Abstract

For studying the gas-solid compatibility between the environment-friendly insulating medium C

O andthe red copper material inside the insulating equipment

in this paper

the crystal surface of C

O and Cu（110）crystal plane is

analyzed from the micro level aspect and based on density functional theory（DFT）.Firstly

the activ-ity of C

O molecular functional group is analyzed by adopting the frontier molecular orbital theory

and the adsorp-tion configuration of C

O on Cu（110）crystal plane is established.Secondly

the adsorption energy and transfercharge generated by different adsorption configurations of C

O on Cu（110）crystal surface are calculated.Finally

the adsorption configuration of SF

on Cu（110）crystal surface is established and the difference of adsorption charac-teristics between C

O and SF

is analyzed.It is shown by the result that the activity of oxygen atoms in the molecu-lar structure of C

O is high

and chemical adsorption reactions could occur at different adsorption positions on thecrystal surface of Cu（110）

in which the adsorption energy and transfer charge generated on the top absorption config-uration is relatively bigger and absorption reaction is easily occurred.By comparing the adsorption characteristics ofC

O and SF

on Cu（110）crystal plane

it is shown that the adsorption capacity of C

O is weaker than that of SF

and the potential of C

O to replace SF

in insulating equipment is verified from the aspect of gas-solid compatibility.
