如何延長貫穿電容的使用壽命？

來源：jincuigu.com.cn 發布時間：2020-05-08 返回
　　選擇高質量貫穿(chuan)電(dian)容(rong)
　　
　　貫穿電容的質量較差，容易發生各種故障，從而縮短了貫穿電容的壽命。如果公司選擇使用高質量的貫穿電容，則可以大大降低故障率，并增加實際使用時間，并且還可以大大擴展。

　　避免過(guo)電壓(ya)和過(guo)電流操作
　　
　　當貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)過(guo)壓工(gong)(gong)(gong)作時，貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)的內部放電(dian)(dian)擊穿(chuan)將增(zeng)加(jia)貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)絕緣介(jie)質的損耗，從(cong)(cong)而縮短貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)的壽(shou)命；當功率貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)以(yi)過(guo)電(dian)(dian)流工(gong)(gong)(gong)作時，大電(dian)(dian)流將導致貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)的內部溫度升(sheng)高，從(cong)(cong)而使(shi)(shi)貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)加(jia)速。絕緣材(cai)料(liao)會發生熱(re)老化，從(cong)(cong)而縮短其(qi)(qi)使(shi)(shi)用壽(shou)命。因(yin)此，當功率貫(guan)(guan)穿(chuan)電(dian)(dian)容(rong)(rong)工(gong)(gong)(gong)作時，避(bi)免(mian)其(qi)(qi)因(yin)過(guo)壓和(he)過(guo)電(dian)(dian)流而工(gong)(gong)(gong)作，可以(yi)延長其(qi)(qi)使(shi)(shi)用壽(shou)命。
　　
　　確保室溫合適
　　
　　環(huan)境(jing)溫(wen)度(du)過高會加(jia)速功率貫(guan)穿(chuan)電容(rong)絕緣的熱老化(hua)；環(huan)境(jing)溫(wen)度(du)太低會加(jia)速貫(guan)穿(chuan)電容(rong)的介電老化(hua)。因此，貫(guan)穿(chuan)電容(rong)的工作環(huan)境(jing)溫(wen)度(du)是(shi)合(he)適的，并且貫(guan)穿(chuan)電容(rong)的使用(yong)壽命(ming)也可以(yi)延長。
　　
　　及時控(kong)制電網中是否存在諧波(bo)。
　　
　　諧(xie)波(bo)會(hui)影響電(dian)(dian)氣設(she)備，諧(xie)波(bo)源也會(hui)與貫穿電(dian)(dian)容(rong)(rong)并聯形(xing)成諧(xie)振。因此，當貫穿電(dian)(dian)容(rong)(rong)有時與諧(xie)波(bo)一起(qi)使用(yong)時，需(xu)要諧(xie)波(bo)控制以延(yan)長(chang)貫穿電(dian)(dian)容(rong)(rong)的壽(shou)命。
　　
　　通過(guo)選擇好(hao)的(de)貫(guan)穿電容來防止過(guo)電壓，過(guo)電流和過(guo)熱操作(zuo)，可以有效地(di)延長貫(guan)穿電容的(de)使用壽命，從而可以長時間穩定工(gong)作(zuo)。
