</p><h2> 避雷針的作用 </h2> <p> <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度相對較大，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，使雷電流通過引下線至接地裝置而泄放大地，從而使保護對象免遭雷擊。避雷針的保護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，其保護范圍也隨之?dāng)U大，達到一定高度以后，其保護范圍就不再擴大了。避雷針的高度是這樣確定的：對于類、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，既浪費又無實際效果。</span>

style="font-size:16px;">安裝避雷針必須遵守中華人民國家標(biāo)準（GB50057—94）《建筑物防雷設(shè)計規(guī)范》，具體施工必須嚴格遵循國家標(biāo)準（GB 50169—92）電氣裝置安裝工程接地裝置施工及驗收規(guī)范，雷雨日不可進行避雷針的安裝和檢測。 ① 定貨時請告知您所選用的避雷針（塔）桿的技術(shù)參數(shù)，以便廠方給您選配更規(guī)范的互連過渡接頭安裝附件。 ② 裝有避雷針的金屬筒內(nèi)體，當(dāng)其厚度不小于4mm時，可作避雷針的引下線。筒體底部應(yīng)有兩處與接地體對稱連接。 ③ 建筑物L(fēng)的防雷設(shè)施采用多根引下線時，宜在各引下線距地面的1.5～1.8m處設(shè)置斷接卡，斷接卡應(yīng)加絕緣保護措施。容 ④ 避雷針與引下線之間的連接應(yīng)采用焊接。 ⑤ 避雷針其接地裝置，應(yīng)采取自下而上的施工程序。首先安裝集中接地裝置，后安裝引下線，安裝避雷針。 ⑥ 安裝時請勿觸摸主接閃前列、主動放電前列。 ⑦ 產(chǎn)品設(shè)計使用壽命20年。</span> 避雷針安裝價格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)優(yōu)良值得推薦！孝感小區(qū)避雷針加工廠家</p><p style="text-indent:25px">避雷針價格，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保障！仙桃信號避雷針檢測</p><h2> 避雷針又稱引雷針 </h2> <p> <span style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應(yīng)雷電和綜合性防雷電。防直擊雷電的避雷裝置一般由三部分組成，即接閃器、引下線和接地體；接閃器又分為避雷針、避雷線、避雷帶、避雷網(wǎng)。以避雷針作為接閃器的防雷電原理是：避雷針通過導(dǎo)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(dǎo)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(dǎo)放電；兩者會合形成雷電通路，隨之瀉入大地，達到避雷效果。實際上，避雷針是引雷針，可將周圍的雷電引來并提前放電，將雷電電流通過自身的接地導(dǎo)體傳向地面，避免保護對象直接遭雷擊。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(xué)設(shè)計、科學(xué)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>
