的环保型气体，其绝缘特性一直受到广泛关注，其中微水和微氧环境下C

N气体的分解特性及其化学动力学过程是C

N气体绝缘特性研究的重要组成部分，而相关研究尤其是理论研究还相对较少。因此，文中以C

N为对象，通过量子化学计算方法，寻找并验证微水和微氧环境下的C

N气体可能反应路径，在此基础上计算了不同温度下反应路径对应的阿雷尼乌斯公式拟合参数，获得了给定温度范围内的反应速率系数。进一步地，利用计算得到的反应速率系数建立微水微氧环境下C

N气体化学反应动力学模型，研究了温度与微水微氧含量对C

N气体反应体系产物的影响。研究发现，微水环境下生成的稳定产物包括C

CONH

、（CF

）

CCNOH等，微氧环境下生成的稳定产物包括F

CO、（CF

）

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.
