在這(zhe)方面，鋁(lv)電(dian)解(jie)(jie)有(you)(you)明顯的(de)缺點，鋁(lv)電(dian)解(jie)(jie)的(de)貯(zhu)存期愈長，氧化(hua)膜(mo)(mo)被損(sun)傷的(de)可(ke)(ke)(ke)能(neng)(neng)性(xing)愈大(da)。這(zhe)是(shi)由于其(qi)中的(de)雜(za)質(zhi)金屬離子(zi)與鋁(lv)箔組成微電(dian)池的(de)作(zuo)用以(yi)及(ji)(ji)含水(shui)較(jiao)多的(de)工作(zuo)電(dian)解(jie)(jie)液(ye)對(dui)鋁(lv)氧化(hua)膜(mo)(mo)的(de)水(shui)合侵蝕。也(ye)可(ke)(ke)(ke)能(neng)(neng)其(qi)中的(de)溶質(zhi)對(dui)鋁(lv)氧化(hua)膜(mo)(mo)還有(you)(you)溶解(jie)(jie)破壞作(zuo)用，因為(wei)如果電(dian)解(jie)(jie)液(ye)PH值偏離中性(xing)很多，就(jiu)可(ke)(ke)(ke)能(neng)(neng)出現這(zhe)一(yi)現象，這(zhe)種現象稱為(wei)去形成作(zuo)用。另(ling)外，如產(chan)品本(ben)身結構(gou)密封性(xing)不(bu)好，則電(dian)解(jie)(jie)液(ye)成分有(you)(you)揮發損(sun)失甚(shen)至干涸的(de)可(ke)(ke)(ke)能(neng)(neng)，另(ling)外還會(hui)吸(xi)收外界潮氣(qi)等，更(geng)促進了(le)破壞的(de)加劇。所以(yi)在經過(guo)較(jiao)長時(shi)間(jian)的(de)貯(zhu)存后，一(yi)接(jie)上額(e)定電(dian)壓(ya)，漏電(dian)流(liu)很大(da)，而(er)(er)且在正常時(shi)間(jian)內(nei)降(jiang)得(de)很慢，氧化(hua)膜(mo)(mo)也(ye)會(hui)來不(bu)及(ji)(ji)修復，造成氧化(hua)膜(mo)(mo)更(geng)多部位(wei)的(de)擊穿，此時(shi)產(chan)品將發熱，即(ji)可(ke)(ke)(ke)能(neng)(neng)導致性(xing)損(sun)壞。但一(yi)般遇到(dao)這(zhe)種情況，可(ke)(ke)(ke)逐漸升壓(ya)，電(dian)容(rong)(rong)就(jiu)可(ke)(ke)(ke)以(yi)逐漸恢(hui)復正常 。總(zong)之，漏電(dian)流(liu)大(da)小是(shi)衡量電(dian)容(rong)(rong)性(xing)能(neng)(neng)及(ji)(ji)工藝過(guo)程是(shi)否合適和文明生(sheng)(sheng)產(chan)程度的(de)一(yi)個直接(jie)標志，任何原材料中的(de)雜(za)質(zhi)以(yi)及(ji)(ji)操作(zuo)中的(de)污染（灰塵(chen)、汗漬(zi)等），均有(you)(you)可(ke)(ke)(ke)能(neng)(neng)導致氧化(hua)膜(mo)(mo)生(sheng)(sheng)長不(bu)均以(yi)及(ji)(ji)膜(mo)(mo)上存在缺陷，而(er)(er)組成穩(wen)態漏電(dian)流(liu)的(de)主要部分---電(dian)子(zi)電(dian)流(liu)，就(jiu)是(shi)通過(guo)缺陷以(yi)及(ji)(ji)箔的(de)邊緣(yuan)而(er)(er)進行的(de)。

長城電(dian)(dian)(dian)器(qi)(qi)(qi)回(hui)收公司(si)上門回(hui)收各種(zhong)型(xing)號電(dian)(dian)(dian)解電(dian)(dian)(dian)容器(qi)(qi)(qi)，高低壓電(dian)(dian)(dian)容器(qi)(qi)(qi)，自愈式電(dian)(dian)(dian)容器(qi)(qi)(qi)，蓄電(dian)(dian)(dian)池，鎘鎳電(dian)(dian)(dian)瓶，電(dian)(dian)(dian)抗器(qi)(qi)(qi)，ME斷路器(qi)(qi)(qi)，智能閘，互感器(qi)(qi)(qi)，放(fang)點線圈(quan)，接觸器(qi)(qi)(qi)，空氣開關，電(dian)(dian)(dian)線電(dian)(dian)(dian)纜等庫存物資。以(yi)誠為本，信譽至上。回(hui)收，沒極限。歡迎來電(dian)(dian)(dian)洽談。

1、測電阻(zu)(zu)時(shi)(shi)，每(mei)換(huan)一次擋(dang)(dang)都(dou)要(yao)進行調(diao)零(ling)(ling)。調(diao)不到零(ling)(ling)時(shi)(shi)要(yao)更換(huan)新(xin)電池。測R先調(diao)零(ling)(ling)，換(huan)擋(dang)(dang)需調(diao)零(ling)(ling)。測量(liang)電阻(zu)(zu)時(shi)(shi)，應先將(jiang)轉換(huan)開關旋到電阻(zu)(zu)擋(dang)(dang)，把兩表(biao)筆短接，旋'Ω'調(diao)零(ling)(ling)電位器，使(shi)指(zhi)針(zhen)指(zhi)零(ling)(ling)歐后再測量(liang)。每(mei)次更換(huan)電阻(zu)(zu)擋(dang)(dang)時(shi)(shi)，都(dou)應重新(xin)調(diao)整歐姆零(ling)(ling)點；

2、萬用表使用完畢，應將轉換(huan)開關置于交流電壓的擋；

3、長期不使用，應將萬用表(biao)內部(bu)電池(chi)取出(chu)，以免電池(chi)腐蝕(shi)表(biao)內其它器(qi)件(jian)；

4，測量先看擋，不看不測量。每次拿起表筆準備測量時，務必再核對(dui)一下測量類別及量程選擇開關是否撥對(dui)位置。為了安全，必須養(yang)成這種習(xi)慣(guan)；

5、表盤應水平(ping)，讀數(shu)(shu)要(yao)對(dui)正。使用萬用表應水平(ping)旋轉，讀數(shu)(shu)時(shi)視線應正對(dui)著表針；

6、測(ce)(ce)R不帶(dai)電(dian)，測(ce)(ce)C先放(fang)電(dian)。嚴禁(jin)在(zai)被測(ce)(ce)電(dian)路帶(dai)點的(de)情況下測(ce)(ce)電(dian)阻。檢查(cha)電(dian)器設備上的(de)大容量(liang)電(dian)容器時，應先將電(dian)容器短路放(fang)電(dian)后再(zai)測(ce)(ce)量(liang)；

長城電(dian)器(qi)(qi)回收(shou)公司上(shang)門回收(shou)各種型(xing)號電(dian)解電(dian)容器(qi)(qi)，高低壓電(dian)容器(qi)(qi)，自愈式電(dian)容器(qi)(qi)，蓄電(dian)池，鎘鎳(nie)電(dian)瓶，電(dian)抗器(qi)(qi)，ME斷(duan)路器(qi)(qi)，智能閘，互感器(qi)(qi)，放點線(xian)圈，接觸器(qi)(qi)，空氣(qi)開關，電(dian)線(xian)電(dian)纜等庫存物(wu)資。以誠為本(ben)，信(xin)譽至(zhi)上(shang)。回收(shou)，沒極限(xian)。歡(huan)迎來電(dian)洽談(tan)。

因其(qi)低(di)成本的特點，鋁電解(jie)(jie)電容(rong)器(qi)回收公司一直都(dou)是電源的常(chang)用選擇。但是，它們壽命(ming)(ming)有限，且易受高溫和低(di)溫條件的影(ying)響。鋁電解(jie)(jie)電容(rong)器(qi)在浸透電解(jie)(jie)液(ye)(ye)的紙片兩面放(fang)置金屬薄片。這(zhe)種電解(jie)(jie)液(ye)(ye)會(hui)在電容(rong)器(qi)壽命(ming)(ming)期間蒸發，從而改變其(qi)電氣屬性。如果電容(rong)器(qi)失效，其(qi)會(hui)出(chu)(chu)現劇烈的反(fan)應：電容(rong)器(qi)中(zhong)形成壓(ya)力，迫使(shi)它釋放(fang)出(chu)(chu)、腐蝕性氣體。

電(dian)(dian)(dian)解質蒸發(fa)的(de)(de)速度(du)與電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)溫(wen)度(du)密切相關。工(gong)作(zuo)溫(wen)度(du)每下降 10 攝氏度(du)，電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)壽(shou)命(ming)(ming)延長一(yi)倍。電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)額(e)定壽(shou)命(ming)(ming)通常為(wei)(wei)在(zai)其額(e)定溫(wen)度(du)下得出的(de)(de)結果(guo)。典(dian)型的(de)(de)額(e)定壽(shou)命(ming)(ming)為(wei)(wei) 105 攝氏度(du)下 1000 小(xiao)時。選擇這(zhe)些電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)用(yong)于圖 1 所(suo)示(shi) LED 燈(deng)泡(pao) 等 長壽(shou) 命(ming)(ming)應(ying) 用(yong) 時（ LED 的(de)(de) 壽(shou)命(ming)(ming) 為(wei)(wei) 25000 小(xiao)時），電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)的(de)(de)壽(shou)命(ming)(ming)便成了問題。要想達到 25000 小(xiao)時壽(shou)命(ming)(ming)，這(zhe)種電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)要求工(gong)作(zuo)溫(wen)度(du)不超(chao)過 65 攝氏度(du)。這(zhe)種工(gong)作(zuo)溫(wen)度(du)特別(bie)具有(you)(you)挑戰性，因為(wei)(wei)在(zai)這(zhe)種應(ying)用(yong)中，環境溫(wen)度(du)會(hui)超(chao)出 125 攝氏度(du)。市場上有(you)(you)一(yi)些高額(e)定溫(wen)度(du)的(de)(de)電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)，但(dan)是在(zai)大多數情(qing)況下，鋁(lv)電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)都將成為(wei)(wei) LED 燈(deng)泡(pao)壽(shou)命(ming)(ming)的(de)(de)瓶(ping)頸組件。
