本文叙述密封真空触发管的特性,讨论了它作为过压保护器件的应用中所遇到的困难。说明通过使用除过气的电极材料和在要求间隙击穿时通过触发,怎样来改进这些困难。讨论了几种触发方法,并说明几个把少量的电离的氢注射到间隙中去的实用的触发器件,最后使用氢化钛消气剂把氢回收掉,结果表明,用首先产生辉光放电,而后迅速转变为金属蒸汽电弧的方法,能在小于十分之一微秒的时间内实现间隙的击穿。叙述了金属蒸汽电弧的性能对真空触发管的特性的影响,叙述几个实用的并封离的真空触发管,这些管子用来承载微秒级的电容器放电电流,和半周的60周电力线的电流,工作电压范围从几百伏到100千伏。说明了真空间隙比充气间隙具有的优点,列举了一些过压保护和开关的应用。
This article describes the characteristics of a sealed vacuum trigger tube and discusses the difficulties it encountered as an overvoltage protection device. Explain how to improve these difficulties by using degassed electrode materials and triggering when a gap is required. Several triggering methods are discussed, and several practical trigger devices are shown that inject a small amount of ionized hydrogen into the gap. Finally, the titanium hydride getter is used to recover the hydrogen. The results show that glow discharge first occurs and then The rapid transition to metal vapor arcs enables gap breakdown in less than a tenth of a microsecond. The effect of metal vapor arc performance on the characteristics of the vacuum trigger tube is described. Several practical and sealed vacuum trigger tubes are described, which are used to carry the microsecond capacitor discharge current and the 60 week power line current Operating voltage range from a few hundred volts to 100 kV. Describes the vacuum gap than the advantages of the air gap, lists some of the over-voltage protection and switching applications.
