D為滾球半徑（度閃擊距離）類(lèi)建筑物為D＝30米第二類(lèi)建筑物為D＝45米第三類(lèi)建筑物為D＝60米保護(hù)范圍采用規(guī)范之計(jì)算公式： Rx=?{h(2hr-h)}-?{hx(2hr-hx)} 其中Rx為避雷針在距離地問(wèn)面hx米處的保護(hù)半徑（米）； hr為滾球半徑,根據(jù)建筑物類(lèi)別取值30、45、60； hx為被保護(hù)物的高度一般來(lái)說(shuō)，避雷針越高，恩施小區(qū)避雷針安裝，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)答性，避雷針大多建設(shè)在35米-45米之間，恩施小區(qū)避雷針安裝。</span>

style="font-size:16px;">所謂雷電現(xiàn)象，就是空中云層積累的電荷達(dá)到頗大數(shù)量時(shí)，它與附近的帶電云層或物體間產(chǎn)生很大的電勢(shì)差，形成很強(qiáng)的電場(chǎng)，兩部分異性電荷突破周?chē)諝獾淖璧K去中和，發(fā)生強(qiáng)烈放電，這時(shí)在電通過(guò)的路徑上發(fā)出聲和光，就是雷電。雷電通常發(fā)生在不同的云塊之間，或云的下部與地面物之間。我們要避免的只是云和地或地上物之間的雷電。如果這塊云的上部帶正電，下部帶負(fù)電，則地面上感應(yīng)出來(lái)的電是正電，此時(shí)地面上的凸出物（房屋、樹(shù)或人體）就有可能與云中電荷發(fā)生放電現(xiàn)象，遭到雷擊的災(zāi)禍</span> </p><h2> 避雷針的構(gòu)造 </h2> <p> <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(zhǎng)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(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(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)云層上度電荷較多時(shí)，避雷針與云層之間的空氣就很容易被擊穿，成問(wèn)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。帶電的云，首先是從上往下運(yùn)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(shí)候，就基本沒(méi)有或只有少部分電而沒(méi)有危險(xiǎn)了</span>

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。 3、為了防止雷擊避雷針時(shí)，雷電波由電線傳入室內(nèi)，危及人身安全，所以不得在避雷針構(gòu)架上架設(shè)電壓線路或通信線路。裝有避雷針的構(gòu)架上的照明燈電源線，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。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，貨與電源線度、低壓配電裝置相連接。</span>
