| 摘 要： | 本文用半椭球凸出物模型计算了在SF_6/N_2和SF_6/CO_2中电极表面粗糙度对耐电强度的影响。计算表明:在电场畸变严重时,两种混合气体的击穿强度均高于纯SF_6,且SF_6/CO_2优于SF_6/N_2。这一结论并为实验结果所证实。

Effect of Partial Field Distortion on Dielectric Strength of SF_6/N_2 And SF_6/CO_2 Gas Mixtures |
| |
| Abstract: | The effect of electrode surface roughness on breakdown in SF6/ N2 and SF6/CO2 was computed using a hemi-ellipsoidal protrution model. The computation shows that in the case of serious field distortion the breakdown strengths of both SFg gas mixtures are higher than that of pure SF6, and SF6/CO2 is superior to SF6/N2. This conclusion was verified by the experimental results. |
