有些客戶會有疑問，電源防雷器能用多久？是不是只能防一次雷擊就壞了呢？今天科比特小編就帶你了解一下電源防雷器的使用壽命。
GB 18802.11標(biao)準中規定：電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)防(fang)雷(lei)器是用(yong)于限制瞬態過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和泄(xie)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的電(dian)(dian)(dian)(dian)(dian)(dian)器。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)防(fang)雷(lei)器是并(bing)聯在主回(hui)路(lu)上，其作用(yong)是限制瞬態過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和泄(xie)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，平時是高阻態狀態，當電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中出現TOV時則(ze)會導通并(bing)泄(xie)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，可視為直接(jie)接(jie)地的導線，能將(jiang)主回(hui)路(lu)中的電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)泄(xie)放(fang)至接(jie)地線。電(dian)(dian)(dian)(dian)(dian)(dian)涌(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)泄(xie)放(fang)完(wan)之后(hou)，又恢復成高阻態狀態，繼續保護著(zhu)設備。
那么電(dian)源(yuan)防雷(lei)器(qi)能(neng)承受多少次雷(lei)擊呢？科比特(te)電(dian)源(yuan)防雷(lei)器(qi)的(de)(de)設計壽命是20年(nian)，但是當他(ta)們(men)被(bei)安(an)裝在不同(tong)的(de)(de)項目(mu)中時，它們(men)的(de)(de)命運(yun)也(ye)就各不相同(tong)了。電(dian)源(yuan)防雷(lei)器(qi)能(neng)用多久(jiu)？
影響電(dian)源防雷器使用壽(shou)命(ming)(ming)的原(yuan)因有(you)很多，其(qi)中主要(yao)(yao)原(yuan)因要(yao)(yao)取決于當地的電(dian)力系統是(shi)否穩(wen)定(ding)，是(shi)否在(zai)(zai)雷暴高(gao)發區(qu)，當電(dian)力環境(jing)穩(wen)定(ding)，且不在(zai)(zai)雷電(dian)高(gao)發區(qu)時，電(dian)源防雷器可(ke)以在(zai)(zai)它的整個(ge)生命(ming)(ming)周期內安然無恙。
在國(guo)內，電(dian)源(yuan)防雷(lei)器(qi)經常出現(xian)問題的(de)行業(ye)(ye)主要是通(tong)信、風(feng)電(dian)、鐵路等行業(ye)(ye)領域，因為多(duo)諧波和(he)惡劣(lie)的(de)使用(yong)環境，造成(cheng)了這些(xie)(xie)行業(ye)(ye)的(de)電(dian)涌(yong)(yong)保護(hu)器(qi)頻繁(fan)動作(zuo)，電(dian)源(yuan)防雷(lei)器(qi)劣(lie)化速度快，有時甚至發(fa)生(sheng)起火(huo)現(xian)象。所以(yi)這些(xie)(xie)行業(ye)(ye)的(de)電(dian)源(yuan)防雷(lei)器(qi)需要用(yong)高(gao)質量(liang)的(de)浪涌(yong)(yong)保護(hu)器(qi)，不容易起火(huo)。在(zai)正(zheng)常的(de)環境中，電(dian)源(yuan)防雷(lei)器(qi)還(huan)是很耐用(yong)的(de)，有時10多(duo)年都不壞。
實際上在電源防(fang)雷(lei)器(qi)的(de)保(bao)護(hu)動(dong)作發生(sheng)過程中，我們是(shi)觀(guan)察不到(dao)的(de)。電源防(fang)雷(lei)器(qi)并不是(shi)使用一次(ci)就(jiu)會壞掉，通常(chang)其(qi)(qi)發生(sheng)一次(ci)沖(chong)擊后(hou)，能(neng)(neng)迅(xun)速的(de)從(cong)低阻恢復到(dao)高(gao)阻狀態，正常(chang)都能(neng)(neng)自動(dong)復位(wei)，直到(dao)其(qi)(qi)壽命(ming)終(zhong)結時，表(biao)面的(de)指(zhi)示窗口會從(cong)綠色變成紅色，就(jiu)表(biao)示其(qi)(qi)防(fang)雷(lei)失(shi)效了，需要更換防(fang)雷(lei)器(qi)。
