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(yīng)上大量電荷，由于避雷針針頭是尖的，所以靜電感應(yīng)時，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，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，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(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>

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，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持“安全為先、服務(wù)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(shè)計和施工。</span> </p><h2> 避雷針的作用是什么？ </h2> <p> <span style="font-size:16px;">常規(guī)防雷電可分為防直擊雷電、防感應(yīng)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(dǎo)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(dǎo)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(dǎo)放電；兩者會合形成雷電通路，隨之瀉入大地，達(dá)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(dǎo)體傳向地面，避免保護(hù)對象直接遭雷擊。</span>

style="font-size:16px;">據(jù)中國的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。 “折線法”是比較成熟的方法，在電力系統(tǒng)又稱“規(guī)程法”，即單支避雷針的保護(hù)范圍是一個以避雷針為軸的折線圓錐體。單支避雷針的保護(hù)范圍在DL/T620-997《交流電氣裝置的過電壓保護(hù)和絕緣配合》標(biāo)準(zhǔn)中有所規(guī)定；“滾球法”是國際電工會（IEC）推薦的接閃器保護(hù)范圍計算方法之一。我國建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強制作為計算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個球體沿需要防止擊雷的部位滾動，當(dāng)球體只觸及接閃器（包括被用作接閃器的金屬物）或只觸及接閃器和地面（包括與大地接觸并能承受雷擊的金屬物），而不觸及需要保護(hù)的部位時，則該部分就得到接閃器的保護(hù)。</span>
