用于超导托卡马克的复合材料绝缘子电性能研究

Study on electrical performance of composite isolators for superconducting Tokamak

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 safe operation of isolators for superconducting Tokamak, the electrical field analysis of side to side and in -bulk modes were performed based on finite element technology. Furthermore, the high voltage -leakage current tests were performed based on the results of electrical field analysis. The results indicate the electrical properties of the insulator can meet the requirements when the pressure of the helium gas is 0.1 MPa and the voltage is DC 8kV.
