摘要：
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 voltage and current waveform, showing good agreement with the calculated results. The insulation of the triplate line was also considered. The rated working voltage of the triplate line was 3 MV, and there was no flashover when the voltage of output end reached 3.1 MV in experiment, indicating that the triplate line's insulation design was reliable.
