摘要

研究了横向磁场对真空中非均匀场隙电强度的影响。测量是在电压范围为1.0至5.0 mm的间隙下进行的。结果表明，大于0.1 T的横向磁场会使真空绝缘的电强度增大，且随磁场强度的增大而增大。观察到击穿强度提高了50%。针面电极正排列时，击穿电压增幅最大。针-针排列的增加量较小，负针-平面电极排列的增加量最小。

Electric strength of point-point and point-plane gaps in vacuum in the presence of transverse magnetic field

Investigations were carried out to determine the increase in the electric strength of nonuniform field gaps in vacuum caused by transverse magnetic field. The measurements were under voltages with gaps ranging from 1.0 to 5.0 mm. The results show that a transverse magnetic field in excess of 0.1 T causes an increase in the electric strength of vacuum insulation, with the effect increasing with the magnitude of the magnetic field. Increases in the breakdown strength of up to 50% were observed. The largest increase of breakdown voltage was noted for a positive needle-plane electrode arrangement. The amount of increase was less for a needle-needle arrangement, and least for a negative needle-plane electrode arrangement.<>
