[12] reported the property and power frequency breakdown property of CF4, and they found that its dielectric strength is about 50% of SF6. HUANG [13] and XU et al [14] reported that arc extinction property of CF4 is about 50% of SF6. LI et al [15] previously reported the breakdown characteristics of CF4 and CF4/N2 hybrid gas in slightly non- uniform electric field under lighting impulse, which......
Improved Breakdown Strength in(Ba0.6Sr0.4)0.85Bi0.1TiO3 Ceramics with Addition of CaZrO3 for Energy Storage Application汪小红1,2,LI Zhenlin1,2,CHEN Fangyuan1,2,高俊雄1,2,Lü Wenzhong1,21. School of Optical... and dielectric breakdown strength improved obviously and reached 19.9 k V/mm at x=7.5. In virtue of low dielectric loss(tan d<0.001 5), moderate dielectric constant(er >1 500) and high breakdown......

; gas insulation 1 Introduction SF6 has excellent dielectric strength and interruption performance. For this reason, it is widely used in GIS, GIL, GIB. However SF6 is very sensitive to field utilization... of recent research, c-C4F8 and CF3I are possible substitute gas for SF6 at room temperature [3]. The dielectric strength in homogeneous field of these two gases is higher than that of SF6 [4], in which......
