AI Technical Summary

Technical Problem

Traditional methods for assessing the aging performance of electrical equipment insulation materials under multiple influences require extensive experiments and make it difficult to accurately analyze the relative impact of each factor.

Method used

An orthogonal experimental design was adopted. By determining the factors affecting the aging performance and their levels, an experimental scheme was generated, breakdown strength data was obtained, significant impact values ​​were calculated, and factors below the preset significance level were identified as the selected factors affecting the aging performance.

Benefits of technology

It reduces the number of factor determination experiments, saves time and resources, and enables a comprehensive understanding of the interactions between factors and precise analysis of the significance of each factor.

Abstract

Disclosed in the present invention are an aging performance influencing factor determination method and apparatus for a solid insulating material, a terminal device, a storage medium and an aging performance evaluation method. The aging performance influencing factor determination method comprises: on the basis of the number of aging performance influencing factors to be selected of a solid insulating material and the number of corresponding factor levels, determining an orthogonal experimental solution; acquiring the breakdown strength of the insulating material under different factor levels of each of said aging performance influencing factors, the breakdown strength being obtained by means of the orthogonal experimental solution; on the basis of the breakdown strength, calculating the significant effect value of each of said aging performance influencing factors; and comparing the significant effect value of each of said aging performance influencing factors with a preset significance level, and determining, as a selected aging performance influencing factor, an influencing factor the corresponding significant effect value of which is lower than the preset significance level. The present invention can be used to effectively reduce the number of factor determination experiments, thereby saving time and resources.
