style="font-size:16px;">1、避雷針，又名防雷針、接閃桿，是用來保護建筑物、高大樹木等避免雷擊的裝置。在被保護物頂端安裝一根接閃器，用符合規(guī)格導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標準，每一個防雷類別需要的避雷針高度規(guī)格都不一樣，潛江建筑避雷針。 2、當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，以影響雷電先導放電的發(fā)展方向，引導雷電向避雷針放電，再通過接地引下線和接地裝置將雷電流引入大地，從而使被保護物體免遭雷擊。 3、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電性。一旦有一處聯(lián)接不好，或斷了，潛江建筑避雷針，斷口以上的一段就成為一個隔離的導電系統(tǒng)。 4、當云中有電荷時，這隔出的部分上部感應(yīng)出與云中電異號的電荷，而下部感應(yīng)出與云中電同號的電荷，如果上部和云中電起放電作用時，強大的放電電流只能通過建筑物放出大量熱量，于是引起雷擊。這樣不但不能避雷，反而還招來雷禍。為防意外，高大建筑物豎起幾條避雷針，潛江建筑避雷針。另外，每一又避雷針只能保護一定的建筑面積。對于較大的建筑物也需要豎起幾條避雷針。</span>

1、所有金屬部件必須鍍鋅，操作時注意保護鍍鋅層。 2、采用鍍鋅鋼管管制作針尖，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、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 5、圓鋼為其直徑的6倍。 6、圓鋼與扁鋼連接時，其長度為圓鋼直徑的6倍。 7、避雷針一般采用圓鋼或鋼管制成，其直徑不應(yīng)小于下列數(shù)值： **避雷針一般采用直徑為19mm鍍鋅圓鋼；屋面上的避雷針采用直徑25mm鍍鋅鋼管；水塔頂部避雷針采用直徑25mm或40mm的鍍鋅鋼管；囪頂上避雷針采用直徑25mm鍍鋅圓鋼或直徑為40mm鍍鋅鋼管e避雷環(huán)用直徑12mm鍍鋅圓鋼或截面為100mm2鍍鋅扁鋼，其厚度應(yīng)為4mm。</span>

style="font-size:16px;">避雷針通過導線接入地下，與地面形成等電位差，利用自身的高度，使電場強度增加到極限值的雷電云電場發(fā)生畸變，開始電離并下行先導放電；避雷針在強電場作用下產(chǎn)生前列放電，形成向上先導放電；兩者會合形成雷電通路，隨之瀉入大地，達到避雷效果。常用避雷針保護范圍的計算方法主要有折線法和滾球法。“折線法”的主要特點是設(shè)計直觀，計算簡便，可節(jié)省投資，但不適用于高度大于20m的建筑物；“滾球法”的主要特點是可以計算避雷針或避雷帶與網(wǎng)格組合時的保護范圍。（詳細知識可以咨詢湖北乾元上風電氣工程有限公司）湖北乾元上風電氣工程有限公司堅持“安全為先、服務(wù)為先、信譽為先”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。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，做到科學設(shè)計、科學施工，多方面、安全、合理、經(jīng)濟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工作。以更好的工程質(zhì)量和服務(wù)態(tài)度回報社會及廣大客戶的信任與厚愛</span>。 </p><h2> 建筑物在多少高度必須安裝避雷針 </h2> <p> <span style="font-size:16px;">并不是規(guī)定有多少層需要裝避雷針，要看樓房是不是在避雷帶保護半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個51層的樓房上裝了避雷針，如果樓房在避雷針保護半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當?shù)氐狞c，附近也有沒有裝避雷針，這樣也需要裝避雷針。避雷針的種類：直擊雷避雷針/特殊避雷針/提前預(yù)放電避雷針 1、直擊雷適用于石化倉庫、廣播電視、加油站、建筑大樓、信標臺，通信基站、氣象臺、基地、雷達機房、銀行大樓。 2、特殊適用于較高的建筑大樓微波通訊站、雷達基站、信標臺，通信基站、基地、雷達機房、銀行大樓、天文氣象臺等重要場所。 3、預(yù)放電當避雷針截受雷擊時，由接閃體接閃，通過雷電波形處理裝置，利用外殼與中心接地桿之間有3mm間隙，構(gòu)成耦合電容，同時外殼通過一個電感線圈接地（中心接地桿）當下行先導接近接閃器時，由于頻率極高，電感呈開路狀態(tài)，電容對高頻呈現(xiàn)短路特性。因此耦合電容作用下，接閃器表面電場強度迅速增加，直至觸發(fā)雪崩過程，從而能在頃刻間將雷電流泄放入地，以至有效的達到防雷害保安全的目的。</span>

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，甚至還會造成人員傷亡，嚴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”,其實遠遠比防暑更重要! 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，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，插座是一個防雷關(guān)口，要保護電器不被雷擊損害，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，它自己就負擔了雷的打擊，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電系統(tǒng)。</span>
