CFO、CO等；随着温度的增加，相关反应速度加快，生成稳定产物的时间缩短；随着微水微氧含量的增加，稳定产物的摩尔分数也对应成比例增加。

Abstract

an environmentally friendly gas with potential to replace SF

has received widespread attention regarding its insulation charcateristics. Among these characteristics

the decomposition properties of C

N under micro-water

and micro-oxygen cndition

as well the associated chemical kinetic process

constitute an important part of the research on C

N gas insulation performance. However

relevant studies

particularly theoretical investigations

remain relatively limited. Therefore

in this paper the C

N is taken as the object of discussion

the possible reaction path of C

N gas in micro-water and micro-oxygen environment is searched and verified through quantum chemistry calculation method. On this basis

the fitting parameters of Arrhenius formula corresponding to the reaction path at different temperatures are calculated

and the reaction rate coefficient within the given temperature range is obtained. Furthermore

the kinetic model of chemical reaction of C

N gas in micro-water and microoxygen environment is established by using the calculated reaction rate coefficient

and the influence of temperature and micro-water as well as micro-oxygen content on the products of C

N gas reaction system is studied. It is found by the study that the stable products generated in the micro-water environment includeC

CONH

(CF

)

CCNOHand those generated in the micro-oxygen environment includeF

(CF

)

CFO

COetc. With the increase of temperature

the reaction rate is accelerated and the time of stable product formation is shortened. With the increase of the content of micro-water and micro-oxygen

the mole fraction of the generated stable product also increases proportionally.
