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。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百的電荷。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，當云層上度電荷較多時，避雷針與云層之間的空氣就很容易被擊穿，成問為導體。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，鄂州橋梁避雷針廠家排名，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成危險，保證了它的安全。帶電的云，首先是從上往下運行,在高處安避雷針，就首先將云中的電放答掉，鄂州橋梁避雷針廠家排名，鄂州橋梁避雷針廠家排名,以后到房子接觸云的時候，就基本沒有或只有少部分電而沒有危險了</span>

1、所有金屬部件必須鍍鋅，操作時注意保護鍍鋅層。 2、采用鍍鋅鋼管管制作針尖，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、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 5、圓鋼為其直徑的6倍。 6、圓鋼與扁鋼連接時，其長度為圓鋼直徑的6倍。 7、避雷針一般采用圓鋼或鋼管制成，其直徑不應小于下列數(shù)值： **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。</span> </p><h2> 避雷針安裝注意事項 </h2> <p> <span style="font-size:16px;">安裝避雷針必須遵守中華人民國家標準（GB50057—94）《建筑物防雷設計規(guī)范》，具體施工必須嚴格遵循國家標準（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗收規(guī)范，雷雨日不可進行避雷針的安裝和檢測。 ① 定貨時請告知您所選用的避雷針（塔）桿的技術參數(shù)，以便廠方給您選配更規(guī)范的互連過渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當其厚度不小于4mm時，可作避雷針的引下線。筒體底部應有兩處與接地體對稱連接。 ③ 建筑物L的防雷設施采用多根引下線時，宜在各引下線距地面的1.5～1.8m處設置斷接卡，斷接卡應加絕緣保護措施。容 ④ 避雷針與引下線之間的連接應采用焊接。 ⑤ 避雷針其接地裝置，應采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥ 安裝時請勿觸摸主接閃前列、主動放電前列。 ⑦ 產(chǎn)品設計使用壽命20年。</span> 防雷避雷針，湖北乾元上風電氣供應。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鄂州橋梁避雷針廠家排名,避雷針"

(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> 避雷針安裝價格，湖北乾元上風電氣供應，品質(zhì)優(yōu)良！襄陽塔頂避雷針制作公司</p><p
