style="font-size:16px;">避雷針是由美國(guó)科學(xué)家富蘭克林發(fā)明的富蘭克林在研究閃電與人工摩擦產(chǎn)生的電的一致性時(shí)，他就從兩者的類比中作出過(guò)這樣的推測(cè)：既然人工產(chǎn)生的電能被前列吸收，那么閃電也能被前列吸收。他由此設(shè)計(jì)了風(fēng)箏實(shí)驗(yàn)，而風(fēng)箏實(shí)驗(yàn)的成功反過(guò)來(lái)又證實(shí)了他的推測(cè)。他由此設(shè)想，若能在高物上安置一種前列裝置，就有可能把雷電引入地下。富蘭克林把一根數(shù)米長(zhǎng)的細(xì)鐵棒固定在高大建筑物的頂端，在鐵棒與建筑物之間用絕緣體隔開(kāi)，仙桃機(jī)房避雷針安裝廠家，仙桃機(jī)房避雷針安裝廠家。然后用一根導(dǎo)線與鐵棒底端連接。再將導(dǎo)線引入地下。富蘭克林把這種避雷裝置稱為避雷針，仙桃機(jī)房避雷針安裝廠家。經(jīng)過(guò)試用，果然能起避雷的作用。</span>

style="font-size:16px;">避雷針是保護(hù)建筑物等避免雷擊的裝置。在高大建筑物頂端安裝一個(gè)金屬棒，用金屬線與埋在地下的一塊金屬板連接起來(lái)，利用金屬棒的前列放電，使云層所帶的電和地上的電逐漸中和。唐代《炙轂子》一書在記載了這樣一件事：漢朝時(shí)柏梁殿遭到火災(zāi)，一位巫師建議，將一塊魚尾形狀的銅瓦放在層頂上，就可以主防止雷電所引起的天火。屋頂上所設(shè)置的魚尾開(kāi)頭的瓦飾，實(shí)際上兼作避雷之用，可認(rèn)為是現(xiàn)代避雷針的雛形。而早在以前，中國(guó)已經(jīng)有了避雷針，一般以**為裝飾，龍嘴里有避雷針頭。法國(guó)旅行家卡勃里歐別·戴馬甘蘭1688年所著的《中國(guó)新事》一書中記有：中國(guó)屋脊兩頭，都有一個(gè)仰起的**，龍口吐出曲折的金屬舌頭，伸向天空，舌根連結(jié)一根細(xì)的鐵絲，直通地下。這種奇妙的裝置，在發(fā)生雷電的時(shí)刻就大顯神通，若雷電擊中了屋宇，電流就會(huì)從龍舌沿線睛行至地底，避免雷電擊毀建筑物。這說(shuō)明，中國(guó)古代建筑上的如雷裝置，在大批量和結(jié)構(gòu)上已和現(xiàn)代避雷針基本相似。</span>

style="font-size:16px;">防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是大家通常所說(shuō)的“避雷針”，它通過(guò)引下線和接地裝置與大地相連。避雷針高高聳立，高于被保護(hù)的所有物體，與雷云的距離近，所以，它易吸引雷電，雷電通過(guò)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，使雷電通過(guò)引下線至接地裝置而泄放到大地上，從而使保護(hù)對(duì)象免遭雷擊。現(xiàn)代避雷針是美國(guó)科學(xué)家富蘭克林發(fā)明的。富蘭克林認(rèn)為閃電是一種放電現(xiàn)象。為了證明這一點(diǎn)，他在1752年7月的一個(gè)雷雨天，冒著被雷擊的危險(xiǎn)，和他的兒子一起，做了一個(gè)歷史上非常的雷電實(shí)驗(yàn)。他將一個(gè)系著長(zhǎng)長(zhǎng)金屬導(dǎo)線的風(fēng)箏放飛進(jìn)雷雨云中，在金屬線末端拴了一串銅鑰匙。當(dāng)雷電發(fā)生時(shí)，富蘭克林手接近鑰匙，鑰匙上迸出一串電火花，手上還有麻木感。幸虧這次傳下來(lái)的閃電比較弱，富蘭克林沒(méi)有受傷。這次試驗(yàn)非常成功，讓富蘭克林充分認(rèn)識(shí)了雷電的性質(zhì)，并由此發(fā)明了避雷針，首先在自己費(fèi)城的住宅安裝了避雷針。此后，避雷針便在世界上流行開(kāi)來(lái)。</span>

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(shù)冠和樹(shù)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(zhǎng)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(shù)皮，仿生樹(shù)根做隱蔽，固定時(shí)不能傷害到樹(shù)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(cè)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(shù)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(wú)污染導(dǎo)電性能好，距離樹(shù)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(cè)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(shù)名木！</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(lái)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(shuō)，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?gòu)健⑷?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(wèn)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(lái)說(shuō)，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)有保障！潛江小區(qū)避雷針安裝廠家</p><p
