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(dāng)空中有帶電的云時。避雷針的前列因靜電感應(yīng)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(dān)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(dǎo)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(dǎo)電系統(tǒng)。</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(yīng)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(yīng)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(yīng)為4mm。</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(shè)備并聯(lián)，正常時泄漏電流很小，不影響系統(tǒng)運行。當(dāng)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(shè)備的絕緣不被擊穿。</span>

style="font-size:16px;">1、避雷針，又名防雷針、接閃桿，是用來保護建筑物、高大樹木等避免雷擊的裝置。在被保護物頂端安裝一根接閃器，用符合規(guī)格導(dǎo)線與埋在地下的泄流地網(wǎng)連接起來。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個防雷類別需要的避雷針高度規(guī)格都不一樣。 2、當(dāng)雷云放電接近地面時它使地面電場發(fā)生畸變。在避雷針的頂端，形成局部電場集中的空間，以影響雷電先導(dǎo)放電的發(fā)展方向，引導(dǎo)雷電向避雷針放電，再通過接地引下線和接地裝置將雷電流引入大地，從而使被保護物體免遭雷擊。 3、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(dǎo)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(dǎo)電系統(tǒng)。 4、當(dāng)云中有電荷時，這隔出的部分上部感應(yīng)出與云中電異號的電荷，而下部感應(yīng)出與云中電同號的電荷，如果上部和云中電起放電作用時，強大的放電電流只能通過建筑物放出大量熱量，于是引起雷擊。這樣不但不能避雷，反而還招來雷禍。為防意外，高大建筑物豎起幾條避雷針。另外，每一又避雷針只能保護一定的建筑面積。對于較大的建筑物也需要豎起幾條避雷針。</span>

style="font-size:16px;">避雷針由接閃器、接地copy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。在雷雨天氣，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百的電荷。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)云層上度電荷較多時，避雷針與云層之間的空氣就很容易被擊穿，成問為導(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。帶電的云，首先是從上往下運行,在高處安避雷針，就首先將云中的電放答掉,以后到房子接觸云的時候，就基本沒有或只有少部分電而沒有危險了</span>
