src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372812500/1888634.jpg"></div><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> 荊州避雷針檢測防雷避雷針安裝公司，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="襄陽塔頂避雷針安裝廠家,避雷針" src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452424707031/2495206.jpg"></div><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。 </p><h2> 建筑物在多少高度必須安裝避雷針 </h2> <p> <span style="font-size:16px;">并不是規(guī)定有多少層需要裝避雷針，要看樓房是不是在避雷帶保護半徑之內。就是說房子如果50層，旁邊如果也有一個51層的樓房上裝了避雷針，如果樓房在避雷針保護半徑之內，也可以不用裝。如果房子只有三層，但是在當?shù)氐狞c，附近也有沒有裝避雷針，這樣也需要裝避雷針。避雷針的種類：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>

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> 防雷避雷針，湖北乾元上風電氣供應，品質優(yōu)良值得推薦！黃石橋梁避雷針</p><p
