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> </p><h2> 汽車安裝避雷針嗎 </h2> <p> <span style="font-size:16px;">汽車不安裝避雷針，但車殼是金屬的，因屏蔽作用，就算閃電擊中汽車，也不會傷人，因此，車廂是躲避雷擊的理想地方。汽車的輪胎絕緣性能相當好，雷電擊到汽車帶電，但電流傳不到地下形不成回路，不會對人和汽車造成危害。汽車的輪胎外帶有水或其它導電性物質(zhì)，有的帶有防靜電接地線。雷電擊到汽車帶電，電流有從金屬表面流動的特性，不會對人產(chǎn)生危害。電流就通過汽車表面?zhèn)鞯綆в兴蚱渌鼘щ娦晕镔|(zhì)的輪胎，帶有防靜電接地線傳到地下形成回路，不會對人和汽車造成危害。</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?！罢劬€法”的主要特點是設計直觀，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計和施工。我們以質(zhì)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(jīng)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(zhì)量和服務態(tài)度回報社會及廣大客戶的信任與厚愛</span>。避雷針廠家，湖北乾元上風電氣供應，品質(zhì)優(yōu)良值得推薦！隨州建筑避雷針生產(chǎn)廠家</p><p
