style="font-size:16px;">把建筑物中的金屬結(jié)構(gòu)沿鋼筋連成一整體，構(gòu)成一個(gè)大型金屬網(wǎng)籠。這種籠式避雷網(wǎng)既起屏蔽作用，又充當(dāng)引下線，是一種更加經(jīng)濟(jì)、美觀的安全的防雷方式。你到大街上轉(zhuǎn)一轉(zhuǎn)，可看到很多新樓的屋頂上不再有高聳的金屬桿和引下線了，那就是因?yàn)樗鼈円延蒙匣\式避雷網(wǎng)了。屋頂?shù)母鞣N金屬物都用導(dǎo)體連到籠式避雷網(wǎng)上。在屋頂四周還應(yīng)布設(shè)一條金屬帶，稱避雷帶，把它與避雷網(wǎng)接上。安裝了避雷裝置的建筑物是否就萬無一失不遭雷擊了呢？那不一定。有些高大建筑物雖安裝了避雷裝置，但因接地線斷裂等原因而"有形無用"了。可見要確保避雷裝置發(fā)揮效能，不但要正確設(shè)計(jì)、正確安裝，還要經(jīng)常保養(yǎng)，使它經(jīng)常處于良好狀態(tài)，這樣一般就可免受雷害了。眾達(dá)小編在這里提醒大家：一定要重視科學(xué)，不要輕視避雷技術(shù)各種環(huán)節(jié)的科學(xué)原理。更不可自以為是地自行安裝避雷針，那是危險(xiǎn)的，弄不好，反而會(huì)"引雷入室"，反倒遭了雷擊災(zāi)禍，這種事例不少。</span> </p><h2> 避雷針的作用是什么 </h2> <p> <span style="font-size:16px;">避雷針，又名防雷針、接閃桿，是用來保護(hù)建筑物、高大樹木等避免雷擊的裝置。避雷針由接閃器、接地引下線和接地體 3部分組成。接閃器通常采用直徑為 15～20mm、長度為1～2m的圓鋼或鋼管，固定于支柱上端經(jīng)接地引下線與接地體連接。當(dāng)雷云對地放電通道發(fā)展到臨近地面時(shí)，由于避雷針前列突出地面并有良好接地，在針尖附近的電場強(qiáng)度提高，聚積相反極性的電荷，引導(dǎo)放電。進(jìn)而防止建筑物或儀器蓄積過多電荷而遭受雷擊。一般來講，雷電并不會(huì)直接擊中避雷針，而避雷針本身如果被閃電擊中也有著融化及的危險(xiǎn)。避雷針具有一定的保護(hù)作用.</span>

src="https://tyunfile.71360.com/UploadFile/hbqysf/637232513372587891/689265.jpg"></div><h2> 避雷針有什么用途 </h2> <p> <span style="font-size:16px;">避雷，實(shí)際上是引雷德作用原理：在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，迅雷針和高樓頂知部都被感應(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道層形成了一個(gè)電容器，由于它較尖，即這個(gè)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)，避雷針與云層之版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．避雷針就可以權(quán)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。</span>
