摘要

为了寻找SF

的替代气体

文中对极不均匀电场中的10%

0%CF

I/CF

混合气体在不同极间距（5

5 mm）和不同气压（0.1

.3 MPa）下的工频击穿特性进行了实验研究。结果发现

I/CF

混合气体的工频击穿电压随着极间距的增大而近似线性增大

但是其随气压升高和CF

I体积分数的升高均表现出"驼峰"现象。与SF

相比

I/CF

混合气体的工频耐压水平在它的59%

20%之间。综合考虑

15%

0%CF

I/CF

混合气体可以作为SF

替代气体在合适的电气设备中使用。

Abstract

In order to look for SF

alternatives

this paper has experimentally researched AC breakdown characteris-tics of 10%

0%CF

I/CF

gas mixtures with different electrode gap distances（5

5 mm）and different gas pressures（0.1

.3 MPa）in condition of extremely non-uniform electric field. The results show that AC breakdown voltage ofCF

I/CF

gas mixtures nearly linearly increases as electrode gap distance increases

but

the voltage performs the well-known N shapeas the gas pressures and the ratio of CF

I increase. Compared with SF

power frequency withstandvoltage of CF

I/CF

gas mixtures is between 59%

20% of that of SF

. Taking every factor of account

15%

0% CF

I/CF

gas mixtures can be regarded as SF

alternatives to be applied in some proper electrical apparatus.
