        （1）绝缘(yuan)(yuan)作(zuo)用(yong)(yong)(yong)(yong)：变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)油(you)(you)(you)(you)(you)具有比(bi)空气(qi)高(gao)得多的(de)(de)(de)(de)(de)(de)(de)(de)绝缘(yuan)(yuan)强度(du)(du)(du)。绝缘(yuan)(yuan)材料(liao)浸在油(you)(you)(you)(you)(you)中(zhong)，不(bu)仅可(ke)提(ti)高(gao)绝缘(yuan)(yuan)强度(du)(du)(du)，而(er)且还可(ke)免(mian)(mian)受(shou)潮气(qi)的(de)(de)(de)(de)(de)(de)(de)(de)侵蚀。（2）散(san)热(re)(re)作(zuo)用(yong)(yong)(yong)(yong)：变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)油(you)(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)比(bi)热(re)(re)大，常(chang)用(yong)(yong)(yong)(yong)作(zuo)冷(leng)却剂。变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)运行时产(chan)(chan)生的(de)(de)(de)(de)(de)(de)(de)(de)热(re)(re)量(liang)(liang)使(shi)靠(kao)近铁芯和(he)(he)(he)绕组(zu)的(de)(de)(de)(de)(de)(de)(de)(de)油(you)(you)(you)(you)(you)受(shou)热(re)(re)膨胀上(shang)(shang)升，通过(guo)油(you)(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)上(shang)(shang)下对流(liu)，热(re)(re)量(liang)(liang)通过(guo)散(san)热(re)(re)器(qi)(qi)散(san)出，保证变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)正常(chang)运行。（3）消弧(hu)(hu)作(zuo)用(yong)(yong)(yong)(yong)：在油(you)(you)(you)(you)(you)断路器(qi)(qi)和(he)(he)(he)变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)(de)有载调压(ya)(ya)(ya)(ya)(ya)开关上(shang)(shang)，触头(tou)切换(huan)时会产(chan)(chan)生电弧(hu)(hu)。由(you)于(yu)(yu)变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)油(you)(you)(you)(you)(you)导热(re)(re)性(xing)能(neng)(neng)好，且在电弧(hu)(hu)的(de)(de)(de)(de)(de)(de)(de)(de)高(gao)温(wen)作(zuo)用(yong)(yong)(yong)(yong)下能(neng)(neng)分触了大量(liang)(liang)气(qi)体，产(chan)(chan)生较大压(ya)(ya)(ya)(ya)(ya)力，从而(er)提(ti)高(gao)了介质(zhi)的(de)(de)(de)(de)(de)(de)(de)(de)灭弧(hu)(hu)性(xing)能(neng)(neng)，使(shi)电弧(hu)(hu)很(hen)快(kuai)熄(xi)灭。变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)油(you)(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)性(xing)能(neng)(neng)要求：（1）密(mi)度(du)(du)(du)尽量(liang)(liang)小，以便于(yu)(yu)油(you)(you)(you)(you)(you)中(zhong)水(shui)分和(he)(he)(he)杂质(zhi)沉淀。（2）粘度(du)(du)(du)要适中(zhong)，太(tai)大会影响对流(liu)散(san)热(re)(re)，太(tai)小又会降(jiang)低(di)(di)闪(shan)点(dian)。（3）闪(shan)点(dian)应(ying)尽量(liang)(liang)高(gao)，一般不(bu)应(ying)低(di)(di)于(yu)(yu)135℃。（4）凝固(gu)点(dian)应(ying)尽量(liang)(liang)低(di)(di)。（5）酸、碱、硫、灰分等(deng)杂质(zhi)含量(liang)(liang)越低(di)(di)越好，以尽量(liang)(liang)避免(mian)(mian)它们对绝缘(yuan)(yuan)材料(liao)、导线、油(you)(you)(you)(you)(you)箱等(deng)的(de)(de)(de)(de)(de)(de)(de)(de)腐(fu)蚀。（6）氧(yang)化程(cheng)(cheng)度(du)(du)(du)不(bu)能(neng)(neng)太(tai)高(gao)。氧(yang)化程(cheng)(cheng)度(du)(du)(du)通常(chang)用(yong)(yong)(yong)(yong)酸价表示，它指(zhi)吸收1克油(you)(you)(you)(you)(you)中(zhong)的(de)(de)(de)(de)(de)(de)(de)(de)游离(li)酸所(suo)需(xu)的(de)(de)(de)(de)(de)(de)(de)(de)氢氧(yang)化钾量(liang)(liang)（毫(hao)克）。（7）安(an)(an)定度(du)(du)(du)不(bu)应(ying)太(tai)低(di)(di)，安(an)(an)定度(du)(du)(du)通常(chang)用(yong)(yong)(yong)(yong)酸价试验的(de)(de)(de)(de)(de)(de)(de)(de)沉淀物表示，它代表油(you)(you)(you)(you)(you)抗老化的(de)(de)(de)(de)(de)(de)(de)(de)能(neng)(neng)力。为什么高(gao)压(ya)(ya)(ya)(ya)(ya)变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)要用(yong)(yong)(yong)(yong)到(dao)(dao)油(you)(you)(you)(you)(you)？电力变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)里面(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)(de)油(you)(you)(you)(you)(you)是(shi)特制的(de)(de)(de)(de)(de)(de)(de)(de)“变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)油(you)(you)(you)(you)(you)”，其作(zuo)用(yong)(yong)(yong)(yong)是(shi)增强绝缘(yuan)(yuan)和(he)(he)(he)冷(leng)却。变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)产(chan)(chan)生的(de)(de)(de)(de)(de)(de)(de)(de)热(re)(re)量(liang)(liang)由(you)油(you)(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)热(re)(re)循环(huan)带到(dao)(dao)外(wai)面(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)(de)散(san)热(re)(re)管(guan)（片）散(san)到(dao)(dao)外(wai)面(mian)(mian)，大型的(de)(de)(de)(de)(de)(de)(de)(de)变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)还有风(feng)扇为油(you)(you)(you)(you)(you)降(jiang)温(wen)。现在变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)(de)制作(zuo)技术和(he)(he)(he)新型绝缘(yuan)(yuan)材料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)，一些中(zhong)小型的(de)(de)(de)(de)(de)(de)(de)(de)电力变(bian)(bian)压(ya)(ya)(ya)(ya)(ya)器(qi)(qi)也可(ke)以作(zuo)成不(bu)用(yong)(yong)(yong)(yong)。

        变压器油在使用一段时间后有水分，气体，杂质，变压器油耐压值降低，所以需要真空滤油机来处理，我们推荐使用新澳门3559com 真(zhen)空滤(lv)油机，具有快(kuai)速脱水，脱气体，脱杂质的功能，提变(bian)压(ya)器油高(gao)耐压(ya)值(zhi)。
