伪火花放电开关的陶瓷表面放电触发研究

 设计了伪火花开关的陶瓷材料表面放电触发器，该触发器体积小，结构简单，可焙烧。经大量实验表明，较传统的表面放电触发器可靠性提高，寿命延长，用它触发的伪火花开关（放电电压30~2kV）具有稳定的放电时延（50~340ns）和时延抖动（15~40ns）。由于触发电流大，因此可在极低的开关电压下触发开关，对耐受电压30kV的伪火花开关，其最低可触发开关电压可至600V。

Ceramic Surface Flashover Triggering of Pseudospark Switchs

In this paper, a new ceramic surface flashover trigger of pseudospark switch is presented for the first time. Experiments(>10 5)demonstrate that this trigger has long lifetime and the triggered pseudospark switche provides an excellent delay of 50～340ns and jitter of 15～40ns at the discharge voltage of 30～2kV. The emitted plasma electron density is high enough to trigger switches reliably at a low voltage of 600V.
