鋁殼是(shi)由(you)鋁粒沖壓(ya)或鋁片擠壓(ya)而成(cheng)的圓筒形容 器，作為(wei)電容器密(mi)封之(zhi)外(wai)殼用。

電容(rong)器(qi)內部(bu)因使(shi)用(yong)之異(yi)常會(hui)因電流發熱而(er)產生(sheng)氣體(ti)造成(cheng)電容(rong)器(qi)內部(bu)壓(ya)(ya)力(li)增大產生(sheng)，所以(yi)直徑大于(yu)6mm鋁(lv)殼(ke)底(di)部(bu)會(hui)設防爆(bao)口(VENT)，即(ji)在鋁(lv)殼(ke)底(di)部(bu)沖有“十”或“Y”“K”字(zi)溝(gou)槽(cao)，使(shi)之成(cheng)為鋁(lv)殼(ke)脆弱部(bu)分(fen)，而(er)當(dang)內部(bu)壓(ya)(ya)力(li)超過規格值時(shi)，此(ci)防爆(bao)溝(gou)槽(cao)便(bian)會(hui)裂開，使(shi)壓(ya)(ya)力(li)排出防止造成(cheng)。

鋁殼不良狀況：

壓痕、污染、切口毛刺大、切口未平、鋁殼穿孔(kong)、殼厚不均等。

無(wu)論電(dian)(dian)容器(qi)(qi)(qi)在電(dian)(dian)子技術哪個領域(yu)中(zhong)(zhong)使(shi)用(yong)，都希望(wang)所用(yong)元件滿足性能要求，不會輕(qing)易受損，達到(dao)(dao)延長使(shi)用(yong)壽命的目的。在電(dian)(dian)路設計時，應對電(dian)(dian)解電(dian)(dian)容器(qi)(qi)(qi)的性能有更深(shen)入的了解，做(zuo)到(dao)(dao)心中(zhong)(zhong)有數(shu)，不要使(shi)電(dian)(dian)容器(qi)(qi)(qi)一(yi)直(zhi)處于工作(zuo)狀態。具體(ti)從(cong)以下幾(ji)個方面來考慮。

l降低所處環境溫度

降(jiang)低(di)所處(chu)(chu)環境(jing)溫(wen)(wen)度，使(shi)電(dian)(dian)(dian)(dian)容器(qi)不在上限類別溫(wen)(wen)度下工(gong)(gong)作(zuo)，另(ling)(ling)外還要(yao)考慮電(dian)(dian)(dian)(dian)容器(qi)本身發熱影(ying)響，這(zhe)(zhe)(zhe)一點對(dui)液體電(dian)(dian)(dian)(dian)解(jie)質類型產品尤為重要(yao)。如果產生高溫(wen)(wen)，會使(shi)漏電(dian)(dian)(dian)(dian)流劇(ju)增，氣體增多，使(shi)外殼處(chu)(chu)于內壓急增狀(zhuang)態；另(ling)(ling)外高溫(wen)(wen)能使(shi)電(dian)(dian)(dian)(dian)解(jie)液加速干涸，相對(dui)縮短產品壽命。因此對(dui)長壽命要(yao)求的(de)產品來說(shuo)，工(gong)(gong)作(zuo)溫(wen)(wen)度應控(kong)制在50℃以下，這(zhe)(zhe)(zhe)樣相應的(de)壽命約可(ke)提(ti)高1～2個(ge)數量級。例如在45℃以可(ke)工(gong)(gong)作(zuo)20年(nian)的(de)計(ji)算機電(dian)(dian)(dian)(dian)容器(qi)，在85℃下則只能工(gong)(gong)作(zuo)1～2年(nian)。如需要(yao)應用在上限類別溫(wen)(wen)度（85℃），則電(dian)(dian)(dian)(dian)容器(qi)芯子中(zhong)心溫(wen)(wen)度應不超過95℃，而且還得視所選(xuan)擇工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)解(jie)液的(de)性(xing)質而定(ding)。這(zhe)(zhe)(zhe)種高溫(wen)(wen)影(ying)響對(dui)固體鉭電(dian)(dian)(dian)(dian)容器(qi)來說(shuo)，不如鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容器(qi)那么嚴重，但肯定(ding)也是有害(hai)的(de)。

l降低(di)額定電壓(ya)的使用上限

降低(di)額定電(dian)壓的(de)使用上限，也就是降低(di)介質氧化膜(mo)的(de)工作場(chang)強，對鋁電(dian)容(rong)器(qi)將(jiang)適用。降負荷一(yi)半后，電(dian)容(rong)器(qi)的(de)壽命能提高2個數量級之多(duo)。

實(shi)際上鋁氧(yang)化膜如出現損傷和被腐蝕，修(xiu)補(bu)氧(yang)化膜拜出只能(neng)在的工(gong)作電壓下進行，局部難于恢復到原始形成電壓值下的氧(yang)化膜厚(hou)度，所以過分降低工(gong)作電壓，對鋁電解電容器也并不(bu)是的措施(shi)。
