電(dian)容式套管
的電(dian)(dian)(dian)(dian)容心子(zi)用(yong)膠紙(zhi)制(zhi)造(zao)時,機械強度(du)高(gao),可(ke)以任何角度(du)安裝,抗潮(chao)(chao)氣性(xing)能(neng)好(hao),結(jie)構和(he)維修簡單,可(ke)不用(yong)下套管(guan)(guan),還(huan)可(ke)將心子(zi)下端車削(xue)成(cheng)(cheng)短尾式(shi),縮(suo)小(xiao)其尺寸(cun)。缺點是(shi)在高(gao)電(dian)(dian)(dian)(dian)壓等級時,絕級材料和(he)工藝要求(qiu)較高(gao),心子(zi)中不易消除氣隙(xi),以致造(zao)成(cheng)(cheng)局(ju)部放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓低(di)。膠紙(zhi)電(dian)(dian)(dian)(dian)容式(shi)套管(guan)(guan)由(you)于介質損耗偏高(gao)和(he)局(ju)部放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓低(di)等問題,已逐漸為油紙(zhi)電(dian)(dian)(dian)(dian)容式(shi)套管(guan)(guan)所取代(dai)。采用(yong)油紙(zhi)作電(dian)(dian)(dian)(dian)容心子(zi),一般(ban)要有下瓷套,下部尺寸(cun)較大,對潮(chao)(chao)氣比較敏感(gan),密封要求(qiu)高(gao);優(you)點是(shi)絕緣材料和(he)工藝易于解決(jue),介質損耗小(xiao),局(ju)部放(fang)電(dian)(dian)(dian)(dian)性(xing)能(neng)好(hao)。70年代(dai)開(kai)始,中國已廣(guang)泛使用(yong)110~500千(qian)伏超高(gao)壓油紙(zhi)電(dian)(dian)(dian)(dian)容式(shi)套管(guan)(guan)。 80年代(dai)中國還(huan)發展了一種膠浸(jin)(jin)紙(zhi)套管(guan)(guan),其電(dian)(dian)(dian)(dian)容心子(zi)是(shi)以絕緣紙(zhi)卷制(zhi)成(cheng)(cheng)心子(zi)后用(yong)合成(cheng)(cheng)樹脂真空浸(jin)(jin)漬,再經熱固化處理。其性(xing)能(neng)兼有膠紙(zhi)和(he)油紙(zhi)電(dian)(dian)(dian)(dian)容式(shi)套管(guan)(guan)的優(you)點。
