摘要

研究了SF/sub 6//N/sub 2/和SF/sub 6//CO/sub 2/两种混合比例为50/50的气体混合物在高压电极表面有球形突起的平面平行间隙和中间介电空隙的气体浸透膜绝缘体系中的介电强度。在两种情况下，SF/sub 6//CO/sub 2/的介电强度均高于SF/sub 6//N/sub 2/，而在均匀或准均匀的大气压下，SF/sub 6//N/sub 2/优于SF/sub 6//CO/sub 2/。实验结果与利用这两种气体混合物的优值计算结果吻合得很好。

Comparison of SF/sub 6//N/sub 2/ and SF/sub 6//CO/sub 2/ gas mixtures based on the figure-of-merit concept

The dielectric strengths of SF/sub 6//N/sub 2/ and SF/sub 6//CO/sub 2/ gas mixtures, both with a mixing ratio of 50/50, were measured in a plane-parallel gap with a spherical protrusion on the high-voltage electrode surface, and in a gas-impregnated film insulation system with a mid-dielectric void. In both instances the dielectric strength of SF/sub 6//CO/sub 2/ was higher than that of SF/sub 6//N/sub 2/, in contrast to a uniform or quasi-uniform field gap at atmospheric pressure where SF/sub 6//N/sub 2/ is superior to SF/sub 6//CO/sub 2/. The experimental results were in good agreement with calculations using the figure-of-merit values for these two gas mixtures.<>
