บทคัดย่อ

At present, equipments in Gas Insulated Substation(GIS) such as circuit breaker, ground switch, busbar and transformer use SF6 as its insulation because of its better electrical withstand, less area for installation and arc quenching for circuit breaker. However, SF6 has high cost. Furthermore, it causes green house effect and poisonous environment. In this research, the voltage withstand of Ar, He, O2, CO 2, Air, and N2 was studied to compare with that of SF 6. The voltage withstand of each gas under 50 Hz AC voltage was studied using a chamber designed following ASTM D 2477-96 which consists of rod-plane and sphere-plane gap made of stainless steel. Gap distances in this experiment were 5, 10, 15 and 20 mm while the gas pressures were varied to 1, 2 and 3 bars. The results show that He has the lowest voltage withstand compared to other gases at the same gap distance and pressure. ฉ 2011 The Institute of Electrical Engineers, Japan.
