style="font-size:16px;">家中是否也要安裝避雷針據(jù)調(diào)查，雷擊對電子電器設(shè)備的損壞始終高居雷電傷害榜*位，由雷電所引發(fā)的家用電器壽命降低、故障不斷、擊毀擊壞等情況越來越普遍，襄陽塔頂避雷針安裝公司，甚至還會造成人員傷亡，嚴(yán)重威脅到人們的財產(chǎn)和生命安全。因此，防止家電夏季被“雷”,其實遠(yuǎn)遠(yuǎn)比防暑更重要! 避雷針其實不“避雷” 通常情況下，城市建筑一般都會安裝避雷針，襄陽塔頂避雷針安裝公司，許多人以為有了避雷針，就可以不用再操心“防雷”問題，事實上并非如此! (遭遇雷擊后的電視機(jī)殘骸) 雷電有直擊雷和感應(yīng)雷之分。在家用電器的使用過程中，襄陽塔頂避雷針安裝公司，插座是一個防雷關(guān)口，要保護(hù)電器不被雷擊損害，就一定要使用具備防雷功能的專業(yè)插座。目前，市面上的一些防雷插座存在著較嚴(yán)重的質(zhì)量問題，如防雷技術(shù)不成熟;使用質(zhì)量低劣(三無產(chǎn)品:無廠家、無參數(shù)、無證書)的防雷元器件;未經(jīng)專業(yè)防雷檢測機(jī)構(gòu)的檢驗……等等，不僅防雷性能無法得到保證，甚至還存在更大的安全。</span>

style="font-size:16px;">在雷雨天氣，高樓上空出現(xiàn)帶電云層時，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，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電容器，由于它較尖，即這個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)云層上電荷較多時，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，使其不對高層建筑構(gòu)成危險，保證了它的安全。</span>

因為避雷針通過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> </p><h2> 避雷針是啥材料做的？ </h2> <p> <span style="font-size:16px;">有什么要求？ 1、所有金屬部件必須鍍鋅，操作時注意保護(hù)鍍鋅層。 2、采用鍍鋅鋼管管制作針尖知，管壁厚度不得小于3mm,針尖刷錫長度不得小于70mm 3、避雷針應(yīng)垂直安裝牢固。垂直度允許偏差為3/1000。 4、焊接要求焊接應(yīng)采用搭接焊，其搭接長度必須符合下列規(guī)定： 5、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 6、圓鋼為其直徑的6倍。 7、圓鋼與扁鋼連接時，其長度為圓鋼直徑的6倍。湖北乾元上風(fēng)電氣工程有限公司堅持“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、注重實效”的原則貫穿于各項工程的設(shè)計和施工。</span> 防雷避雷針安裝公司，湖北乾元上風(fēng)電氣供應(yīng)。</p><div style="width:100%;text-align:

<span style="font-size:16px;">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尖頭或分叉為幾個尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時。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，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。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，它自己就負(fù)擔(dān)了雷的打擊，房屋與人得到了安全。由于避雷針的構(gòu)造和作用，我們要特別注意保持避雷針的良好導(dǎo)電性。一旦有一處聯(lián)接不好，或斷了，斷口以上的一段就成為一個隔離的導(dǎo)電系統(tǒng)。</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的“避雷針”，它通過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，所以避雷針實際是引雷針。它將雷電吸引至自身，使雷電通過引下線至接地裝置而泄放到大地上，從而使保護(hù)對象免遭雷擊。現(xiàn)代避雷針是美國科學(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，他在1752年7月的一個雷雨天，冒著被雷擊的危險，和他的兒子一起，做了一個歷史上非常的雷電實驗。他將一個系著長長金屬導(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，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。幸虧這次傳下來的閃電比較弱，富蘭克林沒有受傷。這次試驗非常成功，讓富蘭克林充分認(rèn)識了雷電的性質(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來。</span>
