(1)接地體頂面埋設深度應符合設計要求。當無要求時，不應小于0.6m。角鋼及鋼管接地體應垂直配置。除接地體外，接地體引出線的垂直部分和接地裝置焊接部位應防腐處理;在作防腐處理前，表面必須除銹并去掉焊接處殘留的焊藥。 (2)垂直接地體的間距不應小于其長度的3~5倍。水平接地體的間距應符合設計規(guī)定。當無設計規(guī)定時不宜小于5m。 (3)除環(huán)形接地體外，接地體埋設位置應在距建筑物3m以外。距建筑物出入口或人行道也應大于3m，如小于3m時，應采用均壓帶做法或在接地裝置上面敷設50~90mm厚度的瀝青層，其寬度應超過接地裝置2m。 (4)利用底板鋼筋或深基礎做接地體：按設計圖尺寸位置要求，標好位置，將底板鋼盤搭接焊好，再將柱主筋(不少于2根)底部與底板筋搭接焊，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標記，以便引出和檢查。 (5)利用柱形樁基及平臺鋼筋做接地體：按設計圖尺寸位置，找好樁基組數(shù)位置，把每組樁基四角鋼盤搭接封焊，再與柱主筋(不少于2根)焊好，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標記，以便引出和檢查。</span> 襄陽橋梁避雷針防雷避雷針廠家，湖北乾元上風電氣供應，品質有保障！</p><div style="width:100%;text-align:

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，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|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> </p><h2> 避雷針的保護范圍是多少？ </h2> <p> <span style="display:none;"></span><span style="font-size:16px;">避雷針的工作原理就其本質而言，避雷針不是避雷，而是利用其高聳空中的有利地來位，把雷電引向自身，承受雷擊。同時把雷電流泄入大地，起著保護其附源近比它矮的建筑物或設備免受雷擊的作用。簡單一點說，一級保護是以30米為半徑、二級保護是45米為半百徑、三級保護是60米為半徑做弧的保護范圍。計算方法避雷針的保護半徑與高度（h）有關，以及與所現(xiàn)的滾球半徑有關， D為滾球半徑（度閃擊距離）類建筑物為D＝30米第二類建筑物為D＝45米第三類建筑物為D＝60米保護范圍采用規(guī)范之計算公式： Rx=?{h(2hr-h)}-?{hx(2hr-hx)} 其中Rx為避雷針在距離地問面hx米處的保護半徑（米）； hr為滾球半徑,根據(jù)建筑物類別取值30、45、60； hx為被保護物的高度一般來說，避雷針越高，保護范圍就越大，保護效果也越好，但考慮到避雷針建設的安全性和經(jīng)濟答性，避雷針大多建設在35米-45米之間。</span> 避雷針廠家，湖北乾元上風電氣供應，品質有保證！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

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，遭到雷擊的災禍</span>

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>
