國內外(wai)有關部門為什么廣泛推薦采用交流耐壓取代直(zhi)流耐壓?
隨(sui)著國民經濟的(de)(de)(de)發展以及(ji)城網供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)等級的(de)(de)(de)提高(gao)，交(jiao)(jiao)聯(lian)(lian)聚乙烯絕緣電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(XLPE)以其(qi)合(he)理的(de)(de)(de)工藝和結構，優良的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)氣(qi)性能和安全(quan)可靠(kao)的(de)(de)(de)運(yun)行特(te)點，在(zai)國內(nei)外獲得(de)越來越廣泛的(de)(de)(de)使用。尤(you)其(qi)在(zai)高(gao)壓(ya)輸(shu)電(dian)(dian)(dian)(dian)(dian)領域更取得(de)了巨(ju)大的(de)(de)(de)進展。與充(chong)油電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)相比，交(jiao)(jiao)聯(lian)(lian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)敷設安裝(zhuang)方便，運(yun)行維護簡單，不存(cun)在(zai)油的(de)(de)(de)淌流問題。但是(shi)，近年來的(de)(de)(de)運(yun)行和研究表明，交(jiao)(jiao)聯(lian)(lian)聚乙烯電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)絕緣在(zai)運(yun)行中易產(chan)生樹(shu)枝(zhi)化放(fang)電(dian)(dian)(dian)(dian)(dian)，造成(cheng)絕緣老化破壞，嚴重(zhong)(zhong)地影(ying)(ying)響(xiang)了交(jiao)(jiao)聯(lian)(lian)聚乙烯絕緣電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)使用壽命。因此，充(chong)分(fen)認識交(jiao)(jiao)聯(lian)(lian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)絕緣特(te)性，及(ji)時(shi)有(you)效(xiao)地發現和預防絕緣中存(cun)在(zai)的(de)(de)(de)某些缺陷，對保障設備(bei)乃至(zhi)系統的(de)(de)(de)安全(quan)運(yun)行具有(you)十分(fen)重(zhong)(zhong)要的(de)(de)(de)意義。闡(chan)述了影(ying)(ying)響(xiang)交(jiao)(jiao)聯(lian)(lian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)絕緣的(de)(de)(de)主要因素以及(ji)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)交(jiao)(jiao)接試驗(yan)原理，認為在(zai)現場對交(jiao)(jiao)聯(lian)(lian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)實施交(jiao)(jiao)流耐壓(ya)試驗(yan)是(shi)必要和可行的(de)(de)(de)。
