國內外有關部門為什么(me)廣泛推薦采用變頻串聯諧振耐壓裝置取(qu)代直流耐壓試驗?
隨(sui)著國民經(jing)濟的(de)(de)(de)發展(zhan)以及(ji)(ji)城(cheng)網供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓等級的(de)(de)(de)提高，交(jiao)(jiao)聯(lian)聚(ju)乙烯(xi)絕(jue)(jue)緣(yuan)(yuan)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)(XLPE)以其合(he)理(li)的(de)(de)(de)工藝和結構，優良的(de)(de)(de)電(dian)(dian)(dian)(dian)氣(qi)性能和安(an)全(quan)可靠的(de)(de)(de)運(yun)(yun)(yun)行特(te)點(dian)，在(zai)(zai)國內外獲得(de)越來越廣泛(fan)的(de)(de)(de)使用。尤(you)其在(zai)(zai)高壓輸電(dian)(dian)(dian)(dian)領(ling)域(yu)更取得(de)了(le)巨大的(de)(de)(de)進展(zhan)。與充油電(dian)(dian)(dian)(dian)纜(lan)(lan)相比，交(jiao)(jiao)聯(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)敷設安(an)裝方便(bian)，運(yun)(yun)(yun)行維護(hu)簡單，不(bu)存在(zai)(zai)油的(de)(de)(de)淌流問題。但是，近年來的(de)(de)(de)運(yun)(yun)(yun)行和研(yan)究表(biao)明，交(jiao)(jiao)聯(lian)聚(ju)乙烯(xi)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)絕(jue)(jue)緣(yuan)(yuan)在(zai)(zai)運(yun)(yun)(yun)行中(zhong)易產生樹枝化放電(dian)(dian)(dian)(dian)，造成絕(jue)(jue)緣(yuan)(yuan)老化破(po)壞，嚴(yan)重地(di)影(ying)響了(le)交(jiao)(jiao)聯(lian)聚(ju)乙烯(xi)絕(jue)(jue)緣(yuan)(yuan)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)使用壽命。因此，充分認識(shi)交(jiao)(jiao)聯(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)絕(jue)(jue)緣(yuan)(yuan)特(te)性，及(ji)(ji)時有效地(di)發現(xian)(xian)和預防(fang)絕(jue)(jue)緣(yuan)(yuan)中(zhong)存在(zai)(zai)的(de)(de)(de)某些缺陷，對保障(zhang)設備乃至系(xi)統的(de)(de)(de)安(an)全(quan)運(yun)(yun)(yun)行具有十分重要(yao)的(de)(de)(de)意(yi)義。闡(chan)述(shu)了(le)影(ying)響交(jiao)(jiao)聯(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)絕(jue)(jue)緣(yuan)(yuan)的(de)(de)(de)主要(yao)因素以及(ji)(ji)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)交(jiao)(jiao)接(jie)試驗原理(li)，認為在(zai)(zai)現(xian)(xian)場對交(jiao)(jiao)聯(lian)電(dian)(dian)(dian)(dian)纜(lan)(lan)實(shi)施交(jiao)(jiao)流耐(nai)壓試驗是必(bi)要(yao)和可行的(de)(de)(de)。
