<span style="font-size:16px;"> 武漢防雷公司通過(guò)合理的安裝防雷器，實(shí)現(xiàn)防雷工程的防雷效果，防雷器在我們的日常生活當(dāng)中應(yīng)用的也越普遍，防雷器又稱避雷器、浪涌保護(hù)器、電涌保護(hù)器、過(guò)電壓保護(hù)器等，主要包括電源防雷器和信號(hào)防雷器，防雷器是通過(guò)現(xiàn)代電學(xué)以及其它技術(shù)來(lái)防止被雷擊中的設(shè)備的損壞。</span>

1、耐沖擊次數(shù)，決定防雷器的使用壽命，氣體放電管放置一段時(shí)間后性能是不會(huì)下降的，除非漏氣了。要想檢測(cè)它的好壞，可以用可調(diào)高壓直流電源測(cè)試，或防雷器件測(cè)試儀。</span> </p> <p> <span style="font-size:16px;"> 2、反應(yīng)時(shí)間，決定防雷器能否及時(shí)反應(yīng)，快速泄放，潛江防雷檢測(cè)單位，潛江防雷檢測(cè)單位。</span> </p> <p> <span style="font-size:16px;"> 3，潛江防雷檢測(cè)單位、插入損耗，是指防雷器對(duì)線路的影響，基本上是從這三個(gè)指標(biāo)來(lái)判斷好壞，避雷器與被保護(hù)的電氣設(shè)備是相并聯(lián)的關(guān)系，如果避雷器靠電氣設(shè)備非常近(設(shè)電氣距離l=0)，則雷擊時(shí)電氣設(shè)備上的電壓就等于避雷器的殘壓，即有U設(shè)備 = U殘·避，殘壓越低U設(shè)備帶電越低，越安全。</span> 服務(wù)好防雷公司，乾元上風(fēng)防雷。潛江防雷檢測(cè)單位</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="潛江防雷檢測(cè)單位,防雷"

style="font-size:16px;">防雷器內(nèi)部受潮是一種比較常見(jiàn)的故障現(xiàn)象。具體表現(xiàn)是絕緣電阻低于2500MΩ，工頻放電電壓下降。 1)防雷器頂部緊固螺母松動(dòng)導(dǎo)致漏水;瓷套頂部密封用螺栓的墊圈沒(méi)有焊死，密封墊圈長(zhǎng)時(shí)間使用后會(huì)發(fā)生老化，潮氣、水分沿螺釘縫滲入內(nèi)腔也就不足為奇了。 2)底部密封試驗(yàn)的小孔沒(méi)有焊牢或者是沒(méi)有防雷器內(nèi)部受潮故障的原因及表現(xiàn)堵死導(dǎo)致水分或者是水蒸氣趁虛而入。 3)瓷套破裂、有、砂眼、裙邊膠合處有裂縫等等許多因素都會(huì)導(dǎo)致潮氣及水分進(jìn)入。 4)橡膠墊圈長(zhǎng)時(shí)間使用老化開(kāi)裂，失去密封作用。 5)底部壓緊用的扇形鐵片留有縫隙，沒(méi)有塞緊，底部密封橡膠墊圈位置不正，造成空隙滲入潮氣。 6)瓷套與法蘭膠合處不平整或瓷套有裂紋。</span> </p><h2> 機(jī)房防雷接地材料如何選擇 </h2> <p> <span style="font-size:16px;">（1）、導(dǎo)電率。以銅的導(dǎo)電率為****，銅包鋼接地極的導(dǎo)電率為30%。而角鋼的導(dǎo)電率只有8.6%。銅包鋼接地極是角鋼導(dǎo)電率的3.4倍。（2）、熱穩(wěn)定性。銅的熔點(diǎn)為1083度，短路時(shí)首要高溫度為450度，銅包鋼熔點(diǎn)為1510度，短路時(shí)為允許首要高溫度是450度，而角鋼的熔點(diǎn)為1510度，短路時(shí)首要高溫度為400度。在等面積情況下，銅材熱穩(wěn)定好，同等熱穩(wěn)定性時(shí)，角鋼所需的截面積為銅材的3倍，是銅包鋼接地極的2倍。（3）、耐腐蝕性。接地材料主要腐蝕有兩種其一為化學(xué)腐蝕，其二為電化學(xué)腐蝕，在多數(shù)情況下，這兩種腐蝕都是同時(shí)存在的。銅在土壤里的腐蝕速度大約是角鋼的1/10-1/50，而且電氣性能穩(wěn)定。銅的表面會(huì)產(chǎn)生附著性極強(qiáng)的氧化物銅綠，能夠?qū)?nèi)部銅起到很好的保護(hù)作用。阻斷腐蝕。當(dāng)銅與其他金屬主要是管道等同時(shí)存在與土壤里，銅作為陰極不會(huì)被腐蝕，而鋼材作為陽(yáng)極而會(huì)逐漸的被腐蝕。

1.發(fā)生強(qiáng)對(duì)流天氣時(shí)，如果在室外，應(yīng)立即尋找蔽護(hù)所。如裝有避雷針的、鋼架的或鋼盤混凝土建筑物，作為避雷場(chǎng)所，具有完整金屬車廂的車輛也可以利用；如找不到合適的避雷場(chǎng)所時(shí)，應(yīng)采用盡量降低重心和減少人體與地面的接觸面積，可蹲下，雙腳并攏，手放膝上，身向前屈，千萬(wàn)不要躺在地上、壕溝或土坑里，如披上雨衣，防雷效果更好。 2.切記，如果在野外，千萬(wàn)不要靠近空曠地帶或山頂上的孤樹，這里易受到雷擊；不要呆在開(kāi)闊的水域和小船上；高樹林子的邊緣，電線、旗桿的周圍和干草堆、帳篷等無(wú)避雷設(shè)備的高大物體附近，鐵軌、長(zhǎng)金屬欄桿和其它龐大的金屬物體近旁，山頂、制高點(diǎn)等場(chǎng)所也不能停留。另外，在野外的人群，無(wú)論是運(yùn)動(dòng)的，還是靜止的，都應(yīng)拉開(kāi)幾米的距離，不要擠在一起，也可躲在較大的山洞里。 3.雷電期間，好不要騎馬、騎自行車和摩托車；不要協(xié)帶金屬物體在露天行走；不要靠近避雷設(shè)備的任何部分；不要機(jī)。 4.注意當(dāng)您頭發(fā)豎起或皮膚發(fā)生顫動(dòng)時(shí)，可能要發(fā)生雷擊了，要立即倒在地上。受到雷擊的人可能被燒傷或嚴(yán)重休克，但身上并不帶電，可以安全地加以處理。</span>
