摘要
单匝线圈（STC）是一种以 100-300 T 超高磁场为目标的破坏性脉冲磁体。提出了一个考虑电磁扩散和导体变形耦合的瞬态放电电路模型，并研究了线圈的瞬态阻抗特性。结果表明，由于电磁扩散和温度上升，线圈电阻分别先减小后增大，而由于导体向外运动，线圈电感始终增大。通过比较，仿真结果与实验数据一致，验证了模型的正确性。
The transient discharge circuit analysis of single-turn coil
Single-turn coil (STC) is a destructive pulse magnet aiming at a 100–300 T ultra-high magnetic field. A transient discharge circuit model considering the coupling of electromagnetic diffusion and conductor deformation is proposed, and the transient coil impedance characteristics are investigated. The results show that the coil resistance first decreases and then increases due to electromagnetic diffusion and temperature rise, respectively, while the coil inductance always increases because of the conductor’s outward motion. By comparison, the simulation results are consistent with the experimental data, and the correctness of the model is validated.
