1、直接雷擊的危害大(尤其會損壞建筑) 品質(zhì)好的防雷接地工程一定要考慮直擊雷，直接雷擊是指地面上的人、動物、建筑物、電氣設(shè)備等直接被雷電擊中。發(fā)生直接雷擊時，特大的雷電流(幾十至幾百千安)會通過被擊物，并在被擊物的內(nèi)部產(chǎn)生高達幾萬度的溫度，并引起使被擊物燃燒起火，架空導(dǎo)線溶化等雷擊后果,防雷接地工程勢在必行。</span> </p> <p> <span style="font-size:16px;"> 2、感應(yīng)雷的危害（嚴(yán)重的影響低壓系統(tǒng)）當(dāng)雷云對地放電時，雷擊點主放電的過程中，位于雷擊點附近的導(dǎo)線上將產(chǎn)生感應(yīng)過電壓。的防雷接地工程公司介紹，一般情況下，過電壓幅值可達幾十萬伏至幾百萬伏，它能使電力設(shè)備絕緣，并且發(fā)生閃絡(luò)或擊穿，咸寧接地防雷設(shè)施檢測，造成電力系統(tǒng)停電，電力設(shè)備的絕緣損壞，咸寧接地防雷設(shè)施檢測，會使高電壓竄入低壓系統(tǒng)，這將對低壓用電設(shè)備和人員的安全造成極大的威脅，咸寧接地防雷設(shè)施檢測，還可能發(fā)生火災(zāi)和，所以防雷接地工程勢在必行。 3、雷電侵入波的危害極大（主危害架空線路）我們來分析一下不同類型雷擊的危害，這樣以便于為防雷接地工程的開展做前期鋪墊和參考依據(jù)。</span> 專業(yè)機房防雷，乾元上風(fēng)防雷。咸寧接地防雷設(shè)施檢測</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

1：可減少電器設(shè)備的損壞在郵電或廣電及金融及電力等重要的領(lǐng)域內(nèi)防雷是必不可少的，使用防雷產(chǎn)品不但可以有效的保護好所有電力設(shè)備使用的安全性，并能有效的規(guī)避感應(yīng)雷電沿著各信號線及電源線侵入到電器內(nèi)部，造成電器設(shè)備的損傷或損壞以至縮短各電器設(shè)備的使用壽命，嚴(yán)重的還會直接燒壞或擊毀重要的電器電力設(shè)備造成整個工程的癱瘓。因此使用防雷產(chǎn)品可以減少電器設(shè)備的損壞有效的將雷電流接地保護。 2：可保護人員的安全通過安裝使用防雷產(chǎn)品可以使設(shè)備與線路或大地形成一個有條件的等位電體，可以有效的將雷電流進行阻攔并且通過接地放電，因此可以有效的保障人身的安全，不會讓雷擊引起人身的安全問題也能杜絕大量的雷電泄入大地產(chǎn)生大量的電流。 3：降低各企業(yè)的經(jīng)濟損失眾所周知當(dāng)雷電感應(yīng)嚴(yán)重的情況下雷電波的侵襲會產(chǎn)生非常大的破壞力，因此一旦受到雷電的危害就會引發(fā)很嚴(yán)重的，對于各企業(yè)特別是工廠的電子或電氣設(shè)備將會有特別大的影響。</span> 潛江機房防雷公司電話醫(yī)院防雷找——

style="font-size:16px;">（一）、不能停留在樓頂上，站在樓頂極易招惹雷擊。注意關(guān)閉門窗。關(guān)閉門窗，阻隔空氣運動途徑，能阻止球雷入室。</span> </p> <p> <span style="font-size:16px;">（二）、不宜使用花灑沖涼。若是建筑物發(fā)生雷擊現(xiàn)象時，巨大的雷電流有可能沿著水流導(dǎo)致淋浴者遭雷擊傷亡。</span> </p> <p> <span style="font-size:16px;">（三）、不要觸摸金屬管道，這些金屬導(dǎo)體若接地不良，雷電流有可能以這些導(dǎo)體通過空氣向人體放電。</span> </p> <p> <span style="font-size:16px;">（四）、不宜靠近建筑物的外墻以及電氣設(shè)備。應(yīng)停留在離電力線以及跟它們相連接的電氣設(shè)備1米遠的地方。</span> </p> <p> <span style="font-size:16px;">（五）、不宜進入低矮建筑物。由于這些低矮的建筑物沒有防雷設(shè)施且大都處在曠野中，遭受雷擊的概率特別高。當(dāng)暴風(fēng)雨即將來臨，而又處在開闊地帶、山坡、河邊時，可選擇一些高大物體或架空電力線保護的區(qū)域，但所處的位置應(yīng)距電線桿或高大物體2米以上。</span> </p> <p> <span style="font-size:16px;">（六）、不宜躲在大樹底下。如果萬不得已需要在大樹底下停留，則必須與樹身和枝椏保持2米以上的距離，并且盡可能下蹲并把雙腳先靠攏。</span> </p> <p> <span style="font-size:16px;">（七）、不宜在曠野高打雨傘等物體。在近雷暴天氣條件下，不僅高打雨傘容易遭雷擊，就是高舉羽毛球拍、高爾夫球棍、鐵鍬、鋤頭等物體都會帶來雷擊的危險。</span> </p> <p> <br /> </p> </p><p> <span style="font-size:16px;">防雷市場的發(fā)展現(xiàn)狀</span> </p> <p> <span style="font-size:16px;">雷電造成的危害分為直擊雷害和感應(yīng)雷害。直擊雷害是指由于閃電直接擊中目標(biāo)物;感應(yīng)雷害是指在雷電放電過程中，由于強大的雷擊電磁脈沖(LEMP)—直擊雷產(chǎn)生的場效應(yīng)(感應(yīng))—對附近的電子設(shè)備、通訊設(shè)備等產(chǎn)生的破壞，這種災(zāi)害往往造成嚴(yán)重的經(jīng)濟損失，也是經(jīng)濟發(fā)達地區(qū)雷電災(zāi)害的主要形式。</span> </p> <p> <span style="font-size:16px;">防雷市場的地理分布與雷暴日的多少密切相關(guān)。雷擊較頻繁的南方地區(qū)是防雷產(chǎn)品的主要市場，尤其是海南省、廣東省、***、福建省、貴州省等省份，對防雷的需求旺盛;從地區(qū)經(jīng)濟差異來看，經(jīng)濟較發(fā)達的地區(qū)的防雷產(chǎn)品應(yīng)用比例明顯高于經(jīng)濟欠發(fā)達地區(qū)；從區(qū)域市場特點來看，南方防雷市場比北方大，但南方防雷廠商較多，競爭較為激烈，現(xiàn)在一些南方發(fā)達地區(qū)的二三級城市的防雷應(yīng)用都已經(jīng)比較普及；北方防雷市場主要集中在京、津、冀及其周邊地區(qū)，少部分品牌滲透到了縣級城市；東北、山西、內(nèi)蒙以及西部的大部分地區(qū)受雷暴日較低因素的影響防雷市場空白較多。</span>

style="font-size:16px;">防雷器內(nèi)部受潮是一種比較常見的故障現(xiàn)象。具體表現(xiàn)是絕緣電阻低于2500MΩ，工頻放電電壓下降。 1)防雷器頂部緊固螺母松動導(dǎo)致漏水;瓷套頂部密封用螺栓的墊圈沒有焊死，密封墊圈長時間使用后會發(fā)生老化，潮氣、水分沿螺釘縫滲入內(nèi)腔也就不足為奇了。 2)底部密封試驗的小孔沒有焊牢或者是沒有防雷器內(nèi)部受潮故障的原因及表現(xiàn)堵死導(dǎo)致水分或者是水蒸氣趁虛而入。 3)瓷套破裂、有、砂眼、裙邊膠合處有裂縫等等許多因素都會導(dǎo)致潮氣及水分進入。 4)橡膠墊圈長時間使用老化開裂，失去密封作用。 5)底部壓緊用的扇形鐵片留有縫隙，沒有塞緊，底部密封橡膠墊圈位置不正，造成空隙滲入潮氣。 6)瓷套與法蘭膠合處不平整或瓷套有裂紋。</span> 技術(shù)先進防雷公司，乾元上風(fēng)防雷。潛江機房防雷公司電話</p><p style="text-indent:25px">天然氣站防雷，乾元上風(fēng)防雷。咸寧接地防雷設(shè)施檢測</p><h2> 防雷公司談高層防雷的措施——乾元上風(fēng)防雷 </h2> <p> <span style="font-size:16px;">在一定定范圍內(nèi)，越高的建筑，越具有受雷擊的可能性。在通常情況下，高層住宅樓都是安裝有避雷針的，不會發(fā)生雷擊。但是在下列情況下也會受到雷電的危害，下面湖北防雷公司來為大家介紹一下。避雷針的保護范圍一般是指直擊雷所能保護到的空間而言。只要在它的保護范圍以內(nèi)，如果避雷針始終保持良好，建筑物就可以不遭受直接雷擊。避雷針的保護范圍，取決于建筑物的高度和體型，特別是避雷針本身的高度或避雷針裝有建筑物上的總高度。一般說來避雷針裝得越高，或避雷針本身越高，它的保護范圍就越大。避雷針的保護范圍往往通過計算來決定。簡言之，單支避雷針采用45度角的保護范圍，其地面的保護半徑等于針高的1.5倍。避雷針的接地電阻值過高或接地導(dǎo)線受到機械損傷或腐蝕時。高層住宅的電話線、電燈線安裝距離避雷針及其接地導(dǎo)線過近時。電視天線塔、廣告牌、旗桿高于避雷針而無**的避雷接地系統(tǒng)時。雷雨天收看電視或開窗賞雨景時。雷雨天在樓頂上作業(yè)時。高層住宅須安裝避雷針。每年入夏之前，必須對避雷設(shè)備進行檢查。</span>
