摘要: 实验研究了氢闸流管的工作特性以及均压处理的优化效果。实验发现加热电压对氢闸流管的工作特性影响较大，在不出现自放电的前提下，使用更高的加热电压能够获得更好的导通性能。触发脉冲的差异以及不同的阳极电压对氢闸流管的导通性能基本无影响。采用电阻对氢闸流管进行均压，能够使其电压分布更加均匀，并且对自放电现象有一些改善。该研究为氢闸流管的使用提供了参考。Abstract: The working characteristics of the hydrogen thyratron and the optimization effect of the potential equalization treatment are investigated experimentally. The experiments show that the heating voltage has great influence on the working characteristics of hydrogen thyratron, on the premise of no self-discharge phenomenon, using higher heating voltage can obtain better conduction performance. The differences of trigger pulses and anode voltages have little effect on the conduction performance of hydrogen thyratron. Using resistors to equalize the voltage of hydrogen thyratron can make the voltage distribution more uniform and alleviate the phenomenon of self-discharge. The research provides reference and guidance for the use of hydrogen thyratron.
