</h2> <p> <span style="font-size:16px;">1、避雷針——直接接地。利用電荷前列放電現象不讓雷擊發(fā)生。避雷針和被保護物體是分開的，可以保護比較集中的重要物體。 2，潛江醫(yī)院避雷針安裝、避自雷器——間接接地。利用過電壓放電現象讓雷擊電壓通過避雷器進入大地。避雷器和被保護物體是連接的，可以保護帶電物體，如輸電線路。避雷器工作原理：避雷器實百際上是一種非線性極好的電阻，在高電壓下電阻很小，在低電壓下電阻很高，作用類似于穩(wěn)壓度二極管。目前避雷器一般為氧化鋅避雷器，潛江醫(yī)院避雷針安裝，主要元件為問氧化鋅閥片。避雷器在電力系統(tǒng)中與被保護設備并聯，潛江醫(yī)院避雷針安裝，正常時泄漏電流很小，不影響系統(tǒng)運行。當系統(tǒng)有過電壓時（即超過正常運行電壓的高電壓），避雷器即呈現低電阻泄放答能量，同時限制系統(tǒng)電壓的幅值，確保電氣設備的絕緣不被擊穿。</span>

style="font-size:16px;">避雷，實際上是引雷德作用原理：在雷雨天氣，高樓上空出現帶電云層時，迅雷針和高樓頂知部都被感應上大量電荷，由于避雷針針頭是尖的，而靜電感應時，導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道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，當云層上電荷較多時，避雷針與云層之版間的空氣就很容易被擊穿，成為導體．這樣，帶電云層與避雷針形成通路，而避雷針又是接地的．避雷針就可以權把云層上的電荷導人大地，使其不對高層建筑構成危險，保證了它的安全。</span> 襄陽塔頂避雷針生產廠家防雷避雷針廠家，湖北乾元上風電氣供應，歡迎您來點電咨詢！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="潛江醫(yī)院避雷針安裝,避雷針"

(1)接地體頂面埋設深度應符合設計要求。當無要求時，不應小于0.6m。角鋼及鋼管接地體應垂直配置。除接地體外，接地體引出線的垂直部分和接地裝置焊接部位應防腐處理;在作防腐處理前，表面必須除銹并去掉焊接處殘留的焊藥。 (2)垂直接地體的間距不應小于其長度的3~5倍。水平接地體的間距應符合設計規(guī)定。當無設計規(guī)定時不宜小于5m。 (3)除環(huán)形接地體外，接地體埋設位置應在距建筑物3m以外。距建筑物出入口或人行道也應大于3m，如小于3m時，應采用均壓帶做法或在接地裝置上面敷設50~90mm厚度的瀝青層，其寬度應超過接地裝置2m。 (4)利用底板鋼筋或深基礎做接地體：按設計圖尺寸位置要求，標好位置，將底板鋼盤搭接焊好，再將柱主筋(不少于2根)底部與底板筋搭接焊，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標記，以便引出和檢查。 (5)利用柱形樁基及平臺鋼筋做接地體：按設計圖尺寸位置，找好樁基組數位置，把每組樁基四角鋼盤搭接封焊，再與柱主筋(不少于2根)焊好，并在室外地面以下將主筋焊接連接板，清理藥皮，并將兩根主筋用色漆做好標記，以便引出和檢查。</span> </p><h2> 防雷接地的重要性 </h2> <p> <span style="font-size:16px;">防雷接地在我們的生活中是至關重要的，它直接關系到建筑物和我們的人身安全，湖北防雷公司在防雷接地上給予了很大的支持，很好的解決了防雷的問題。雷擊時會產生強大的電流，產生的能量能夠對建筑物造成嚴重的破壞，甚至威脅到人類的生命，所以施工人員在防雷接地施工的時候一定要非常謹慎，不能出現任何紕漏差錯，其施工質量直接應影響到建筑物的安全和使用壽命，所以選擇一個好的施工監(jiān)理是非常重要的。湖北乾元上風電氣工程有限公司堅持“安全為先、服務為先、信譽為先”的經營宗旨，并以“質量至上、注重實效”的原則貫穿于各項工程的設計和施工。我們以質量的技術力量和良好的服務態(tài)度為您的防雷工程提供多方面的解決方案和技術支持，做到科學設計、科學施工，多方面、安全、合理、經濟的做好各類防雷建筑物的雷電防御及設備和人身的安全防護工作。以更好的工程質量和服務態(tài)度回報社會及廣大客戶的信任與厚愛。</span>

style="font-size:16px;">1、將支座鋼板固定在預埋的地腳螺栓上,焊上一塊肋板,再將避雷針立起,找直、找正后,進行點焊,然后加以校正,焊上其他三塊脅板。將引下線焊接在底板上,清理藥皮刷防銹漆。 2、避雷針應垂直安裝牢固。垂直度允許偏差為3/1000。 3、針體彎曲，安裝的垂直度超出允許偏差。應將針體重新調直，符合要求后再安裝。 4、**避雷針及其接地裝置與道路或建筑物的出入口保護距離不符合規(guī)定。其距離應大于3m，當小于3m時，應采取均壓措施或鋪設卵石或瀝青地。 5、選購時應注意：**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，其厚度應為4mm等。 6、注意：避雷針如果沒接地將是個迎雷針，所以必須謹慎。</span>
