摘 要: 介绍了气体绝缘输电线(gas insulated transmission lines,GIL)的优势与发展历程,研究了三氟碘甲烷(CF3I)的电气绝缘性能,根据CF3I气体的饱和蒸汽压曲线和范德瓦尔斯方程,给出了CF3I与理想气体混合后的液化温度与气体混合比例及压强之间的关系曲线,提出采用新型环保气体——CF3I作为GIL中的绝缘介质。研究表明:采用CF3I的第三代GIL比第一代和第二代GIL更加环保,具有更好的综合性能。
关 键 词: 高电压绝缘技术;气体绝缘输电线;CF3I;环保

Abstract: The paper introduces the advantages and development of gas insulated transmission lines (GIL), also studies the electric insulation performance of CF3I. According to the saturated steam pressure curve and van der Waals equation of CF3I, the relationships between liquefaction temperature of the mixture of CF3I and ideal gases and gas mixture proportion and pressure are given. The new environmentally friendly gas CF3I is proposed to be insulating medium used in GIL. The results show that the third generation of GIL using CF3I which has better comprehensive performance is more environmentally friendly than the first and second generation of GIL.
Key words: high voltage insulation technology; gas insulated transmission lines; CF3I; environment protection
