恒流電源的老化(hua)如(ru)今(jin)也是一(yi)個非常(chang)值(zhi)得重視的問題，那么電源老化(hua)我(wo)們怎樣(yang)及時(shi)的發現和解決(jue)呢，今(jin)天我(wo)們就來看一(yi)下。

　　檢(jian)測(ce)老(lao)化了解哪些基本性(xing)能參數測(ce)試(shi)。檢(jian)測(ce)老(lao)化電(dian)(dian)(dian)(dian)壓范(fan)圍：在(zai)標準電(dian)(dian)(dian)(dian)壓范(fan)圍內電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)都能正(zheng)常(chang)工作(zuo)。輸出電(dian)(dian)(dian)(dian)壓要(yao)(yao)(yao)滿足檢(jian)驗電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)能帶LED的(de)(de)(de)數量(liang)，輸出電(dian)(dian)(dian)(dian)流(liu)(liu)要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)是電(dian)(dian)(dian)(dian)流(liu)(liu)恒定為(wei)350毫安左右(you)，恒流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)如果(guo)電(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)恒定就不(bu)能稱(cheng)為(wei)恒流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)了，所以(yi)這(zhe)是基礎的(de)(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)。電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)效(xiao)率：要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)不(bu)低于88%，要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)也是可以(yi)的(de)(de)(de)，不(bu)然就是老(lao)化了的(de)(de)(de)特點。功率因(yin)數：要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)功率因(yin)數大于0.95，由此可見(jian)，功率還是挺高的(de)(de)(de)。低溫測(ce)試(shi)：要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)在(zai)零下三十度到零上七十度的(de)(de)(de)條件下能正(zheng)常(chang)啟(qi)動工作(zuo)，那么(me)這(zhe)樣的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)還是可以(yi)用的(de)(de)(de)。安規(gui)測(ce)試(shi)：恒流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)耐壓測(ce)試(shi)，漏流(liu)(liu)符合安規(gui)要(yao)(yao)(yao)求(qiu)(qiu)(qiu)(qiu)。保(bao)護(hu)(hu)功能：包(bao)括(kuo)開路保(bao)護(hu)(hu)短路保(bao)護(hu)(hu)等，使得電(dian)(dian)(dian)(dian)路暢通(tong)工作(zuo)的(de)(de)(de)就行(xing)。

　　恒(heng)流(liu)電(dian)源的(de)(de)(de)(de)(de)(de)長(chang)(chang)期老化(hua)(hua)測試，此步驟(zou)分(fen)為三種(zhong)(zhong)方式(shi)。第一種(zhong)(zhong)正常(chang)老化(hua)(hua)，如果恒(heng)流(liu)電(dian)源一個月以(yi)上不(bu)出(chu)故(gu)障(zhang)，無燒(shao)毀，各(ge)參(can)數穩定(ding)(ding)，那(nei)(nei)么這樣的(de)(de)(de)(de)(de)(de)電(dian)路還(huan)是(shi)安全的(de)(de)(de)(de)(de)(de)。第二種(zhong)(zhong)叫(jiao)做間歇性老化(hua)(hua)，恒(heng)流(liu)電(dian)源在帶負載的(de)(de)(de)(de)(de)(de)情(qing)況下，不(bu)能通(tong)電(dian)/斷電(dian)測試電(dian)源的(de)(de)(de)(de)(de)(de)抗沖擊(ji)性能，如果不(bu)出(chu)特別大的(de)(de)(de)(de)(de)(de)故(gu)障(zhang)，電(dian)源沒有燒(shao)毀或發生其他的(de)(de)(de)(de)(de)(de)事故(gu)，各(ge)項參(can)數穩定(ding)(ding)，那(nei)(nei)么就是(shi)合格的(de)(de)(de)(de)(de)(de)。第三種(zhong)(zhong)加(jia)速老化(hua)(hua)，將恒(heng)流(liu)電(dian)源放置于高(gao)溫試驗箱(xiang)內帶負載長(chang)(chang)期工作，檢(jian)驗其各(ge)項性能是(shi)否穩定(ding)(ding)，如果是(shi)穩定(ding)(ding)的(de)(de)(de)(de)(de)(de)那(nei)(nei)也(ye)是(shi)極好的(de)(de)(de)(de)(de)(de)。

　　測(ce)(ce)試(shi)(shi)恒(heng)(heng)流電(dian)(dian)源(yuan)(yuan)老(lao)化方法有(you)以(yi)下(xia)幾(ji)種(zhong)(zhong):第(di)一種(zhong)(zhong)，基本參(can)(can)數測(ce)(ce)試(shi)(shi):將(jiang)恒(heng)(heng)流電(dian)(dian)源(yuan)(yuan)輸出端接(jie)LED負載，同(tong)時將(jiang)一只電(dian)(dian)流表串接(jie)其中，測(ce)(ce)試(shi)(shi)輸出的(de)電(dian)(dian)壓。看一下(xia)參(can)(can)數測(ce)(ce)試(shi)(shi)儀的(de)電(dian)(dian)壓大小等相關情(qing)況。第(di)二種(zhong)(zhong)是(shi)保(bao)護功能(neng)測(ce)(ce)試(shi)(shi): LED恒(heng)(heng)流電(dian)(dian)源(yuan)(yuan)的(de)保(bao)護功能(neng)是(shi)非常(chang)重(zhong)要的(de)，有(you)保(bao)護電(dian)(dian)路(lu)就(jiu)能(neng)安全暢行。開路(lu)保(bao)護：就(jiu)是(shi)電(dian)(dian)路(lu)LED斷開數秒后，再(zai)重(zhong)新接(jie)通LED，而短路(lu)保(bao)護也差不多。測(ce)(ce)試(shi)(shi)所需要設備儀器器件：手工測(ce)(ce)試(shi)(shi)不需要附(fu)加(jia)什么設備。第(di)三(san)種(zhong)(zhong)高(gao)(gao)低溫(wen)測(ce)(ce)試(shi)(shi): 高(gao)(gao)低溫(wen)測(ce)(ce)試(shi)(shi)主要檢測(ce)(ce)LED恒(heng)(heng)流電(dian)(dian)源(yuan)(yuan)在(zai)惡劣的(de)環境下(xia)是(shi)否能(neng)長正常(chang)啟動(dong)，如果高(gao)(gao)低溫(wen)下(xia)電(dian)(dian)源(yuan)(yuan)能(neng)夠正常(chang)啟動(dong)工作那就(jiu)是(shi)很好的(de)。

　　現在(zai)你知(zhi)道怎么檢測恒流電源是(shi)否老化了吧，不(bu)妨(fang)動手試一下。
