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，黃石橋梁避雷針廠家排名。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，黃石橋梁避雷針廠家排名，多方面、安全，黃石橋梁避雷針廠家排名、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。避雷針安裝，湖北乾元上風電氣供應，歡迎您來點電咨詢！黃石橋梁避雷針廠家排名</p><div

style="font-size:16px;">優(yōu)化避雷針在電場的作用下，其球型電觸發(fā)裝置在瞬間產(chǎn)生強大的感應電壓，在針尖迅速聚集大量的與下行優(yōu)化相反的異種電荷，當聚集的異種電荷達到一定強度，便迅速向上運動，從而產(chǎn)生一個上行優(yōu)化。上行優(yōu)化向上傳播一直到與下行優(yōu)化匯合，此時，閃電電流便流過新形成的通道。優(yōu)化避雷針根據(jù)電磁學原理進行了特殊的優(yōu)化設計，使其對雷電能提前優(yōu)化，首先使避雷針的滾球半徑增大，在同等條件下可降低避雷針的高度。其次，由于其對雷電提前優(yōu)化效果較好，其在雷云聚集能量不足夠多、云地之間的電場不是足夠大時提前觸發(fā)，閃擊的雷電流相對于普通避雷針要少得多，接閃避雷針周圍的感應電磁、場也要少得多，二次雷擊的危險也將降低，從而達到很好的保護效果。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。</span>

style="font-size:16px;">一、避雷針的安裝避雷針（接閃器）的安裝主要包括避雷針的安裝和避雷帶（網(wǎng)）的安裝。（一）避雷針的安裝安裝注意事項如下：（1）建筑物上的避雷針和建筑物頂部的其他金屬物體應連接成一個整體。（2）不得在避雷針構架上架設低壓線路或通訊線路。（二）避雷帶和避雷網(wǎng)的安裝 1.明裝避雷帶（網(wǎng)）安裝適于安裝在建筑物的屋脊、屋檐（坡屋頂）或屋頂邊緣及女兒墻（平屋頂）等處。（1）避雷帶在屋面混凝土支座上的安裝避雷帶（網(wǎng)）的支座可以在建筑物屋面面層施工過程中現(xiàn)場澆制，也可以預制再砌牢或與屋面防水層進行固定。 ( 2)避雷帶在墻或天溝支架上的安裝沿墻安裝時，應使用支架固定；并應盡量隨結構施工預埋支架。支架的支起高度不應小于150mm 。直線段支架水平間距為1-1. 5m，垂直間距為1. 5-2m，且支架間距應平均分布。避雷帶（網(wǎng)）在建筑物天溝上安裝使用支架固定時，應隨土建施工先設置好預埋件，支架與預埋件進行焊接固定。</span> </p><h2> 什么是雷電現(xiàn)象？ </h2> <p> <span style="font-size:16px;">所謂雷電現(xiàn)象，就是空中云層積累的電荷達到頗大數(shù)量時，它與附近的帶電云層或物體間產(chǎn)生很大的電勢差，形成很強的電場，兩部分異性電荷突破周圍空氣的阻礙去中和，發(fā)生強烈放電，這時在電通過的路徑上發(fā)出聲和光，就是雷電。雷電通常發(fā)生在不同的云塊之間，或云的下部與地面物之間。我們要避免的只是云和地或地上物之間的雷電。如果這塊云的上部帶正電，下部帶負電，則地面上感應出來的電是正電，此時地面上的凸出物（房屋、樹或人體）就有可能與云中電荷發(fā)生放電現(xiàn)象，遭到雷擊的災禍</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452424677735/7004600.jpg"></div><h2> 避雷針的種類： </h2> <p> <span style="font-size:16px;">直擊雷避雷針/特殊避雷針/提前預放電避雷針 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>
