| 摘 要： | 设计了Z箍缩实验装置中单路模块样机的低阻抗水介质三平板结构的传输线。根据三平板传输线的结构参数及相关计算公式，得到所设计的三平板传输线实际阻抗为4.08 Ω（设计阻抗为4.00 Ω）。在考虑传输线内板边缘与水箱耦合电容影响的条件下，采用有限元方法精确计算得到三平板传输线阻抗为3.77 Ω。根据实验得到的传输线入口、出口电压电流测量结果，计算得到三平板传输线的实际运行阻抗为3.83 Ω，与计算结果基本一致。另外，还对三平板传输线进行了静电场计算和分析，耐压实验表明，当三平板传输线出口电压达到3.1 MV时，未出现绝缘闪络,绝缘设计满足指标要求。 |

| Abstract: | A low impedance triplate transmission line, consisting of three parallel plate-electrodes, filled with de-ionized water, was designed for the Z-pinch Primary Test Stand (PTS) prototype. The determination of the triplate line’s parameters by its characteristic impedance cannot use the traditional bi-plate impedance formula, since the coupling-capacitance between the inner plate edge and water tank must be considered. The rated impedance of the triplate line was 4.00 Ω, and the designed impedance reached 4.08 Ω by the dimension of the triplate line without water tank. When considering capacitance coupling between triplate edge and water tank, the triplate line’s impedance was 3.77 Ω by precise FEM calculation. While, the actual operation impedance was 3.83 Ω according to measured volt |
