style="font-size:16px;">在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，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(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，鄂州變電站避雷針廠家排名。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。帶電云層與避雷針形成通路，而避雷針又是接地的，鄂州變電站避雷針廠家排名，避雷針就可以把云層上的電荷導(dǎo)入大地，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，鄂州變電站避雷針廠家排名、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。</span>

style="font-size:16px;">再也不怕打雷了防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是通常所說的''避雷針''，它通過引下線和接地裝置與大地相連。由于''前列放電''效應(yīng)，大地被感應(yīng)出的電荷易聚集在針尖處，使得雷云與避雷針附近空間的電場強(qiáng)度相對(duì)較大，空氣也容易被擊穿，雷電流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(shí)際是引雷針。它將雷電吸引至自身，使雷電流通過引下線至接地裝置而泄放大地，從而使保護(hù)對(duì)象免遭雷擊。避雷針的保護(hù)范圍可用滾球法來確定。在一定范圍內(nèi)，隨著避雷針的增高，其保護(hù)范圍也隨之?dāng)U大，達(dá)到一定高度以后，其保護(hù)范圍就不再擴(kuò)大了。避雷針的高度是這樣確定的：對(duì)于類、第二類和第三類防雷建筑物，避雷針的有效高度分別為30米、45米和60米，所以盲目增加避雷針高度，既浪費(fèi)又無實(shí)際效果。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452432724610/5832678.jpg"></div><h2> 裝置避雷針是避免雷擊的有效方法。 </h2> <p> <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(gè)尖頭或分叉為幾個(gè)尖頭。有了這樣的裝置，當(dāng)空中有帶電的云時(shí)。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(shí)來不及按上述方式中和，于是有強(qiáng)烈的放電，加雷電仍會(huì)發(fā)生。但這時(shí)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(hào)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(huì)打在房屋或附近人的身上，只會(huì)打在避雷針上了。由此可見，避雷針的前列放電作用會(huì)減少地面物與云之間打雷的可能性；到了不可避免時(shí)，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(gè)隔離的導(dǎo)電系統(tǒng)。</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(hù)半徑之內(nèi)。就是說房子如果50層，旁邊如果也有一個(gè)51層的樓房上裝了避雷針，如果樓房在避雷針保護(hù)半徑之內(nèi)，也可以不用裝。如果房子只有三層，但是在當(dāng)?shù)氐狞c(diǎn)，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(biāo)臺(tái)，通信基站、氣象臺(tái)、基地、雷達(dá)機(jī)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(dá)基站、信標(biāo)臺(tái)，通信基站、基地、雷達(dá)機(jī)房、銀行大樓、天文氣象臺(tái)等重要場所。 3、預(yù)放電當(dāng)避雷針截受雷擊時(shí)，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(shí)外殼通過一個(gè)電感線圈接地（中心接地桿）當(dāng)下行先導(dǎo)接近接閃器時(shí)，由于頻率極高，電感呈開路狀態(tài)，電容對(duì)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(qiáng)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(dá)到防雷害保安全的目的。</span>

style="font-size:16px;">所謂雷電現(xiàn)象，就是空中云層積累的電荷達(dá)到頗大數(shù)量時(shí)，它與附近的帶電云層或物體間產(chǎn)生很大的電勢差，形成很強(qiáng)的電場，兩部分異性電荷突破周圍空氣的阻礙去中和，發(fā)生強(qiáng)烈放電，這時(shí)在電通過的路徑上發(fā)出聲和光，就是雷電。雷電通常發(fā)生在不同的云塊之間，或云的下部與地面物之間。我們要避免的只是云和地或地上物之間的雷電。如果這塊云的上部帶正電，下部帶負(fù)電，則地面上感應(yīng)出來的電是正電，此時(shí)地面上的凸出物（房屋、樹或人體）就有可能與云中電荷發(fā)生放電現(xiàn)象，遭到雷擊的災(zāi)禍</span>
