Triggered spark-gap switch is a popular discharge switch for pulse power systems. Previous studies have focused on planarizing this switch using thin film techniques in order to meet the requirements of compact size in the systems. Such switches are one-shot due to electrodes being too thin to sufficiently resist spark-erosion. Additionally, these switches did not employ any structures in securing internal gas composition, resulting in inconsistent performance under harsh atmospheres. In this work, a novel planar triggered spark-gap switch (PTS) with a hermetically sealed cavity was batched-prepared with printed circuit board (PCB) technology, to achieve reusability with low cost. The proposed PTS was inspected by micro-computed tomography to ensure PCB techniques meet the requirements of machining precision. The results from electrical experiments demonstrated that PCB PTS were consistent and reusable with lifespan over 20 times. The calculated switch voltage and circuit current were consistent with those derived from real-world measurements. Finally, PCB PTS was used to introduce hexanitrostilbene (HNS) pellets in a pulse power system to verify its performance.

触发式火花隙开关是脉冲电源系统常用的放电开关。以前的研究集中在使用薄膜技术对这种开关进行平面化，以满足系统中紧凑尺寸的要求。由于电极太薄而无法充分抵抗火花腐蚀，因此此类开关是一次性的。此外，这些开关没有采用任何结构来确保内部气体成分，导致在恶劣环境下性能不一致。在这项工作中，采用印刷电路板 (PCB) 技术批量制备了一种具有密封腔的新型平面触发火花隙开关 (PTS)，以实现低成本的可重复使用性。拟议的 PTS 是通过微计算机断层扫描检查，以确保 PCB 技术满足加工精度的要求。电气实验结果表明，PCB PTS 具有一致性和可重复使用性，使用寿命超过 20 次。计算出的开关电压和电路电流与根据实际测量得出的结果一致。最后，使用 PCB PTS 在脉冲电源系统中引入六硝基芪 (HNS) 颗粒以验证其性能。
