Abstract

The arc-quenching capability of CO

is good

while its insulation performance is relatively low.Recently CO

attracts lots of attentions as a buf

fer gas for the potential substitutes for SF

. This paper aims to investigate the insulation performances of ten gas mixtures of CO

with SF

CF3 I

c-C

Air

C2H6

CH4 and CHF3by Boltzmann analysis. First

the electron energy distribution function

reduced ionization and attachment coefficients

reduced effective ionization coefficient

and critical reduced electric field strength of CO

/SF

mixture are calculated as an example. Then

the critical reduced electric field strength（E/N）crof ten CO

mixtures are given and compared. The study results indicate that

the values of（E/N）crof CO

/CF3 I and CO

/c-C

are clear higher than that of other gas mixtures in these ten gas mixtures

and the（E/N）crof CO

/CF3 I is higher than CO

/c-C

. When CO

concentration is below 80% and 50% respectively

the（E/N）crof CO

/CF3 I and CO

/c-C

are higher than that of CO

/SF

. When CO

concentration is below 25% and 15% respectively

the（E/N）cr of CO

/CF3 I and CO

/c-C

are even higher than that of pure SF
