Insulation characteristics of triple mixtures of c-C_4F_8/N_2/CO_2 under lightning impulse voltage
|
摘要
This paper has researched the insulation characteristics of 10% c-C_4F_8/N_2/CO_2 mixtures under lightning impulse voltage by experiment. It is shown that the positive and negative lightning impulse breakdown voltages of 10%c-C_4F_8/N_2/CO_2 gas mixtures rise linearly as the electrode gap distance and gas pressure increase and under the same conditions, the positive lightning impulse breakdown voltage of the gas mixtures is always higher than the negative lightning impulse breakdown voltage. As the gas mixtures have a little higher liquefied temperature than SF6 and the comprehensive GWP is about 5% of SF_6, and the positive and negative lightning impulse breakdown voltages can both reach 60% of SF6, 10%c-C_4F_8/N_2/CO_2 gas mixtures can be applied as insulation gas in electrical equipment such as C-GIS, GIT, GIL and so on.
