摘　　要：利用光电倍增管及分幅式变象管高速相机对放电所产生的光信号进行了检测。实验证明 ,光电检测是研究快速振荡冲击 (FOI)作用下 SF6 气体放电过程的有效手段。由检测结果可看出 ,SF6 气体间隙在 FOI下的放电特征与标准雷电波 (L I)下的放电特征是不同的 ,负极性Pre\|discharge and discharge characteristics of SF\-6 gas in a point/plane gap are investigated by using a photomultiplier tube and a high speed framing camera under negative fast oscillating impulse voltages. The results show that the photoelectric measurement is a very efficient method to study the pre\|discharge and discharge characteristics, and the discharge behavior under fast oscillating impulse voltages (FOI) is different from that under the lightning impulse voltages (LI). Based on photoelectric studies, it can also be seen that breakdown of SF\-6 in a point/plane gap under FOI can be explained by the stem leader mechanism.
