Simulation method for thermal decomposition test of environment-friendly mixed insulating gas under micro-water condition

The invention relates to an environment-friendly mixed insulating gas thermal decomposition test simulation method under a micro-water condition in the technical field of electrical engineering insulation detection. The method comprises four steps of test condition setting, environment and experimental sample gas pretreatment, experimental process control and sampling and data processing. The test condition setting comprises the following steps: constructing a reaction system by utilizing a reaction force field module ReaxFF in analog mixed signal software AMS, and setting reaction volume, reaction temperature and reaction time parameters. The pretreatment of the environment and experiment sample gas comprises the steps of gas storage tank pretreatment, trace moisture injection, mixed gas pressure-controlled feeding into a tank and uniform mixing of the mixed gas. The experimental process control is temperature-control and humidity-control heating process control, the experimental temperature is stabilized at
