style="font-size:16px;">1，孝感建筑物避雷針加工廠家、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，孝感建筑物避雷針加工廠家。利用過電壓放電現(xiàn)象讓雷擊電壓通過避雷器進入大地，孝感建筑物避雷針加工廠家。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)中與被保護設備并聯(lián)，正常時泄漏電流很小，不影響系統(tǒng)運行。當系統(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，確保電氣設備的絕緣不被擊穿。</span>

style="font-size:16px;">1、將支座鋼板固定在預埋的地腳螺栓上,焊上一塊肋板,再將避雷針立起,找直、找正后,進行點焊,然后加以校正,焊上其他三塊脅板。將引下線焊接在底板上,清理藥皮刷防銹漆。 2、避雷針應垂直安裝牢固。垂直度允許偏差為3/1000。 3、針體彎曲，安裝的垂直度超出允許偏差。應將針體重新調(diào)直，符合要求后再安裝。 4、**避雷針及其接地裝置與道路或建筑物的出入口保護距離不符合規(guī)定。其距離應大于3m，當小于3m時，應采取均壓措施或鋪設卵石或瀝青地。 5、選購時應注意：**避雷針一般采用直徑為19mm鍍鋅圓鋼；屋面上的避雷針采用直徑25mm鍍鋅鋼管；水塔頂部避雷針采用直徑25mm或40mm的鍍鋅鋼管；囪頂上避雷針采用直徑25mm鍍鋅圓鋼或直徑為40mm鍍鋅鋼管e避雷環(huán)用直徑12mm鍍鋅圓鋼或截面為100mm2鍍鋅扁鋼，其厚度應為4mm等。 6、注意：避雷針如果沒接地將是個迎雷針，所以必須謹慎。</span>

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上大量電荷，由于避雷針針頭是尖的，所以靜電感應時，導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。湖北乾元上風電氣工程有限公司堅持“安全為先、服務為先、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計和施工。我們以質(zhì)量的技術力量和良好的服務態(tài)度為您的防雷工程提供多方面的解決方案和技術支持，做到科學設計、科學施工，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備和人身的安全防護工作。以更好的工程質(zhì)量和服務態(tài)度回報社會及廣大客戶的信任與厚愛。</span> </p><h2> 避雷針安裝要挖地多深 </h2> <p> <span style="font-size:16px;">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。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。 1、裝置避雷針是避免雷擊的有效方法。在房屋高處豎一金屬棒，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。 2、避雷針的前列因靜電感應就集中了異種電荷，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。</span> 防雷避雷針安裝，湖北乾元上風電氣供應。</p><div

2、采用鍍鋅鋼管管制作針尖知，管壁厚度不得小于3mm,針尖刷錫長度不得小于70mm 3、避雷針應垂直安裝牢固。垂直度允許偏差為3/1000。 4、焊接要求焊接應采用搭接焊，其搭接長度必須符合下列規(guī)定： 5、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 6、圓鋼為其直徑的6倍。 7、圓鋼與扁鋼連接時，其長度為圓鋼直徑的6倍。湖北乾元上風電氣工程有限公司堅持“安全為先、服務為先、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計和施工。</span> 避雷針廠家，湖北乾元上風電氣供應，品質(zhì)有保證！十堰信號避雷針安裝</p><p

——★1避雷針是利用前列放電的原理，吸收雷電達到保護復作用。避雷針是保護某一片區(qū)域的，所以設置高度很高（具體高度，需要根據(jù)保護面積作復雜的計算），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，這就是感應雷。對于避雷針的材料，有很多種</span> 孝感建筑物避雷針加工廠家</p><p
