Comprehensive Variable Weight Quality Evaluation of Oil Immersed Transformers

The author discusses and analyzes a quality assessment method specifically for oil immersed transformers in this article. The method used is actually based on the Analytic Hierarchy Process with comprehensive variable weights, as well as the quality assessment method for oil immersed transformers involving correlation coefficients. We conducted experiments on oil immersed transformers using Analytic Hierarchy Process (AHnducted quantitative and qualitative analysis on the data collected after the eP) and inverse entropy weight method, and coxperiment and the detection results in actual work. We combined the correlation coefficients of the instruments and equipment to derive various evaluation indicators for oil immersed transformers, sorted them according to their importance, and found their internal important relationships. Finally, based on fuzzy evaluation, we proposed a quality evaluation method for oil immersed transformers based on comprehensive variable weight. This method is very feasible and can effectively reflect the interrelationships between various indicators in oil immersed transformers and distinguish which ones are important. In practical work, it can be applied to the quality evaluation of oil immersed distribution transformers to improve work efficiency.
