絕緣耐壓試驗(yàn)分為<\/span>直流耐壓試驗(yàn)<\/span><\/strong>和<\/span>交流耐壓試驗(yàn)<\/span><\/strong>兩種。過去在進(jìn)行電纜耐壓試驗(yàn)時(shí)都采用直流耐壓試驗(yàn)。在1980年左右，國外電力部門發(fā)現(xiàn)直流耐壓試驗(yàn)對(duì)橡塑絕緣是無效的且具有危害性。我國在九十年代開始研究和實(shí)踐交流耐壓試驗(yàn)技術(shù)。經(jīng)過20多年的研究和實(shí)踐，世界各國紛紛采用交流耐壓試驗(yàn)代替直流耐壓試驗(yàn)。國內(nèi)外有關(guān)標(biāo)準(zhǔn)機(jī)構(gòu)也對(duì)于高壓電纜的試驗(yàn)方法作出了更改和修訂。1997年CIGRI國際大電網(wǎng)工作會(huì)議對(duì)目前采用的直流耐壓試驗(yàn)方法提出疑議，并推薦使用工頻及近似工頻（30-300HZ）的交流試驗(yàn)方法，在全世界范圍內(nèi)推廣應(yīng)用。我國的華北電力集團(tuán)，廣東，江蘇，浙江，福建，安徽等電網(wǎng)已先后頒發(fā)《試驗(yàn)規(guī)程》，強(qiáng)制規(guī)定用交流耐壓試驗(yàn)代替直流耐壓試驗(yàn)。在我國電網(wǎng)相對(duì)發(fā)達(dá)的省份，交流耐壓試驗(yàn)已經(jīng)成為強(qiáng)制性標(biāo)準(zhǔn)。其它地區(qū)的試驗(yàn)規(guī)程也在起草和醞釀中。<\/span>交流耐壓試驗(yàn)取代傳統(tǒng)直流耐壓試驗(yàn)已是大勢所趨。<\/span><\/strong> <\/p>
