style="font-size:16px;">據(jù)中國的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個(gè)錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。 “折線法”是比較成熟的方法，在電力系統(tǒng)又稱“規(guī)程法”，即單支避雷針的保護(hù)范圍是一個(gè)以避雷針為軸的折線圓錐體。單支避雷針的保護(hù)范圍在DL/T620-997《交流電氣裝置的過電壓保護(hù)和絕緣配合》標(biāo)準(zhǔn)中有所規(guī)定；“滾球法”是國際電工會(huì)（IEC）推薦的接閃器保護(hù)范圍計(jì)算方法之一。我國建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強(qiáng)制作為計(jì)算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個(gè)球體沿需要防止擊雷的部位滾動(dòng)，當(dāng)球體只觸及接閃器（包括被用作接閃器的金屬物）或只觸及接閃器和地面（包括與大地接觸并能承受雷擊的金屬物），而不觸及需要保護(hù)的部位時(shí)，則該部分就得到接閃器的保護(hù)。</span>

style="font-size:16px;">再也不怕打雷了防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是通常所說的''避雷針''，它通過引下線和接地裝置與大地相連。由于''前列放電''效應(yīng)，大地被感應(yīng)出的電荷易聚集在針尖處，使得雷云與避雷針附近空間的電場強(qiáng)度相對(duì)較大，空氣也容易被擊穿，雷電流通過避雷針提供的放電通道泄放入地。這樣，雷擊雖然還是發(fā)生了，但總是擊向避雷針，而不是擊向要保護(hù)的物體，所以避雷針實(shí)際是引雷針。它將雷電吸引至自身，使雷電流通過引下線至接地裝置而泄放大地，從而使保護(hù)對(duì)象免遭雷擊。避雷針的保護(hù)范圍可用滾球法來確定。在一定范圍內(nèi)，隨著避雷針的增高，其保護(hù)范圍也隨之?dāng)U大，達(dá)到一定高度以后，其保護(hù)范圍就不再擴(kuò)大了。避雷針的高度是這樣確定的：對(duì)于類、第二類和第三類防雷建筑物，避雷針的有效高度分別為30米、45米和60米，所以盲目增加避雷針高度，既浪費(fèi)又無實(shí)際效果。</span> </p><h2> 避雷針安裝的注意事項(xiàng) </h2> <p> <span style="font-size:16px;"> (1)接地體頂面埋設(shè)深度應(yīng)符合設(shè)計(jì)要求。當(dāng)無要求時(shí)，不應(yīng)小于0.6m。角鋼及鋼管接地體應(yīng)垂直配置。除接地體外，接地體引出線的垂直部分和接地裝置焊接部位應(yīng)防腐處理;在作防腐處理前，表面必須除銹并去掉焊接處殘留的焊藥。 (2)垂直接地體的間距不應(yīng)小于其長度的3~5倍。水平接地體的間距應(yīng)符合設(shè)計(jì)規(guī)定。當(dāng)無設(shè)計(jì)規(guī)定時(shí)不宜小于5m。 (3)除環(huán)形接地體外，接地體埋設(shè)位置應(yīng)在距建筑物3m以外。距建筑物出入口或人行道也應(yīng)大于3m，如小于3m時(shí)，應(yīng)采用均壓帶做法或在接地裝置上面敷設(shè)50~90mm厚度的瀝青層，其寬度應(yīng)超過接地裝置2m。 (4)利用底板鋼筋或深基礎(chǔ)做接地體：按設(shè)計(jì)圖尺寸位置要求，標(biāo)好位置，將底板鋼盤搭接焊好，再將柱主筋(不少于2根)底部與底板筋搭接焊，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標(biāo)記，以便引出和檢查。 (5)利用柱形樁基及平臺(tái)鋼筋做接地體：按設(shè)計(jì)圖尺寸位置，找好樁基組數(shù)位置，把每組樁基四角鋼盤搭接封焊，再與柱主筋(不少于2根)焊好，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標(biāo)記，以便引出和檢查。</span> 防雷避雷針，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！</p><div

1、在選擇**避雷針的裝設(shè)地點(diǎn)時(shí)，應(yīng)使避雷針及其接地裝置與配電裝置之間抄保持以下規(guī)定的距離：在地面上，由**避雷針到配電裝置的導(dǎo)電部分以及到變電所電氣設(shè)備和構(gòu)架地部分間的空間距離不應(yīng)小于6m,在地下，由**避襲雷針本身的接地裝置與變電所接地網(wǎng)間近的地中距離一般不小于3m。 2、**避雷針的接地電阻一般不宜超過10Ω。 3、為了防止雷擊避雷針時(shí)，雷電波由電線傳入室內(nèi)，危及人身安全，所以不得在避雷針構(gòu)架上架設(shè)電壓線路或通信線路。裝有避雷針的構(gòu)架上的照明燈電源線，必須采用直埋于地下的帶金屬保護(hù)層的電纜或穿入金屬管的導(dǎo)線。電纜保護(hù)層或金屬管必百須接地，埋地長度在10m以上，方可與配電裝置的接地網(wǎng)連接，貨與電源線度、低壓配電裝置相連接。</span> 防雷避雷針安裝廠家，湖北乾元上風(fēng)電氣供應(yīng)。武漢塔頂避雷針制作</p><p style="text-indent:25px">防雷避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！潛江避雷針廠家排名</p><h2> 農(nóng)村民用樓房怎么安裝避雷針? </h2> <p> <span style="font-size:16px;">分時(shí)段安裝： 1、做基礎(chǔ)時(shí)，安裝接地極： 2、結(jié)構(gòu)施工時(shí)利用結(jié)構(gòu)內(nèi)鋼筋（或**型鋼）做引下線，與接地極連接，并預(yù)留與避雷帶的連接點(diǎn)； 3、裝修完成的同時(shí)，敷設(shè)避雷帶（或避雷針）。避雷針的原理：在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，避雷針和高樓頂部都被感應(yīng)上大量電荷，由于避雷針針頭是尖的，所以靜電感應(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，避雷針就可以把云層上的電荷導(dǎo)入大地，使其不對(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</span>
