Abstract |
It is very desirable that a mixture gas possessing excellent insulation performance is suggested for insulation on increasing high voltage. This paper proposes a SF6 mixture gas based on the factors including dielectric strength, environmental impact and economic feasibility of manufacture for the insulation in eco-friendly power equipment. A suitable-SF6 content was determined to improve the dielectric strength in N2 and Dry Air. The examination results of the factors revealed that a SF6/Dry Air mixture gas possessing the SF6 content was more appropriate than a SF6/N2 mixture gas to the eco-friendly power equipment. In addition to the selection of the suitable SF6 mixture gas, insulation characteristics as a function of SF6 content were described from electron-detachment mechanism. |
