中央螺线管（CS）模块的JT-60SA电源含有多种频率成分，瞬态响应现象和谐振现象导致CS内电压不均匀。因此，导体之间可能会产生大于导体间绝缘体耐受电压的局部电压，从而损坏绝缘体。因此，瞬态响应现象和谐振现象的估计对于验证CS的电稳定性很重要。在本研究中，测量了JT-60SA CS模块的电源电压，并使用包括CS（四个模块）、电源和CS之间的电流引线以及CS周围的结构的分析模型来评估瞬态响应和谐振现象对CS导体之间的电压的影响。仿真结果表明，当对CS施加实际电源时，受瞬态响应和谐振现象影响的CS导体间最大电压低于CS导体间绝缘的耐压。我们的分析结果提供了基本数据，可用于估计 CS 中的电压分布，从而确保电气稳定性。
The JT-60SA power supply of the central solenoid (CS) module contains multiple frequency components, and the transient response phenomenon and the resonance phenomenon cause the voltage non-uniformity in the CS. There is thus a possibility that a local voltage between the conductors that is larger than the withstand voltage of the insulation between conductors will be occurred, and the insulation is damaged. Therefore, an estimation of the transient response phenomenon and the resonance phenomenon is important for verifying that the CS is electrically stable. In the present study, the power supply voltage of the JT-60SA CS module was measured, and the effect of the transient response and the resonance phenomenon on the voltage between CS conductors was evaluated using an analysis model that included CS (four modules), the current lead between the power supply and the CS, and the structures surrounding the CS. The simulation results show that when the actual power supply is applied to the CS, the maximum voltage between CS conductors affected by the transient response and the resonance phenomenon is lower than the withstand voltage of the insulation between CS conductors. The results of our analyses provide fundamental data that can be used to estimate the voltage distribution in the CS and thus ensure the electrical stability.
