| 摘 要： | 作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的GIS电极装置由固定导电微粒引发的击穿电压的影响,结果表明:SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大,而与波长的关系不大,当采用SF_6/空气混合气体时,则这种影响随SF_6含量增大而愈明显,并与电场不均匀程度有关。

Influence of Impulse Voltage Waveshape on particle Initiated Breakdown Voltages of GIS |
| |
| Abstract: | The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity |
