摘要
用于超导磁体冷却回路和电回路绝缘的绝缘子是EAST超导托卡马克装置中一个关键部件,在装置实际运行过程中它必须经受在一定的弯矩和拉力的动态情况下高电压和高内气压的考验。该文主要利用有限元程序对绝缘子力学性能、热学性能和电性能进行了分析与计算,并根据低温实验对绝缘子性能进行了进一步的研究。
Insulators are the key parts of the EAST Superconducting Tokamak, which are used to insulate all cryogenic supply lines and the conductor end of the winding. During all operation modes, insulators have to accept the challenge of the high voltage and hydraulic pressure, simultaneously they are loaded with bending moment and force. The mechanics behavior analysis and thermal analysis including electrical analysis for insulators using finite clement method are introduced in this paper. Also, we carry out cryogenic experiments for further study of insulators.
