摘要

由于SF

气体温室效应严重

因此亟需找到一种能够替代SF

气体的环保型绝缘气体。利用传统解析法

对不同气压下充有不同体积分数CF

I气体的CF

I-N

及CF

I-CO

混合气体绝缘的气体绝缘输电线路（GIL）的导体温度和外壳温度进行了计算

并与同等条件下采用SF

气体以及含20%体积分数SF

气体的SF

混合气体的情况进行了对比

分析了CF

I及其混合气体的散热性能。结果表明:同等条件下

I-N

混合气体的散热能力优于CF

I-CO

混合气体。而含30%

0%体积分数CF

I气体的混合气体的散热能力也优于已经广泛应用的SF

及20%SF

与80%N

的混合气体

最高可达到纯SF

气体的1.05倍以及20%SF

与80%N

混合气体的1.1倍。综合考虑绝缘特性、散热特性和液化温度等多方面因素

I气体体积分数为20%

0%的CF

I/N

混合气体可以在一定条件下用作GIL中的绝缘介质。

Abstract

Because of the severe greenhouse effect of SF

it is imperative to find an environmentally friendly gas substitute of SF

. Consequently

we calculated the conductor and enclosure temperatures of the gas insulated transmission line（GIL） insulated by CF

I-N

and CF

I-CO

gas mixtures with different CF

I ratios and pressures by traditional anal

ytical methods. By comparing with the results of SF

gas and SF

-N

gas mixture with 20% SF

under the same conditions

we discussed the heat dissipation potentials of CF

I and its mixtures.The results show that CF

I-N

gas mixture has a better cooling ability than CF

I-CO

. The cooling ability of gas mixtures containing 30%

0% CF

I gas can be better than that of SF

and 20%SF

-80%N

gas mixture

and it can each up to 1.1 times better than that of 20%SF

-80%N

gas mixture as well as 1.05 times better than that of pure SF

. After taking the insulation strength

heat dissipation characteristics and liquefaction temperature into consideration

I-N

mixtures with the CF

I ratio of 20%-30% can be used as the insulating medium in GIL under certain conditions.
