style="font-size:16px;">1、避雷針——直接接地，十堰工廠避雷針安裝公司。利用電荷前列放電現(xiàn)象不讓雷擊發(fā)生。避雷針和被保護(hù)物體是分開的，可以保護(hù)比較集中的重要物體。 2、避自雷器——間接接地。利用過電壓放電現(xiàn)象讓雷擊電壓通過避雷器進(jìn)入大地。避雷器和被保護(hù)物體是連接的，可以保護(hù)帶電物體，如輸電線路。避雷器工作原理：避雷器實(shí)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，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(hù)設(shè)備并聯(lián)，正常時(shí)泄漏電流很小，不影響系統(tǒng)運(yùn)行。當(dāng)系統(tǒng)有過電壓時(shí)（即超過正常運(yùn)行電壓的高電壓），避雷器即呈現(xiàn)低電阻泄放答能量，十堰工廠避雷針安裝公司，同時(shí)限制系統(tǒng)電壓的幅值，確保電氣設(shè)備的絕緣不被擊穿。</span>

2、采用鍍鋅鋼管管制作針尖知，管壁厚度不得小于3mm,針尖刷錫長度不得小于70mm 3、避雷針應(yīng)垂直安裝牢固。垂直度允許偏差為3/1000。 4、焊接要求焊接應(yīng)采用搭接焊，其搭接長度必須符合下列規(guī)定： 5、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 6、圓鋼為其直徑的6倍。 7、圓鋼與扁鋼連接時(shí)，其長度為圓鋼直徑的6倍。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。</span> 十堰工廠避雷針安裝公司防雷避雷針安裝，湖北乾元上風(fēng)電氣供應(yīng)，品質(zhì)有保證！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="十堰工廠避雷針安裝公司,避雷針"

style="font-size:16px;">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。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(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。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(dǎo)入大地，使其不對高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。按我國統(tǒng)計(jì)的雷電流幅值約為300 kA，其對應(yīng)的雷擊高度為408 m。取雷擊定位高度為400m，可得出不同高度避雷針的保護(hù)區(qū)和散擊區(qū)的地表半徑見表1。我國舊式民房一般高度在10 m以下，避雷帶和避雷網(wǎng)的高度與房高相同，安裝的短針防雷其高度為1～2 m，它們引起的散擊現(xiàn)象不明顯；高聳建筑物和高架避雷針引雷招致雷擊率增高和存在散擊區(qū)。</span> </p><h2> 避雷針安裝的正確方法 </h2> <p> <span style="display:none;"></span><span style="font-size:16px;">一、避雷針的安裝避雷針（接閃器）的安裝主要包括避雷針的安裝和避雷帶（網(wǎng)）的安裝。（一）避雷針的安裝安裝注意事項(xiàng)如下：（1）建筑物上的避雷針和建筑物頂部的其他金屬物體應(yīng)連接成一個整體。（2）不得在避雷針構(gòu)架上架設(shè)低壓線路或通訊線路。（二）避雷帶和避雷網(wǎng)的安裝 1.明裝避雷帶（網(wǎng)）安裝適于安裝在建筑物的屋脊、屋檐（坡屋頂）或屋頂邊緣及女兒墻（平屋頂）等處。（1）避雷帶在屋面混凝土支座上的安裝避雷帶（網(wǎng)）的支座可以在建筑物屋面面層施工過程中現(xiàn)場澆制，也可以預(yù)制再砌牢或與屋面防水層進(jìn)行固定。 ( 2)避雷帶在墻或天溝支架上的安裝沿墻安裝時(shí)，應(yīng)使用支架固定；并應(yīng)盡量隨結(jié)構(gòu)施工預(yù)埋支架。支架的支起高度不應(yīng)小于150mm 。直線段支架水平間距為1-1. 5m，垂直間距為1.

在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，迅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，而靜電感應(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。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(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。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(dǎo)人大地，使其不對高層建筑構(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、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)社會及廣大客戶的信任與厚愛。防雷避雷針廠家，湖北乾元上風(fēng)電氣供應(yīng)，歡迎您來點(diǎn)電咨詢！荊州變電站避雷針生產(chǎn)廠家</p><p style="text-indent:25px">避雷針安裝價(jià)格，湖北乾元上風(fēng)電氣供應(yīng)。十堰工廠避雷針安裝公司</p><h2> 關(guān)于避雷針安裝的方法 </h2> <p> <span style="font-size:16px;"> 避雷針安裝要先將支座鋼板固定在預(yù)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(jìn)行點(diǎn)焊 , 然后加以校正 , 焊上其他三塊脅板。后面將引下線焊接在底板上 , 清理藥皮刷防銹漆。支座和支架，水平間距為1-1. 5m，轉(zhuǎn)彎處為0. 25m-0. 5m。引下線的上端與避雷帶（網(wǎng)）的交接處，應(yīng)彎曲成弧形再與避雷帶（網(wǎng)）并齊進(jìn)行搭接焊接。不同平面的避雷帶（網(wǎng)）應(yīng)至少有兩處互相連接，連接應(yīng)采用焊接。建筑物屋頂上的突出金屬物體，如旗桿、透氣管、鐵欄桿、爬梯、冷卻水塔、電視天線桿等，這些部位的金屬導(dǎo)體都必須與避雷帶（網(wǎng)）焊接成一體。避雷帶通過伸縮沉降縫的做法：應(yīng)將避雷帶向側(cè)面彎成半徑為100mm的弧形，且支持卡子中心距建筑物邊緣距離減至400mm，可以將避雷帶向下部彎曲。避雷針安裝時(shí)應(yīng)在建筑物首層起每三層設(shè)均壓環(huán)一圈。可將結(jié)構(gòu)圈梁鋼筋與柱內(nèi)充當(dāng)引下線的鋼筋進(jìn)行連接（綁扎或焊接）作為均壓環(huán)。沒有組合柱和圈梁的建筑物，應(yīng)每三層在建筑物外墻內(nèi)敷設(shè)一圈12mm鍍鋅圓鋼作為均壓環(huán)，并與防雷裝置的所有引下線連接。</span>
