Abstract

The invention discloses a method and a system for simulating the influence of oxygen and moisture on C5F10O gas decomposition behavior characteristics, and the method is characterized in that the method comprises the following steps: step 1, designing to-be-decomposed simulation gas, and setting chemical reaction simulation conditions of the to-be-decomposed simulation gas; step 2, carrying out at least one time of molecular reaction kinetic simulation on the chemical reaction to obtain a decomposition product change trend in the chemical reaction simulation process; and step 3, based on the variation trend of the decomposer, obtaining a transition state and an energy barrier of the decomposer in the chemical reaction simulation process by using a density functional algorithm. Influence of oxygen and moisture on the decomposition behavior characteristics of the C5F10O gas can be quickly and accurately analyzed, the simulation cost is low, the result is accurate, and the maintenance and replacement of various high-voltage equipment or electronic equipment filled with the C5F10O gas can be effectively guided.

Description

technical field [0001] The invention relates to a computer simulation method, more specifically, to a simulation method and system for the influence of oxygen and moisture on the decomposition behavior characteristics of C5F10O gas. Background technique [0002] Currently, sulfur hexafluoride (SF 6 ) as a traditional insulating gas is widely used in various fields such as electrical equipment, electronics, and metallurgy. However, since SF 6 With high greenhouse effect and warming index, find a substitute for SF 6 A new type of environmentally friendly insulating gas has attracted widespread attention. Perfluoropentanone (perfluoron-propyl vinyl ether, C 5 f 10 O) gas not only has a lower greenhouse effect potential value, but also has the same 6 The insulation performance is comparable to that of gas, so it is considered to be the best insulating gas of the new generation. [0003] In prior art, C 5 f 10 Under the action of high temperature and strong electric fiel...
