style="font-size:16px;">避雷，實際上是引雷德作用原理：在雷雨天氣，高樓上空出現(xiàn)帶電云層時，迅雷針和高樓頂知部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，而靜電感應(yīng)時，導(dǎo)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道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，黃石工廠避雷針制作，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，避雷針與云層之版間的空氣就很容易被擊穿，黃石工廠避雷針制作，成為導(dǎo)體．這樣，帶電云層與避雷針形成通路，而避雷針又是接地的．避雷針就可以權(quán)把云層上的電荷導(dǎo)人大地，黃石工廠避雷針制作，使其不對高層建筑構(gòu)成危險，保證了它的安全。</span>

style="font-size:16px;">避雷針的工作原理就其本質(zhì)而言，避雷針不是避雷，而是利用其高聳空中的有利地來位，把雷電引向自身，承受雷擊。同時把雷電流泄入大地，起著保護其附源近比它矮的建筑物或設(shè)備免受雷擊的作用。簡單一點說，一級保護是以30米為半徑、二級保護是45米為半百徑、三級保護是60米為半徑做弧的保護范圍。計算方法避雷針的保護半徑與高度（h）有關(guān)，以及與所現(xiàn)的滾球半徑有關(guān)， D為滾球半徑（度閃擊距離）類建筑物為D＝30米第二類建筑物為D＝45米第三類建筑物為D＝60米保護范圍采用規(guī)范之計算公式： Rx=?{h(2hr-h)}-?{hx(2hr-hx)} 其中Rx為避雷針在距離地問面hx米處的保護半徑（米）； hr為滾球半徑,根據(jù)建筑物類別取值30、45、60； hx為被保護物的高度一般來說，避雷針越高，保護范圍就越大，保護效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟答性，避雷針大多建設(shè)在35米-45米之間。</span> 隨州別墅避雷針制作公司避雷針安裝價格，湖北乾元上風電氣供應(yīng)。</p><div style="width:100%;text-align: center;"><img

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> </p><h2> 汽車安裝避雷針嗎 </h2> <p> <span style="font-size:16px;">汽車不安裝避雷針，但車殼是金屬的，因屏蔽作用，就算閃電擊中汽車，也不會傷人，因此，車廂是躲避雷擊的理想地方。汽車的輪胎絕緣性能相當好，雷電擊到汽車帶電，但電流傳不到地下形不成回路，不會對人和汽車造成危害。汽車的輪胎外帶有水或其它導(dǎo)電性物質(zhì)，有的帶有防靜電接地線。雷電擊到汽車帶電，電流有從金屬表面流動的特性，不會對人產(chǎn)生危害。電流就通過汽車表面?zhèn)鞯綆в兴蚱渌鼘?dǎo)電性物質(zhì)的輪胎，帶有防靜電接地線傳到地下形成回路，不會對人和汽車造成危害。</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(nèi)。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(nèi)，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(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>
