| 摘 要： | 设计了一种具有环槽电极结构的新型伪火花开关，进行了空气介质下的耐压特性实验，并与传统的同轴多通道结构的伪火花开关耐压特性进行了对比。给出了伪火花开关工作的气压范围（1~100 Pa）和两种伪火花开关的最大耐压。实验结果显示，新型环槽结构伪火花开关最大耐压达到41 V，而传统同轴多通道开关的最大高耐压只有28.4 kV，新设计开关的最大耐压和耐压稳定性都明显高于同轴多通道开关。

| Abstract: | The measurement on the static breakdown voltages for two kinds of pseudospark switches with different electrode structures is presented.A newly designed pseudospark switch with two electrodes of 1 mm-wide annular slots was tested.Comparing the experimental results with that of a typical structure with eight equally-spaced 2 mm-diameter boreholes, it is found that the static breakdown voltage of the former is obvious higher than that of the latter under the same experimental conditions.A maximum hold-off voltage of 41 kV has been demonstrated for the annular-slot structure.Furthermore,the stability of the annular-slot structure is much better than the multihole one evidently. |
