摘　　要：超导电力装置具有载流能力大、损耗低和体积小的优点,传输容量将比常规装置高3～5倍,其本身的焦耳热损耗几乎为0。超导电力装置中,其绝缘性能对于超导装置的稳定运行起着十分重要的作用,随着超导装置电压等级的提高,对绝缘性能的要求也随之提升。本文用PPLP、100HN、100CR、T410、T418绝缘材料,测试了它们的击穿性场强及沿面闪络电压,并对它们的击穿及沿闪性能进行对比分析。HTS equipment has great current -carrying capacity and the advantages ot small size and low dmsipation,its transmission capacity will be 3-5times higher than conventional equipment and the ontology joule heat loss of the cable is almost zero.For Superconducting cable,its insulation performance for the stable operation of superconducting equipment plays a very important role.With the improvement of voltage grade of superconducting equipment,the performance requirements of the insula- tion also are optimized.In the paper,the insulation was made by using 100HN,100CR,PPLP,T410and T418,their breakdown strength and flashover were tested and the performances of their breakdown and flashover were compared.
