雷电冲击下尖板间隙中 SF_6 放电过程的计算

Calculation of Discharge Process of SF 6 in a Point/plane Gap under Lightning Impuls

用光电倍增管研究了雷电冲击下尖板间隙中ＳＦ６的放电发展过程。根据实验结果，改进了现有的ＳＦ６放电模型，并据此设计了能够计算驼峰区从起晕到最后击穿的放电发展的程序。

The lightning impulse discharge process of SF 6in a point/plane gap is investigated using a photomultiplier tube. Based on the experimental results, the existing discharge model is modified, and a computer program is developed to calculate the discharge process from corona onset to final breakdown.
