摘要:

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。

Abstract:

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.

Key words: Superconducting tokamak, RTIB, Superconducting magnet, Helium, High voltage
