磁旋转弧等离子体中的弧电压突变现象

Phenomenon of the sudden change of arc voltage in the arcplasma rotated by magnetic field

利用光学成像系统观察到了磁旋转弧等离子体实验中的电弧电压突变现象,电弧电压突变的范围约在40～100V之间。实验结果表明,电弧电压的变化与电弧弧长的变化密切相关。

The phenomenon of the sudden change of arc voltage in the arc plasma rotated by a magnetic field is observed using an optical imaging system.The change in arc voltage of the phenomenon is roughly between 40 and 100 voltages.The results of the experiment show that the change in the arc voltage is closely related with the change in the arc length.
