  • Received Date: April 20, 2015
  • The static breakdown voltage of the switch is determined by the working gas pressure. Graphite electrodes will erode during the discharge operation of the system. The erosion of the electrodes causes rise of the space of them. We must make sure that the over-voltage rate is relatively stable when changing the inner gas pressure of the switch. When the over-voltage rate of the switch is low, the rate of unstable triggering and self-fire will decline. In this paper we compare the DC breakdown voltage of different switches under different gas pressures and test their triggering reliability. The range of working gas pressure in various stages can be determined by analyzing the experimental data. Based on the over-voltage rate which makes sure conduction of the switch, we finally get the gas pressure regulation method to ensure the operation stability.
