摘要
讨论了被外磁场驱动的滑移弧。磁驱动滑移弧的放电频率随磁感应强度增大而增大,测得的放电频率约在46～517Hz之间;当外加磁感应强度为0.4829T时,用光电倍增管测得滑移弧运动的平均速度为26.4m·s-1;从磁驱动滑移弧的放电电压曲线可以看出,电弧运行在电极平行段时,电压增加缓慢,当电弧运动到电极顶部时,电压上升较快,从1778V迅速增加到约4000V。
A gliding arc driven by the outside magnetic field is discussed. The discharge frequency of the gliding arc increases with the magnetic inductance, and the frequency measured is from 46 to 517 Hz. The mean velocity of the gliding arc measured with a photo-multiplier is about 26.4 m·s^(-1) when the magnetic inductance is 0.4829 T. It can be seen from the voltage curve of arc discharge that the voltage increases slowly when the arc moves on the parallel part of electrodes, and that the voltage increases rapidly from 1778V to 4000V when the arc is on the top of electrodes.
