Abstract

The invention relates to the technical field of insulation performance testing, in particular to a method for predicting the insulation strength of ultrahigh-pressure helium and electronic equipment, and the method comprises the steps: building a plasma fluid simulation model; a multi-particle multi-reaction system is considered; acquiring migration rates and diffusion coefficients of all particles, and inputting the migration rates and the diffusion coefficients into the simulation model; setting environmental parameters in the simulation model according to the actual working condition of helium; setting potential boundary conditions of the simulation model; performing simulation model calculation by using a numerical calculation method, and judging whether breakdown occurs or not; if not, using a dichotomy voltage parameter to scan and correct potential boundary conditions, and performing simulation model calculation again; if yes, the critical breakdown voltage of helium is obtained. Through the prediction method and the electronic equipment, the helium breakdown voltage under different air pressures and different gaps can be predicted, and the problem that a prediction result is far away from an actual value in the prior art can be solved.
