氦气状态对超导托卡马克室温绝缘子电性能影响实验研究

Influence of helium state on electrical properties of room temperature insulation breaks for superconducting tokamak

为了解不同氦气状态对超导托卡马克室温绝缘子电性能的影响,建造了室温绝缘子氦气状态下电性能测试平台。利用该平台,在静态氦气和氦气流速为0.65g·s^(-1)状态下进行了室温绝缘子高电压-漏电流实验。实验结果表明,两种氦气状态下室温绝缘子均满足使用要求。

To reveal the influence of helium state on the electrical properties of room temperature insulation breaks （RTIB） for a superconducting tokamak, a test platform used to perform high voltage-leakage current experiments was established. And using the test platform the high voltage-leakage current experiments of room temperature insulation breaks for a superconducting tokamak under static and flow rate of 0.65g.s-1 helium gas environment were performed. The results show that the room temperature insulation breaks for a superconducting tokamak under the two Helium states can fulfill the operating requirements.
