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(cè)。 ① 定貨時(shí)請(qǐng)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(duì)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 安裝時(shí)請(qǐng)勿觸摸主接閃前列、主動(dòng)放電前列。 ⑦ 產(chǎn)品設(shè)計(jì)使用壽命20年。</span> 咸寧變電站避雷針安裝廠家防雷避雷針，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！</p><div style="width:100%;text-align: center;"><img style="max-width:

——★1避雷針是利用前列放電的原理，吸收雷電達(dá)到保護(hù)復(fù)作用。避雷針是保護(hù)某一片區(qū)域的，所以設(shè)置高度很高（具體高度，需要根據(jù)保護(hù)面積作復(fù)雜的計(jì)算），并且要有很高的強(qiáng)度要求，可以很好的吸收【直擊雷】的放電。 ——★2、建筑物避雷帶的避雷原理同避雷針相同，但是： ①、保護(hù)目的為建筑物自己，因此不制需要特別的高度等質(zhì)量要求； ②、一般的建筑物遭受直擊雷的可能性極低（高層建筑除外），主要防止【感應(yīng)雷】對(duì)建筑物的損害，一百般避雷帶足以滿足要求。 ——★3、直擊雷與感應(yīng)雷的區(qū)別： ①、直擊雷就是雷電直接與地面物體放電，釋放能量； ②、距離帶電云彩較近的建筑物，會(huì)度積聚與帶電云彩相反極性的、相同數(shù)量的電荷，當(dāng)帶電云彩突然失去電荷（如云彩之間放電），積聚在建筑物上的電荷就失去吸引力而四處泄放，這就是感應(yīng)雷。對(duì)于避雷針的材料，有很多種</span> </p><h2> 避雷針的保護(hù)范圍是多少？ </h2> <p> <span style="display:none;"></span><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(shí)把雷電流泄入大地，起著保護(hù)其附源近比它矮的建筑物或設(shè)備免受雷擊的作用。簡(jiǎn)單一點(diǎn)說，一級(jí)保護(hù)是以30米為半徑、二級(jí)保護(hù)是45米為半百徑、三級(jí)保護(hù)是60米為半徑做弧的保護(hù)范圍。計(jì)算方法避雷針的保護(hù)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(hù)范圍采用規(guī)范之計(jì)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(hù)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(hù)物的高度一般來說，避雷針越高，保護(hù)范圍就越大，保護(hù)效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟(jì)答性，避雷針大多建設(shè)在35米-45米之間。</span> 避雷針廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！</p><div style="width:100%;text-align:

style="font-size:16px;">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。按我國統(tǒng)計(jì)的雷電流幅值約為300 kA，其對(duì)應(yīng)的雷擊高度為408 m。取雷擊定位高度為400m，可得出不同高度避雷針的保護(hù)區(qū)和散擊區(qū)的地表半徑見表1。我國舊式民房一般高度在10 m以下，避雷帶和避雷網(wǎng)的高度與房高相同，安裝的短針防雷其高度為1～2 m，它們引起的散擊現(xiàn)象不明顯；高聳建筑物和高架避雷針引雷招致雷擊率增高和存在散擊區(qū)。</span>
