近接閃器時，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，以至有效的達到防雷害保安全的目的。</span> </p><h2> 避雷針的作用是什么 </h2> <p> <span style="font-size:16px;">避雷針，又名防雷針、接閃桿，是用來保護建筑物、高大樹木等避免雷擊的裝置。避雷針由接閃器、接地引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。當雷云對地放電通道發(fā)展到臨近地面時，由于避雷針前列突出地面并有良好接地，在針尖附近的電場強度提高，聚積相反極性的電荷，引導放電。進而防止建筑物或儀器蓄積過多電荷而遭受雷擊。一般來講，雷電并不會直接擊中避雷針，而避雷針本身如果被閃電擊中也有著融化及的危險。避雷針具有一定的保護作用.</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513373056641/8168154.jpg"></div><h2> 避雷針的作用 </h2> <p> <span style="font-size:16px;">再也不怕打雷了防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是通常所說的''避雷針''，它通過引下線和接地裝置與大地相連。由于''前列放電''效應，大地被感應出的電荷易聚集在針尖處，使得雷云與避雷針附近空間的電場強度相對較大，空氣也容易被擊穿，雷電流通過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，而不是擊向要保護的物體，所以避雷針實際是引雷針。它將雷電吸引至自身，使雷電流通過引下線至接地裝置而泄放大地，從而使保護對象免遭雷擊。避雷針的保護范圍可用滾球法來確定。在一定范圍內(nèi)，隨著避雷針的增高，其保護范圍也隨之擴大，達到一定高度以后，其保護范圍就不再擴大了。避雷針的高度是這樣確定的：對于類、第二類和第三類防雷建筑物，避雷針的有效高度分別為30米、45米和60米，所以盲目增加避雷針高度，既浪費又無實際效果。</span>

style="font-size:16px;">汽車不安裝避雷針，但車殼是金屬的，因屏蔽作用，就算閃電擊中汽車，也不會傷人，因此，車廂是躲避雷擊的理想地方。汽車的輪胎絕緣性能相當好，雷電擊到汽車帶電，但電流傳不到地下形不成回路，不會對人和汽車造成危害。汽車的輪胎外帶有水或其它導電性物質(zhì)，有的帶有防靜電接地線。雷電擊到汽車帶電，電流有從金屬表面流動的特性，不會對人產(chǎn)生危害。電流就通過汽車表面?zhèn)鞯綆в兴蚱渌鼘щ娦晕镔|(zhì)的輪胎，帶有防靜電接地線傳到地下形成回路，不會對人和汽車造成危害。</span>
