style="font-size:16px;">安裝避雷針時(shí)，應(yīng)注意以下事項(xiàng)： 1、在選擇**避雷針的裝設(shè)地點(diǎn)時(shí)，應(yīng)使避雷針及其接地裝置與配電裝置之間抄保持以下規(guī)定的距離：在地面上，由**避雷針到配電裝置的導(dǎo)電部分以及到變電所電氣設(shè)備和構(gòu)架地部分間的空間距離不應(yīng)小于6m,在地下，由**避襲雷針本身的接地裝置與變電所接地網(wǎng)間近的地中距離一般不小于3m。 2、**避雷針的接地電阻一般不宜超過(guò)10Ω，荊州變電站避雷針安裝。 3、為了防止雷擊避雷針時(shí)，雷電波由電線(xiàn)傳入室內(nèi)，危及人身安全，所以不得在避雷針構(gòu)架上架設(shè)電壓線(xiàn)路或通信線(xiàn)路。裝有避雷針的構(gòu)架上的照明燈電源線(xiàn)，必須采用直埋于地下的帶金屬保護(hù)層的電纜或穿入金屬管的導(dǎo)線(xiàn)。電纜保護(hù)層或金屬管必百須接地，埋地長(zhǎng)度在10m以上，方可與配電裝置的接地網(wǎng)連接，貨與電源線(xiàn)度，荊州變電站避雷針安裝，荊州變電站避雷針安裝、低壓配電裝置相連接。</span>

style="font-size:16px;">在雷雨天氣，高樓上空出現(xiàn)帶電云層時(shí)，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(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，電容也就很小，也就是說(shuō)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。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(duì)高層建筑構(gòu)成危險(xiǎn)，保證了它的安全。</span> </p><h2> 避雷針的作用 </h2> <p> <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(xiàn)和接地裝置三部分組成。接閃器就是通常所說(shuō)的''避雷針''，它通過(guò)引下線(xiàn)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(chǎng)強(qiáng)度相對(duì)較大，空氣也容易被擊穿，雷電流通過(guò)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(guò)引下線(xiàn)至接地裝置而泄放大地，從而使保護(hù)對(duì)象免遭雷擊。避雷針的保護(hù)范圍可用滾球法來(lái)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(duì)于類(lèi)、第二類(lèi)和第三類(lèi)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(wú)實(shí)際效果。</span>

style="font-size:16px;">用什么原理才不會(huì)被雷擊中避雷針從原理百上講，不是避雷，而是引雷，是引雷針。正是因?yàn)樗缺槐Ｗo(hù)物高，雷電流通過(guò)較高的避雷針入地，釋放較高的雷電壓，才使比避雷針低的建筑物或設(shè)度備不會(huì)被雷擊中，從而保護(hù)設(shè)備或建筑物的安全。知一般來(lái)說(shuō)，避雷針越高，保護(hù)范圍就越大，保護(hù)效果也越好，但考慮到避雷針建設(shè)的安全性和經(jīng)濟(jì)性，避雷針大多建設(shè)在35米-45米之間。道用幾根避雷針，要看需要保護(hù)多大的范圍，如果需要保護(hù)的范圍較大，則專(zhuān)需要的避雷針數(shù)量就多，需要保護(hù)的范圍屬較小，則需要的避雷針數(shù)量就少，甚至1根就夠了。具體安裝數(shù)量，要通過(guò)計(jì)算及繪制避雷針保護(hù)范圍圖來(lái)確定。</span>
