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，荊州橋梁避雷針制作、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，荊州橋梁避雷針制作，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，荊州橋梁避雷針制作。</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232452426259766/8150720.jpg"></div><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 , 進行點焊 , 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，應彎曲成弧形再與避雷帶（網(wǎng)）并齊進行搭接焊接。不同平面的避雷帶（網(wǎng)）應至少有兩處互相連接，連接應采用焊接。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。避雷針安裝時應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)充當引下線的鋼筋進行連接（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>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372812500/1888634.jpg"></div><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> </p><h2> 裝置避雷針是避免雷擊的有效方法。 </h2> <p> <span style="font-size:16px;">在房屋處豎一金屬棒，棒下端連一條足夠粗的銅線，銅線下端連一塊金屬板埋入地下深處潮濕處。金屬棒的上端須是一個尖頭或分叉為幾個尖頭。有了這樣的裝置，當空中有帶電的云時。避雷針的前列因靜電感應就集中了異種電荷，發(fā)生前列放電，與云內(nèi)的電相中和，避免發(fā)生激烈的雷電、這就是避雷針能避雷的一方面。但這種作用頗慢，如果云中積電很快，或一塊帶有大量電荷的云突然飛來，有時來不及按上述方式中和，于是有強烈的放電，加雷電仍會發(fā)生。但這時由于避雷針高過周圍物體，它的前列又集中了與云中電異號的電荷，如果雷電是在云和地面物之間發(fā)生，放電電流主要通過避雷針流入大地，因此，不會打在房屋或附近人的身上，只會打在避雷針上了。由此可見，避雷針的前列放電作用會減少地面物與云之間打雷的可能性；到了不可避免時，它自己就負擔了雷的打擊，房屋與人得到了安全。由于避雷針的構(gòu)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)。</span>
