style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應(yīng)雷電和綜合性防雷電。防直擊雷電的避雷裝置一般由三部分組成，即接閃器、引下線和接地體；接閃器又分為避雷針、避雷線、避雷帶、避雷網(wǎng)。以避雷針作為接閃器的防雷電原理是：避雷針通過導(dǎo)線接入地下，與地面形成等電位差，利用自身的高度，使電場強度增加到極限值的雷電云電場發(fā)生畸變，開始電離并下行先導(dǎo)放電；避雷針在強電場作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電；兩者會合形成雷電通路，隨之瀉入大地，達到避雷效果。實際上，避雷針是引雷針，可將周圍的雷電引來并提前放電，將雷電電流通過自身的接地導(dǎo)體傳向地面，潛江學(xué)校避雷針安裝廠家，避免保護對象直接遭雷擊。湖北乾元上風(fēng)電氣工程有限公司堅持“安全為先、服務(wù)為先、信譽為先”的經(jīng)營宗旨，并以“質(zhì)量至上、注重實效”的原則貫穿于各項工程的設(shè)計和施工。我們以質(zhì)量的技術(shù)力量和良好的服務(wù)態(tài)度為您的防雷工程提供多方面的解決方案和技術(shù)支持，做到科學(xué)設(shè)計、科學(xué)施工，多方面、安全，潛江學(xué)校避雷針安裝廠家、合理，潛江學(xué)校避雷針安裝廠家、經(jīng)濟的做好各類防雷建筑物的雷電防御及設(shè)備和人身的安全防護工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報社會及廣大客戶的信任與厚愛。</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(dāng)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(dǎo)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?dǎo)電性物質(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>

——★1避雷針是利用前列放電的原理，吸收雷電達到保護復(fù)作用。避雷針是保護某一片區(qū)域的，所以設(shè)置高度很高（具體高度，需要根據(jù)保護面積作復(fù)雜的計算），并且要有很高的強度要求，可以很好的吸收【直擊雷】的放電。 ——★2、建筑物避雷帶的避雷原理同避雷針相同，但是： ①、保護目的為建筑物自己，因此不制需要特別的高度等質(zhì)量要求； ②、一般的建筑物遭受直擊雷的可能性極低（高層建筑除外），主要防止【感應(yīng)雷】對建筑物的損害，一百般避雷帶足以滿足要求。 ——★3、直擊雷與感應(yīng)雷的區(qū)別： ①、直擊雷就是雷電直接與地面物體放電，釋放能量； ②、距離帶電云彩較近的建筑物，會度積聚與帶電云彩相反極性的、相同數(shù)量的電荷，當(dāng)帶電云彩突然失去電荷（如云彩之間放電），積聚在建筑物上的電荷就失去吸引力而四處泄放，這就是感應(yīng)雷。對于避雷針的材料，有很多種</span> </p><h2> 避雷器與避雷針區(qū)別： </h2> <p> <span 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。避雷針和被保護物體是分開的，可以保護比較集中的重要物體。 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入大地。避雷器和被保護物體是連接的，可以保護帶電物體，如輸電線路。避雷器工作原理：避雷器實百際上是一種非線性極好的電阻，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。避雷器在電力系統(tǒng)中與被保護設(shè)備并聯(lián)，正常時泄漏電流很小，不影響系統(tǒng)運行。當(dāng)系統(tǒng)有過電壓時（即超過正常運行電壓的高電壓），避雷器即呈現(xiàn)低電阻泄放答能量，同時限制系統(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;">在房屋處豎一金屬棒，棒下端連一條足夠粗的銅線，銅線下端連一塊金屬板埋入地下深處潮濕處。金屬棒的上端須是一個尖頭或分叉為幾個尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時。避雷針的前列因靜電感應(yīng)就集中了異種電荷，發(fā)生前列放電，與云內(nèi)的電相中和，避免發(fā)生激烈的雷電、這就是避雷針能避雷的一方面。但這種作用頗慢，如果云中積電很快，或一塊帶有大量電荷的云突然飛來，有時來不及按上述方式中和，于是有強烈的放電，加雷電仍會發(fā)生。但這時由于避雷針高過周圍物體，它的前列又集中了與云中電異號的電荷，如果雷電是在云和地面物之間發(fā)生，放電電流主要通過避雷針流入大地，因此，不會打在房屋或附近人的身上，只會打在避雷針上了。由此可見，避雷針的前列放電作用會減少地面物與云之間打雷的可能性；到了不可避免時，它自己就負擔(dān)了雷的打擊，房屋與人得到了安全。由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，斷口以上的一段就成為一個隔離的導(dǎo)電系統(tǒng)。</span>
