Abstract

High-pressure gas switches enjoy widespread use in the scientific and commercial communities because of their ability to operate over a wide range of voltages and currents. However, a simultaneous requirement of continuous operation at high average power and high repetition rate has quite often limited their use. Improvement in the rep-rate capability of high pressure gas switches has been extensively investigated at the Dahlgren Laboratory of the Naval Surface Warfare Center (NSWC). Past work has demonstrated burstmode pulse repetition frequencies to 10 kHz, at voltages up to 500 kV or currents to 170 kA, by operating various highpressure hydrogen switches at approximately 50% of their self-break voltages. This paper describes recent work demonstrating continuous operation of one of these switches. Repetition rates up to 1.7 kHz at an average power of 16.5 kW and an operating voltage of 40 kV for >70 seconds are presented. The results for repetition rates from 670 Hz to 1.7 kHz show that the recovery curve obtained for burst-mode operation is reasonably predictive for continuous operation. Variation in the breakdown voltage during continuous operation is shown to be < 3 percent. The operating voltage, frequency and average power were limited by the experimental apparatus.

高平均功率氢火花隙实验

高压气体开关在科学和商业领域享有广泛的应用，因为它们能够在很宽的电压和电流范围内工作。然而，同时要求在高平均功率和高重复频率下连续运行，往往限制了它们的使用。海军水面作战中心(NSWC)的Dahlgren实验室已经对高压气体开关的重复率能力进行了广泛的研究。过去的工作已经证明，通过在大约50%的自断电压下操作各种高压氢开关，在高达500千伏或170千卡的电流下，爆发模式脉冲重复频率达到10千赫。本文描述了最近的工作，演示了其中一个开关的连续操作。在16.5 kW的平均功率和40 kV的工作电压下，重复频率高达1.7 kHz，持续时间为60 ~ 70秒。在670hz ~ 1.7 kHz的重复频率范围内，实验结果表明，突发模式下的恢复曲线对连续工作具有较好的预测效果。在连续工作期间，击穿电压的变化显示为< 3%。工作电压、频率和平均功率受实验装置的限制。
