style="font-size:16px;"> </span><span style="font-size:16px;">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(gè)電容器，由于它較尖，即這個(gè)電容器的兩極板正對(duì)面積很小，荊州通信避雷針廠家，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，荊州通信避雷針廠家。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(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</span>

style="font-size:16px;">2、避自雷器——間接接地。</span> </p> <p> <span style="font-size:16px;"> 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。</span> </p> <p> <span style="font-size:16px;"> 避雷器工作原理：</span> </p> <p> <span style="font-size:16px;"> 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，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>

</h1> <p> <span style="font-size:16px;">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)。</span> </p> <p> <span style="font-size:16px;">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(chǎng)強(qiáng)度增加到極限值的雷電云電場(chǎng)發(fā)生畸變，開始電離并下行先導(dǎo)屬放電；避雷針在強(qiáng)電場(chǎng)作用下產(chǎn)生前列放電，形成向上先導(dǎo)放電。</span> </p> <p> <span style="font-size:16px;">兩者會(huì)合形成雷電通路，隨之瀉入大地，達(dá)到避雷效果。實(shí)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(duì)象直接遭雷擊。</span> </p> <p> <span
