l選擇漏電流值較小(xiao)的電容器

作(zuo)為長壽(shou)命使用(yong)的(de)電(dian)(dian)解(jie)電(dian)(dian)容(rong)器，除了以上4點外加因素的(de)考慮外，在選用(yong)中(zhong)還要(yao)選擇在同(tong)類型中(zhong)漏(lou)電(dian)(dian)流(liu)特別小的(de)電(dian)(dian)容(rong)器。這表明它具有較高(gao)質(zhi)量的(de)氧(yang)化(hua)膜和合適的(de)工作(zuo)電(dian)(dian)解(jie)質(zhi)。一(yi)旦環境溫(wen)度(du)較高(gao)，相應的(de)漏(lou)電(dian)(dian)流(liu)增(zeng)(zeng)加就(jiu)較慢。否(fou)則在互(hu)為影響的(de)情(qing)況下，當漏(lou)電(dian)(dian)流(liu)劇增(zeng)(zeng)，內部溫(wen)度(du)將上升，反過來使漏(lou)電(dian)(dian)流(liu)再上升，一(yi)直(zhi)惡化(hua)直(zhi)至失去熱平衡而破壞(huai)為止(zhi)。
