摘要

分析了电压击穿延迟时间与大电流中断前间隔时间的关系。当间隔>1 ms时，间隙的行为与冷电极相对应。针对这种情况，在单独的实验中，研究了延迟时间对各参数的依赖关系。在恒电压条件下，随着间隙距离的增大，间隙值急剧增大。由此得出结论，场发射而不是团块过程是导致后期击穿的原因。>

Vacuum breakdown with microsecond delay time (interrupters)

The delay time of voltage breakdown has been analyzed as a function of the time interval to preceding interruption of high currents. With intervals >1 ms the behavior of the gap corresponded to cold electrodes. For this case, in a separate experiment, the dependence of the delay time on various parameters has been studied. At constant voltage a steep increased with the gap distance was found. This leads to the conclusion that field emission rather than a clump process is responsible for late breakdowns. >
