style="font-size:16px;">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，荊州橋梁避雷針廠家哪家好，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，荊州橋梁避雷針廠家哪家好，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。按我國統(tǒng)計的雷電流幅值約為300 kA，其對應的雷擊高度為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，荊州橋梁避雷針廠家哪家好，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>

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連接成一個整體。（2）不得在避雷針構架上架設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，也可以預制再砌牢或與屋面防水層進行固定。 ( 2)避雷帶在墻或天溝支架上的安裝沿墻安裝時，應使用支架固定；并應盡量隨結構施工預埋支架。支架的支起高度不應小于150mm 。直線段支架水平間距為1-1. 5m，垂直間距為1. 5-2m，且支架間距應平均分布。避雷帶（網(wǎng)）在建筑物天溝上安裝使用支架固定時，應隨土建施工先設置好預埋件，支架與預埋件進行焊接固定。</span> 黃岡小區(qū)避雷針加工廠家避雷針廠家，湖北乾元上風電氣供應，品質(zhì)優(yōu)良值得推薦！</p><div style="width:100%;text-align:

style="font-size:16px;">直擊雷避雷針/特殊避雷針/提前預放電避雷針 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> 避雷器與避雷針區(qū)別： </h2> <p> <span style="font-size:16px;">1、避雷針——直接接地。利用電荷前列放電現(xiàn)象不讓雷擊發(fā)生。避雷針和被保護物體是分開的，可以保護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，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(lián)，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(xiàn)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>

1、所有金屬部件必須鍍鋅，操作時注意保護鍍鋅層。 2、采用鍍鋅鋼管管制作針尖，管壁厚度不得小于3mm,針尖刷錫長度不得小于70mm 3、避雷針應垂直安裝牢固。垂直度允許偏差為3/1000。 4、扁鋼為其寬度的2倍(且至少3個棱邊焊接)。 5、圓鋼為其直徑的6倍。 6、圓鋼與扁鋼連接時，其長度為圓鋼直徑的6倍。 7、避雷針一般采用圓鋼或鋼管制成，其直徑不應小于下列數(shù)值： **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。</span> 避雷針價格，湖北乾元上風電氣供應，歡迎您來點電咨詢！仙桃醫(yī)院避雷針廠家直銷</p><p
