style="font-size:16px;">避雷針，又名防雷針、接閃桿，是用來(lái)保護(hù)建筑物、高大樹(shù)木等避免雷擊的裝置。避雷針由接閃器、接地引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長(zhǎng)度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。當(dāng)雷云對(duì)地放電通道發(fā)展到臨近地面時(shí)，由于避雷針前列突出地面并有良好接地，在針尖附近的電場(chǎng)強(qiáng)度提高，聚積相反極性的電荷，引導(dǎo)放電。進(jìn)而防止建筑物或儀器蓄積過(guò)多電荷而遭受雷擊。一般來(lái)講，雷電并不會(huì)直接擊中避雷針，而避雷針本身如果被閃電擊中也有著融化及的危險(xiǎn)。避雷針具有一定的保護(hù)作用.</span>

style="font-size:16px;">1、避雷針，又名防雷針、接閃桿，是用來(lái)保護(hù)建筑物、高大樹(shù)木等避免雷擊的裝置。在被保護(hù)物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)線與埋在地下的泄流地網(wǎng)連接起來(lái)。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個(gè)防雷類別需要的避雷針高度規(guī)格都不一樣。 2、當(dāng)雷云放電接近地面時(shí)它使地面電場(chǎng)發(fā)生畸變。在避雷針的頂端，形成局部電場(chǎng)集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針?lè)烹?，再通過(guò)接地引下線和接地裝置將雷電流引入大地，從而使被保護(hù)物體免遭雷擊。 3、由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，斷口以上的一段就成為一個(gè)隔離的導(dǎo)電系統(tǒng)。 4、當(dāng)云中有電荷時(shí)，這隔出的部分上部感應(yīng)出與云中電異號(hào)的電荷，而下部感應(yīng)出與云中電同號(hào)的電荷，如果上部和云中電起放電作用時(shí)，強(qiáng)大的放電電流只能通過(guò)建筑物放出大量熱量，于是引起雷擊。這樣不但不能避雷，反而還招來(lái)雷禍。為防意外，高大建筑物豎起幾條避雷針。另外，每一又避雷針只能保護(hù)一定的建筑面積。對(duì)于較大的建筑物也需要豎起幾條避雷針。</span> </p><h2> 安裝避雷針需要注意的事項(xiàng) </h2> <p> <span style="font-size:16px;">（一）安裝避雷針時(shí)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(gè)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(shí)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(guò)程中現(xiàn)場(chǎng)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(shí)，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(shí)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(chǎng)澆制支座的時(shí)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(shí)，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>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372724610/4217025.jpg"></div><h2> 避雷針有什么用途 </h2> <p> <span style="font-size:16px;">避雷，實(shí)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(shí)，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(shí)，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(gè)電容器，由于它較尖，即這個(gè)電容器的兩極板正對(duì)面積很小，電容也就很小，也就是說(shuō)它所能容納的電荷很少．而它又聚集了大部分電荷，所以，當(dāng)云層上電荷較多時(shí)，避雷針與云層之版間的空氣就很容易被擊穿，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，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</span>
