1、在選擇**避雷針的裝設地點時，應使避雷針及其接地裝置與配電裝置之間抄保持以下規(guī)定的距離：在地面上，由**避雷針到配電裝置的導電部分以及到變電所電氣設備和構架地部分間的空間距離不應小于6m,在地下，由**避襲雷針本身的接地裝置與變電所接地網(wǎng)間近的地中距離一般不小于3m。 2、**避雷針的接地電阻一般不宜超過10Ω。 3，十堰信號避雷針廠家哪家好、為了防止雷擊避雷針時，雷電波由電線傳入室內(nèi)，危及人身安全，所以不得在避雷針構架上架設電壓線路或通信線路。裝有避雷針的構架上的照明燈電源線，必須采用直埋于地下的帶金屬保護層的電纜或穿入金屬管的導線，十堰信號避雷針廠家哪家好。電纜保護層或金屬管必百須接地，埋地長度在10m以上，方可與配電裝置的接地網(wǎng)連接，貨與電源線度、低壓配電裝置相連接，十堰信號避雷針廠家哪家好。</span>

style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應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。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體傳向地面，避免保護對象直接遭雷擊。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513374218750/1846083.jpg"></div><h2> 避雷針的構造 </h2> <p> <span style="font-size:16px;">避雷針由接閃器、接地copy引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。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上大量電荷，由于避雷針針頭是尖的，所以靜電感應時，導體前列總是聚集了多百的電荷。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，當云層上度電荷較多時，避雷針與云層之間的空氣就很容易被擊穿，成問為導體。這樣，帶電云層與避雷針形成通路，而避雷針又是接地的，避雷針就可以把云層上的電荷導入大地，使其不對高層建筑構成危險，保證了它的安全。帶電的云，首先是從上往下運行,在高處安避雷針，就首先將云中的電放答掉,以后到房子接觸云的時候，就基本沒有或只有少部分電而沒有危險了</span> </p><h2> 樹名木防雷包括： </h2> <p> <span style="font-size:16px;">避雷針，引下線，雷電計數(shù)器，防雷接地系統(tǒng)施工！ 1）避雷針要采用捷力通防側閃電的玻璃鋼材質，高度根據(jù)樹冠和樹高滾球半徑法計算，可以加裝一支玻璃鋼避雷針，兩支避雷針到多支玻璃鋼避雷針！避雷針固定要考慮長久性穩(wěn)定性！ 2）引下線敷設不能影響美觀，比如采用仿生樹皮，仿生樹根做隱蔽，固定時不能傷害到樹干，雷電計數(shù)器則是為了記錄雷擊環(huán)境，做重點雷電檢測防護。 3）防雷接地同樣也很重要：不能用有污染的接地材料，不能破壞樹根等，方案采用零歐復合接地材料，零歐復合接地體壽命可試用百年以上，不腐蝕無污染導電性能好，距離樹干三米外為宜，采用深井接地系統(tǒng)施工！特殊地方采用地埋式接地電阻測試儀器，雷電峰值記錄儀器等！采用科學的雷電防護措施保護每一顆古樹名木！</span> 避雷針安裝價格，湖北乾元上風電氣供應，品質有保證！</p><div

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(xiàn)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>

style="display:none;"></span><span 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。 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)。 4、當云中有電荷時，這隔出的部分上部感應出與云中電異號的電荷，而下部感應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。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> 十堰信號避雷針廠家哪家好</p><p
