In accordance with the technological difficulties encountered in the process of insulation supervision based on the Dissolved Gases Analysis,several kinds of model and method are presented to improve the reliability and precision of fault diagnosis of the power transformer. Main research content includes:By deeply studying the common transformer faults diagnosing methods,such as three-ratio methods and improved electrical committee agreements,several shortcomings such as uncertainness judgment when the fault reasons,phenomenon and principles come out together while can not consistent to each other etc. For this reason,the old methods can not fully meet the need to engineering practical application.Considering fuzzy relationship matrix can fully represents the causality between fault symptoms and fault types,when diagnosing complex equipments with multiple symptoms and fault causes such as power transformer,a synthetic fuzzy diagnosing model is firstly proposed to diagnose transformers insulation faults based on DGA in this paper. Meanwhile,by further study the character of fuzzy factors,aimed at correcting the defects in classifying fuzzy sets of common fuzzy judgment,a method are put forward by unifying fuzzy synthetic diagnosis and fuzzy principle reasoning.

That in female was Uu, Ng, Mh, eumycetes, Trichomonas and Ct in descending sequence. Constituent ratio of eumycetes and Trichomonas in female was higher than that in male (x^2=50.0l, P.001), while that of NG was higher in male (x^2=13.86, P.01), and mixed infection rate was higher in female (x^2=6.98, P.05). Conclusion Ng and Uu were the common pathogens of genitourinary infection in male, while eumycetes and Uu were the common pathogens in female.
