style="font-size:16px;">避雷針是保護建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個金屬棒，用金屬線與埋在地下的一塊金屬板連接起來，利用金屬棒的前列放電，使云層所帶的電和地上的電逐漸中和。唐代《炙轂子》一書在記載了這樣一件事：漢朝時柏梁殿遭到火災(zāi)，一位巫師建議，將一塊魚尾形狀的銅瓦放在層頂上，就可以主防止雷電所引起的天火。屋頂上所設(shè)置的魚尾開頭的瓦飾，實際上兼作避雷之用，可認為是現(xiàn)代避雷針的雛形。而早在以前，中國已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國新事》一書中記有：中國屋脊兩頭，都有一個仰起的**，龍口吐出曲折的金屬舌頭，伸向天空，舌根連結(jié)一根細的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時刻就大顯神通，若雷電擊中了屋宇，天門變電站避雷針加工廠家，電流就會從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說明，天門變電站避雷針加工廠家，中國古代建筑上的如雷裝置，在大批量和結(jié)構(gòu)上已和現(xiàn)代避雷針基本相似，天門變電站避雷針加工廠家。</span>

style="font-size:16px;">避雷針通過導(dǎo)線接入地下，與地面形成等電位差，利用自身的高度，使電場強度增加到極限值的雷電云電場發(fā)生畸變，開始電離并下行先導(dǎo)放電；避雷針在強電場作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電；兩者會合形成雷電通路，隨之瀉入大地，達到避雷效果。常用避雷針保護范圍的計算方法主要有折線法和滾球法?！罢劬€法”的主要特點是設(shè)計直觀，計算簡便，可節(jié)省投資，但不適用于高度大于20m的建筑物；“滾球法”的主要特點是可以計算避雷針或避雷帶與網(wǎng)格組合時的保護范圍。（詳細知識可以咨詢湖北乾元上風(fēng)電氣工程有限公司）湖北乾元上風(fēng)電氣工程有限公司堅持“安全為先、服務(wù)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(shè)計和施工。我們以質(zhì)量的技術(shù)力量和良好的服務(wù)態(tài)度為您的防雷工程提供多方面的解決方案和技術(shù)支持，做到科學(xué)設(shè)計、科學(xué)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(shè)備和人身的安全防護工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報社會及廣大客戶的信任與厚愛</span>。荊門避雷針安裝廠家避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)，歡迎您來點電咨詢！</p><div

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452432724610/5832678.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(yù)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(yù)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(gòu)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(dǎo)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> </p><h2> 安裝避雷針需要注意的事項 </h2> <p> <span 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(gòu)架上架設(shè)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(yù)制再砌牢。（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(jié)構(gòu)施工預(yù)埋支架。若條件受到限制，在墻體施工時需預(yù)留不小于100mmx 100mmx 100mm的孔洞，且洞口的大小里外一致。直線段支架的水平間距應(yīng)為1-1.5m，垂直間距應(yīng)為1.5-2m，且支架間距應(yīng)該平均分布。女兒墻上設(shè)置的支架應(yīng)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?，F(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(nèi)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(nèi)，用水泥砂漿填塞牢固。支座和支架的水平間距為1-1.5m，轉(zhuǎn)彎處為0.25m-0.5m。</span>
