| 摘 要： | 提出了一种多棒极型真空触发开关（TVS），利用3对棒形电极的特殊结构来增大主触头间的燃弧面积，从而有效地提高TVS通流能力。结合真空电弧电压实验，阐述了多棒极型TVS在不同的大电流等级下的电弧发展变化过程。电弧电压的变化表现了多棒极型TVS中多通道并联燃弧及其在各通道之间的电弧转移过程，从而使得真空电弧维持在扩散态。由此开发的TVS样品实现了225 kA的峰值电流，单次转移电荷量45 C。

| Abstract: | A triggered vacuum switch (TVS) with multi-rod electrode is proposed. The switch adopts three pairs of rod electrodes to enhance the arcing area of main electrode, leading to the promotion of current carrying ability. The arc development of the switch is discussed under different high currents. The parallel arcing and arc transfer process in the multiple channels are discussed according to the change of arc voltage. The arc transfer process helps to keep the vacuum arc in diffusion mode. In experiments, the TVS sample carried a peak current of 225 kA and realized charge transfer of 45 C in one pulse. |
