在横向磁场作用下，观察了真空电弧形态的变化，分析了真空电弧的中频伏安特性。利用TMF接触模型计算了TMF和相移时间，发现高频磁场的大相移有利于残余等离子体的弥散过程。800 Hz时的弧速高于400 Hz时的弧速。可以推断，TMF将鼓励800赫兹的电弧运动。此外，电弧运动对电弧电压也有影响。由于弧柱长度的增加和弧速的提高，拉长的电弧会导致电弧电压的增加。具体地说，本文将真空电弧的伏安特性分为三个阶段。频率越高，电弧电压的初始上升率越大，被电弧伏安特性包围的面积越大。文中还给出了弧压与电流幅值和频率的关系。
In this study, the changes of a vacuum arc's appearance were observed and the volt-ampere characteristics of the vacuum arc at intermediate frequency were analyzed under a transverse magnetic field (TMF). The TMF and phase shift time were calculated by using the TMF contact model and the large phase shift of the magnetic field at a higher frequency was conductive to the dispersion process of residual plasma. The arc velocity was higher at 800 Hz than at 400 Hz. It can be inferred that TMF will encourage arc movement at 800 Hz. Moreover, the arc movement has an impact on the arc voltage. Because of the increasing length of the arc column with a high arc velocity, the elongated arc causes the arc voltage to increase. Specifically, the volt-ampere characteristics of the vacuum arc are divided into three stages in this paper. The higher the frequency, the greater the initial rate of rise in the arc voltage and the larger the area surrounded by arc volt-ampere characteristics. The correlations between the arc voltage and the amplitude and frequency of the current are also presented.
