因為避雷針通過引下線與接地裝置相連接，孝感塔頂避雷針安裝。雷電流擊在避雷針上，其能量通過引下線迅速到達接地裝置，在大地中消除，使被保護物不會受抄到破壞。避雷針，又名防雷針，是用來保護建筑物、高大樹木等避免雷擊的裝置。在被保護物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)線與埋在地下的泄流地網(wǎng)連接起來，孝感塔頂避雷針安裝。避雷針規(guī)格必須符合GB標準，每一個防雷類別需要的避雷針高度規(guī)格都不一樣。當雷云放電接近地面時它使地面電場發(fā)生畸變。在避雷針的頂端，形成局部電場集中的空間，孝感塔頂避雷針安裝，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針放電，再通過接地引下線和接地裝置將雷電流引入大地，從而使被保zd護物體免遭雷擊。</span> 防雷避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！孝感塔頂避雷針安裝</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="孝感塔頂避雷針安裝,避雷針"

style="font-size:16px;">裝置避雷針是避免雷擊的有效方法。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，它自己就負擔了雷的打擊，房屋與人得到了安全。</span> 恩施學(xué)校避雷針廠家哪家好防雷避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，歡迎您來點電咨詢！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="孝感塔頂避雷針安裝,避雷針"

style="font-size:16px;">在雷雨天氣，高樓上空出現(xiàn)帶電云層時，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，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電容器，由于它較尖，即這個電容器的兩極板正對面積很小，電容也就很小，也就是說它所能容納的電荷很少。而它又聚集了大部分電荷，所以，當云層上電荷較多時，避雷針與云層之間的空氣就很容易被擊穿，成為導(dǎo)體。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，使其不對高層建筑構(gòu)成危險，保證了它的安全。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、合理、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> </p><h2> 汽車安裝避雷針嗎 </h2> <p> <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(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>

style="font-size:16px;">雷雨天氣，高樓上空出現(xiàn)帶電云層時，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，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電容器，由于它較尖，即這個電容器的兩極板正對面積很小，電容也就很小，也就是說它所能容納的電荷很少。而它又聚集了大部分電荷，所以，當云層上電荷較多時，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，使其不對高層建筑構(gòu)成危險，保證了它的安全。按我國統(tǒng)計的雷電流幅值約為300 kA，其對應(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區(qū)和散擊區(qū)的地表半徑見表1。我國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，安裝的短針防雷其高度為1～2 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，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！仙桃橋梁避雷針制作公司</p><p style="text-indent:25px">防雷避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！孝感塔頂避雷針安裝</p><h2> 避雷針塔是怎樣避雷的？ </h2> <p> <span style="font-size:16px;">把建筑物中的金屬結(jié)構(gòu)沿鋼筋連成一整體，構(gòu)成一個大型金屬網(wǎng)籠。這種籠式避雷網(wǎng)既起屏蔽作用，又充當引下線，是一種更加經(jīng)濟、美觀的安全的防雷方式。你到大街上轉(zhuǎn)一轉(zhuǎn)，可看到很多新樓的屋頂上不再有高聳的金屬桿和引下線了，那就是因為它們已用上籠式避雷網(wǎng)了。屋頂?shù)母鞣N金屬物都用導(dǎo)體連到籠式避雷網(wǎng)上。在屋頂四周還應(yīng)布設(shè)一條金屬帶，稱避雷帶，把它與避雷網(wǎng)接上。安裝了避雷裝置的建筑物是否就萬無一失不遭雷擊了呢？那不一定。有些高大建筑物雖安裝了避雷裝置，但因接地線斷裂等原因而"有形無用"了。可見要確保避雷裝置發(fā)揮效能，不但要正確設(shè)計、正確安裝，還要經(jīng)常保養(yǎng)，使它經(jīng)常處于良好狀態(tài)，這樣一般就可免受雷害了。眾達小編在這里提醒大家：一定要重視科學(xué)，不要輕視避雷技術(shù)各種環(huán)節(jié)的科學(xué)原理。更不可自以為是地自行安裝避雷針，那是危險的，弄不好，反而會"引雷入室"，反倒遭了雷擊災(zāi)禍，這種事例不少。</span>
