摘要：

Because of the severe greenhouse effect of SF6, it is imperative to find an environmentally friendly gas substitute of SF6. Consequently, we calculated the conductor and enclosure temperatures of the gas insulated transmission line (GIL) insulated by CF3I-N2 and CF3I-CO2 gas mixtures with different CF3I ratios and pressures by traditional analytical methods. By comparing with the results of SF6 gas and SF6-N2 gas mixture with 20% SF6 under the same conditions, we discussed the heat dissipation potentials of CF3I and its mixtures. The results show that CF3I-N2 gas mixture has a better cooling ability than CF3I-CO2. The cooling ability of gas mixtures containing 30%~80% CF3I gas can be better than that of SF6 and 20%SF6-80%N2 gas mixture, and it can each up to 1.1 times better than that of 20%SF6-80%N2 gas mixture as well as 1.05 times better than that of pure SF6. After taking the insulation strength, heat dissipation characteristics and liquefaction temperature into consideration, CF3I-N2 mixtures with the CF3I ratio of 20%-30% can be used as the insulating medium in GIL under certain conditions. © 2018, High Voltage Engineering Editorial Department of CEPRI.
