style="font-size:16px;">（一）安裝避雷針時需要注意：（1）建筑物頂部的避雷針必須與頂部的其他金屬物體連成一個整體的電氣通路。（2）不得在避雷針構架上架設低電壓線路或通訊線路。（二）安裝避雷帶和避雷網(wǎng)時需要注意： 1.明裝避雷帶（網(wǎng)）（1）在屋面混凝土支座上的安裝避雷帶（網(wǎng)）的支座既可以在施工過程中現(xiàn)場澆制，也可以預制再砌牢，十堰橋梁避雷針。（2）在女兒墻上的安裝沿女兒墻安裝時，要使用支架固定，盡量隨結構施工預埋支架。若條件受到限制，在墻體施工時需預留不小于100mmx 100mmx 100mm的孔洞，十堰橋梁避雷針，且洞口的大小里外一致。直線段支架的水平間距應為1-1.5m，垂直間距應為1.5-2m，且支架間距應該平均分布，十堰橋梁避雷針。女兒墻上設置的支架應該與墻頂面垂直。 (3)在屋脊或檐口支座、支架上的安裝需要使用混凝土支座或支架固定。現(xiàn)場澆制支座的時候，首先把脊瓦敲去一角，使支座與脊瓦內的砂漿連成一體；固定支架時，用電鉆將脊瓦鉆孔，再將支架插入孔內，用水泥砂漿填塞牢固。支座和支架的水平間距為1-1.5m，轉彎處為0.25m-0.5m。</span> 避雷針價格，湖北乾元上風電氣供應，歡迎您來點電咨詢！十堰橋梁避雷針</p><div

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> 仙桃信號避雷針檢測避雷針廠家，湖北乾元上風電氣供應，品質優(yōu)良值得推薦！</p><div style="width:100%;text-align: center;"><img

style="font-size:16px;">安裝避雷針時，應注意以下事項： 1、在選擇**避雷針的裝設地點時，應使避雷針及其接地裝置與配電裝置之間抄保持以下規(guī)定的距離：在地面上，由**避雷針到配電裝置的導電部分以及到變電所電氣設備和構架地部分間的空間距離不應小于6m,在地下，由**避襲雷針本身的接地裝置與變電所接地網(wǎng)間近的地中距離一般不小于3m。 2、**避雷針的接地電阻一般不宜超過10Ω。 3、為了防止雷擊避雷針時，雷電波由電線傳入室內，危及人身安全，所以不得在避雷針構架上架設電壓線路或通信線路。裝有避雷針的構架上的照明燈電源線，必須采用直埋于地下的帶金屬保護層的電纜或穿入金屬管的導線。電纜保護層或金屬管必百須接地，埋地長度在10m以上，方可與配電裝置的接地網(wǎng)連接，貨與電源線度、低壓配電裝置相連接。</span> </p><h2> 避雷針為能避雷的原因 </h2> <p> 在雷雨天氣，高樓上空出現(xiàn)帶電云層時，迅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，而靜電感應時，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。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人大地，使其不對高層建筑構成危險，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。以更好的工程質量和服務態(tài)度回報社會及廣大客戶的信任與厚愛。防雷避雷針安裝廠家，湖北乾元上風電氣供應，品質有保障！</p><div

避雷針可以避雷的原理： </h2> <p> <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。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入大地，使其不對高層建筑構成危險，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>

1、直擊雷適用于石化倉庫、廣播電視、加油站、建筑大樓、信標臺，通信基站、氣象臺、基地、雷達機房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達基站、信標臺，通信基站、基地、雷達機房、銀行大樓、天文氣象臺等重要場所。 3、預放電當避雷針截受雷擊時，由接閃體接閃，通過雷電波形處理裝置，利用外殼與中心接地桿之間有3mm間隙，構成耦合電容，同時外殼通過一個電感線圈接地（中心接地桿）當下行先導接近接閃器時，由于頻率極高，電感呈開路狀態(tài)，電容對高頻呈現(xiàn)短路特性。因此耦合電容作用下，接閃器表面電場強度迅速增加，直至觸發(fā)雪崩過程，從而能在頃刻間將雷電流泄放入地，以至有效的達到防雷害保安全的目的。</span>
