영문 초록

With the improvement of industrial society, the high quality electrical energy, simplification of operation and maintenance, ensuring reliability and safety are being required. This paper reviews a basic data of the surface discharge characteristics for teflon resin in not only pure N2, N2:O2 mixture gas and Dry-Air as being focused on environmentally friendly insulating Gas also SF6. An experimental set-up of electrodes are utilized as a type of knife-to-knife. With the changing distance of electrodes and pressure, we can find surface discharge voltages and surface dielectric strengths respectively. Surface discharge Voltages of N2:O2=80:20 mixture gas are more higher than the N2:O2 Mixture gases. we verify replaceability of Imitation-Air according to gas pressure and gap as well as gas pressure to replace 1[atm] SF6 gas when eco-friendly Imitation-Air is applied to insulation design of various HV power equipment instead of SF6 gas. As a result, it is verified that the gas pressure of Imitation-Air which correspond to the breakdown voltage of SF6 1[atm] is about 3[atm] at distribution class.
