【摘要】 本文对带引燃极的S波段微波气体放电管进行击穿试验,以研究分析微波气体放电管的击穿特性。该实验过程中不改变该气体放电管结构参数和管内气体成分。设置引燃电压脉冲与输入微波脉冲同步,使得该放电管在微波脉内主动击穿。采集放电管击穿前后的泄露信号和反射信号的时域波形数据,对数据进行统计分析,研究击穿时刻以及击穿波形的变化规律。数据分析结果显示:该气体放电管脉内击穿过程存在预击穿过程。预击穿所需时间以及击穿时刻都具有离散性,并且都与输入功率和引燃极电压有关。当放电管结构和气体组分固定时,可通过调节输入微波功率和引燃电压来增强放电管的稳定性。更多还原

【Abstract】 In this paper, the breakdown test of a S-band microwave gas discharge tube with an ignitor was carried out to study and analyze the breakdown characteristics of the microwave gas discharge tubes. The structural parameters of the tube and the composition of the gas inside the tube were not changed during the experiment. The ignition voltage pulse was synchronized with the input microwave pulse, so that the tube broke down at a time point within the microwave pulse. The time-domain waveform data of the leakage and reflection signals before and after the breakdown were collected respectively. The data were statistically analyzed to focus on the breakdown time point and the change law of the breakdown waveform. The results indicate that the tube discharge process which broke down at a time point within a pulse contains a pre-breakdown process. The time required for the pre-breakdown process and the time point of breakdown of the tube are discrete and related to the input power.When the tube structure and gas composition are fixed, the input microwave power and ignition voltage can be adjusted to enhance the stability of the tube.更多还原
