絕緣耐壓試驗分為<\/span>直流耐壓試驗<\/span><\/strong>和<\/span>交流耐壓試驗<\/span><\/strong>兩種。過去在進行電纜耐壓試驗時都采用直流耐壓試驗。在1980年左右，國外電力部門發(fā)現直流耐壓試驗對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踐交流耐壓試驗技術。經過20多年的研究和實踐，世界各國紛紛采用交流耐壓試驗代替直流耐壓試驗。國內外有關標準機構也對于高壓電纜的試驗方法作出了更改和修訂。1997年CIGRI國際大電網工作會議對目前采用的直流耐壓試驗方法提出疑議，并推薦使用工頻及近似工頻（30-300HZ）的交流試驗方法，在全世界范圍內推廣應用。我國的華北電力集團，廣東，江蘇，浙江，福建，安徽等電網已先后頒發(fā)《試驗規(guī)程》，強制規(guī)定用交流耐壓試驗代替直流耐壓試驗。在我國電網相對發(fā)達的省份，交流耐壓試驗已經成為強制性標準。其它地區(qū)的試驗規(guī)程也在起草和醞釀中。<\/span>交流耐壓試驗取代傳統(tǒng)直流耐壓試驗已是大勢所趨。<\/span><\/strong> <\/p>
