为保证用于超导托卡马克的复合材料绝缘子安全运行,基于有限元法对其开展了端对本体和端对端两种电极连接方式的电场分析,在此基础上进行了直流高电压-漏电流实验。结果表明,绝缘子在氦气压力0.1MPa、直流电压8 k V下的电性能满足使用要求。
In order to ensure the safe operation of superconducting tokamak composite insulators, the electric field analysis of end-to-end and end-to-end two electrode connections was carried out based on the finite element method. Based on this, the DC high voltage- Leakage current experiment. The results show that the electrical properties of the insulator under helium pressure 0.1MPa, DC voltage 8k V meet the requirements.
