style="font-size:16px;">裝置避雷針是避免雷擊的有效方法。在房屋處豎一金屬棒，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(gè)尖頭或分叉為幾個(gè)尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時(shí)。避雷針的前列因靜電感應(yīng)就集中了異種電荷，發(fā)生前列放電，與云內(nèi)的電相中和，避免發(fā)生激烈的雷電，黃石學(xué)校避雷針安裝、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(shí)來不及按上述方式中和，于是有強(qiáng)烈的放電，加雷電仍會發(fā)生。但這時(shí)由于避雷針高過周圍物體，它的前列又集中了與云中電異號的電荷，如果雷電是在云和地面物之間發(fā)生，黃石學(xué)校避雷針安裝，放電電流主要通過避雷針流入大地，因此，不會打在房屋或附近人的身上，只會打在避雷針上了，黃石學(xué)校避雷針安裝。由此可見，避雷針的前列放電作用會減少地面物與云之間打雷的可能性；到了不可避免時(shí)，它自己就負(fù)擔(dān)了雷的打擊，房屋與人得到了安全。</span>

15～20mm、長度為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。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百的電荷。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)云層上度電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成問為導(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，使其不對高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。帶電的云，首先是從上往下運(yùn)行,在高處安避雷針，就首先將云中的電放答掉,以后到房子接觸云的時(shí)候，就基本沒有或只有少部分電而沒有危險(xiǎn)了</span>

style="font-size:16px;">安裝避雷針必須遵守中華人民國家標(biāo)準(zhǔn)（GB50057—94）《建筑物防雷設(shè)計(jì)規(guī)范》，具體施工必須嚴(yán)格遵循國家標(biāo)準(zhǔn)（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗(yàn)收規(guī)范，雷雨日不可進(jìn)行避雷針的安裝和檢測。 ① 定貨時(shí)請告知您所選用的避雷針（塔）桿的技術(shù)參數(shù)，以便廠方給您選配更規(guī)范的互連過渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當(dāng)其厚度不小于4mm時(shí)，可作避雷針的引下線。筒體底部應(yīng)有兩處與接地體對稱連接。 ③ 建筑物L(fēng)的防雷設(shè)施采用多根引下線時(shí)，宜在各引下線距地面的1.5～1.8m處設(shè)置斷接卡，斷接卡應(yīng)加絕緣保護(hù)措施。容 ④ 避雷針與引下線之間的連接應(yīng)采用焊接。 ⑤ 避雷針其接地裝置，應(yīng)采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥

style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應(yīng)雷電和綜合性防雷電。防直擊雷電的避雷裝置一般由三部分組成，即接閃器、引下線和接地體；接閃器又分為避雷針、避雷線、避雷帶、避雷網(wǎng)。以避雷針作為接閃器的防雷電原理是：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(qiáng)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(qiáng)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(dá)到避雷效果。實(shí)際上，避雷針是引雷針，可將周圍的雷電引來并提前放電，將雷電電流通過自身的接地導(dǎo)體傳向地面，避免保護(hù)對象直接遭雷擊。</span>

因?yàn)楸芾揍樛ㄟ^引下線與接地裝置相連接。雷電流擊在避雷針上，其能量通過引下線迅速到達(dá)接地裝置，在大地中消除，使被保護(hù)物不會受抄到破壞。避雷針，又名防雷針，是用來保護(hù)建筑物、高大樹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。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。當(dāng)雷云放電接近地面時(shí)它使地面電場發(fā)生畸變。在避雷針的頂端，形成局部電場集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針放電，再通過接地引下線和接地裝置將雷電流引入大地，從而使被保zd護(hù)物體免遭雷擊。</span>

style="font-size:16px;">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。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。 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(gè)尖頭或分叉為幾個(gè)尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時(shí)。 2、避雷針的前列因靜電感應(yīng)就集中了異種電荷，發(fā)生前列放電，與云內(nèi)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(shí)來不及按上述方式中和，于是有強(qiáng)烈的放電，加雷電仍會發(fā)生。</span> 黃石學(xué)校避雷針安裝</p><p
