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)，十堰橋梁避雷針安裝廠家，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，十堰橋梁避雷針安裝廠家，十堰橋梁避雷針安裝廠家，避雷針大多建設(shè)在35米-45米之間。</span> 防雷避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！十堰橋梁避雷針安裝廠家</p><div

1）避雷針要采用捷力通防側(cè)閃電的玻璃鋼材質(zhì)，高度根據(jù)樹冠和樹高滾球半徑法計(jì)算，可以加裝一支玻璃鋼避雷針，兩支避雷針到多支玻璃鋼避雷針！避雷針固定要考慮長久性穩(wěn)定性！ 2）引下線敷設(shè)不能影響美觀，比如采用仿生樹皮，仿生樹根做隱蔽，固定時(shí)不能傷害到樹干，雷電計(jì)數(shù)器則是為了記錄雷擊環(huán)境，做重點(diǎn)雷電檢測防護(hù)。 3）防雷接地同樣也很重要：不能用有污染的接地材料，不能破壞樹根等，方案采用零歐復(fù)合接地材料，零歐復(fù)合接地體壽命可試用百年以上，不腐蝕無污染導(dǎo)電性能好，距離樹干三米外為宜，采用深井接地系統(tǒng)施工！特殊地方采用地埋式接地電阻測試儀器，雷電峰值記錄儀器等！采用科學(xué)的雷電防護(hù)措施保護(hù)每一顆古樹名木！</span> </p><h2> 避雷針安裝注意事項(xiàng) </h2> <p> <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(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> 防雷避雷針安裝公司，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！</p><div

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)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。湖北乾元上風(fēng)電氣工程有限公司堅(jiān)持“安全為先、服務(wù)為先、信譽(yù)為先”的經(jīng)營宗旨，并以“質(zhì)量至上、注重實(shí)效”的原則貫穿于各項(xiàng)工程的設(shè)計(jì)和施工。我們以質(zhì)量的技術(shù)力量和良好的服務(wù)態(tài)度為您的防雷工程提供多方面的解決方案和技術(shù)支持，做到科學(xué)設(shè)計(jì)、科學(xué)施工，多方面、安全、合理、經(jīng)濟(jì)的做好各類防雷建筑物的雷電防御及設(shè)備和人身的安全防護(hù)工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報(bào)社會(huì)及廣大客戶的信任與厚愛。防雷避雷針廠家，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良！黃石機(jī)房避雷針安裝廠家</p><p
