Investigation on Diffusion Mechanisms of Methanol in Paper/Oil Insulation Based on Molecular Dynamics Simulation

Methanol is regarded as an available indicator to analyze the aging condition of cellulose insulation. However, diffusion mechanism methanol molecules in paper-oil insulation system still unclear, since it cannot be explored by using only experiments. Given this issue, molecular dynamics simulations were performed investigate molecules. In current work, mean square displacement during process was calculated and analyzed, well its trajectory tracking. Then, research on interaction energies hydrogen bonds paper/oil conducted. Finally, effect temperature also studied. Findings revealed that faster than insulating oil, besides, presence affects rate oil. Thus, present findings could support investigation mechanisms molecules, which evaluation promoted.
