| 摘 要： | 从理论和应用的观点讨论了电压等级35kV及以下的交联聚乙烯电缆耐压和局部放电试验时，杯型终端中使用氟里昂与水两种液体介质来替代单一氟里昂液体介质的新方法。利用时域有限元方法在理论上分析了该方法的可行性，并且试验验证了该方法的正确性。新方法能节约氟里昂，更重要的是能够减少对大气环境的污染。

| Abstract: | A novel method of which Freon and water are used to replace the single Freon in cup-tester is presented in this paper both from a theoretical and a practical point of view,when withstanding voltage and partial discharge tests are carried out on the XLPE cable voltage up to35kV.Feasibility of the method is analyzed from a theoretical view by time domain finite element,and then validity of the method is attained by experiment.The new method can save Freon,more important can reduce the air pollution. |
