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)。以避雷針作為接閃器的防雷電原理是：避雷針通過(guò)導(dǎo)線接入地下，與地面形成等電位差，利用自身的高度，宜昌通信避雷針檢測(cè)，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(kāi)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。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，宜昌通信避雷針檢測(cè)，避雷針是引雷針，可將周圍的雷電引來(lái)并提前放電，將雷電電流通過(guò)自身的接地導(dǎo)體傳向地面，宜昌通信避雷針檢測(cè)，避免保護(hù)對(duì)象直接遭雷擊。參考資料來(lái)源：百度百科——避雷針</span>

</p><h2> 城市有避雷針 </h2> <p> <span style="font-size:16px;">家中是否也要安裝避雷針據(jù)調(diào)查，雷擊對(duì)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(lái)越普遍，甚至還會(huì)造成人員傷亡，嚴(yán)重威脅到人們的財(cái)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(huì)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(wèn)題，事實(shí)上并非如此!

style="font-size:16px;">1、避雷針，又名防雷針、接閃桿，是用來(lái)保護(hù)建筑物、高大樹(shù)木等避免雷擊的裝置。在被保護(hù)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(lái)。避雷針規(guī)格必須符合GB標(biāo)準(zhǔn)，每一個(gè)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(shí)它使地面電場(chǎng)發(fā)生畸變。在避雷針的頂端，形成局部電場(chǎng)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?lè)烹?，再通過(guò)接地引下線和接地裝置將雷電流引入大地，從而使被保護(hù)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(gè)隔離的導(dǎo)電系統(tǒng)。 4、當(dāng)云中有電荷時(shí)，這隔出的部分上部感應(yīng)出與云中電異號(hào)的電荷，而下部感應(yīng)出與云中電同號(hào)的電荷，如果上部和云中電起放電作用時(shí)，強(qiáng)大的放電電流只能通過(guò)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(lái)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(hù)一定的建筑面積。對(duì)于較大的建筑物也需要豎起幾條避雷針。</span>

style="font-size:16px;">據(jù)中國(guó)的規(guī)范規(guī)定，單支避雷針的保護(hù)范圍是一個(gè)錐體，高度為h的避雷針，其在地面上的保護(hù)半徑r=1.5h；在被保護(hù)物高度hx的水平面上，其保護(hù)半徑rx為：rx=(1.5h-2hx)P。 “折線法”是比較成熟的方法，在電力系統(tǒng)又稱“規(guī)程法”，即單支避雷針的保護(hù)范圍是一個(gè)以避雷針為軸的折線圓錐體。單支避雷針的保護(hù)范圍在DL/T620-997《交流電氣裝置的過(guò)電壓保護(hù)和絕緣配合》標(biāo)準(zhǔn)中有所規(guī)定；“滾球法”是國(guó)際電工會(huì)（IEC）推薦的接閃器保護(hù)范圍計(jì)算方法之一。我國(guó)建筑防雷規(guī)范GB50057-1994Z中也把“滾球法”強(qiáng)制作為計(jì)算避雷針保護(hù)范圍的方法。滾球法是以hR為半徑的一個(gè)球體沿需要防止擊雷的部位滾動(dòng)，當(dāng)球體只觸及接閃器（包括被用作接閃器的金屬物）或只觸及接閃器和地面（包括與大地接觸并能承受雷擊的金屬物），而不觸及需要保護(hù)的部位時(shí)，則該部分就得到接閃器的保護(hù)。</span>
