style="font-size:16px;">家中是否也要安裝避雷針據(jù)調(diào)查，雷擊對電子電器設(shè)備的損壞始終高居雷電傷害榜*位，由雷電所引發(fā)的家用電器壽命降低、故障不斷、擊毀擊壞等情況越來越普遍，甚至還會造成人員傷亡，嚴(yán)重威脅到人們的財產(chǎn)和生命安全。因此，防止家電夏季被“雷”,其實(shí)遠(yuǎn)遠(yuǎn)比防暑更重要! 避雷針其實(shí)不“避雷” 通常情況下，城市建筑一般都會安裝避雷針，許多人以為有了避雷針，就可以不用再操心“防雷”問題，事實(shí)上并非如此! (遭遇雷擊后的電視機(jī)殘骸) 雷電有直擊雷和感應(yīng)雷之分。在家用電器的使用過程中，插座是一個防雷關(guān)口，要保護(hù)電器不被雷擊損害，就一定要使用具備防雷功能的專業(yè)插座。目前，市面上的一些防雷插座存在著較嚴(yán)重的質(zhì)量問題，如防雷技術(shù)不成熟;使用質(zhì)量低劣(三無產(chǎn)品:無廠家、無參數(shù)、無證書)的防雷元器件;未經(jīng)專業(yè)防雷檢測機(jī)構(gòu)的檢驗(yàn)……等等，不僅防雷性能無法得到保證，甚至還存在更大的安全。</span>

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，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。避雷針具有一定的保護(hù)作用.</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(qiáng)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(qiáng)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(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)對象直接遭雷擊。</span>

style="font-size:16px;">垂直接地體的間距不應(yīng)小于其長度的3～5倍。水平接地體的間距應(yīng)符合設(shè)計規(guī)定。當(dāng)無設(shè)計規(guī)定時不宜小于5m。除環(huán)形接地體外，接地體埋設(shè)位置應(yīng)在距建筑物3m以外。距建筑物出入口或人行道也應(yīng)大于3m，如小于3m時，應(yīng)采用均壓帶做法或在接地裝置上面敷設(shè)50～90mm厚度的瀝青層，其寬度應(yīng)超過接地裝置2m。 1、裝置避雷針是避免雷擊的有效方法。在房屋高處豎一金屬棒，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。 2、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(qiáng)烈的放電，加雷電仍會發(fā)生。</span>

style="font-size:16px;">再也不怕打雷了防直擊雷裝置由接閃器、引下線和接地裝置三部分組成。接閃器就是通常所說的''避雷針''，它通過引下線和接地裝置與大地相連。由于''前列放電''效應(yīng)，大地被感應(yīng)出的電荷易聚集在針尖處，使得雷云與避雷針附近空間的電場強(qiáng)度相對較大，空氣也容易被擊穿，雷電流通過避雷針提供的放電通道泄放入地。這樣，雷擊雖然還是發(fā)生了，但總是擊向避雷針，而不是擊向要保護(hù)的物體，所以避雷針實(shí)際是引雷針。它將雷電吸引至自身，使雷電流通過引下線至接地裝置而泄放大地，從而使保護(hù)對象免遭雷擊。避雷針的保護(hù)范圍可用滾球法來確定。在一定范圍內(nèi)，隨著避雷針的增高，其保護(hù)范圍也隨之?dāng)U大，達(dá)到一定高度以后，其保護(hù)范圍就不再擴(kuò)大了。避雷針的高度是這樣確定的：對于類、第二類和第三類防雷建筑物，避雷針的有效高度分別為30米、45米和60米，所以盲目增加避雷針高度，既浪費(fèi)又無實(shí)際效果。</span>
