In accordance with the technological difficulties encountered in the process of insulation supervision based on the dissolved gases analysis ( dga ), 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 transformer ' s insulation faults based on dga in this paper
本文針對應用油中溶解氣體分析方法進行變壓器絕緣監督時所遇到的主要技術難點，提出了提高變壓器故障診斷的準確性、可靠性的幾種模診斷方法，主要研究內容有：通過對判斷變壓器故障常用的三比值法和改良電協研法的深入分析，其診斷準確率較高，但對故障原因、故障現象和故障機理間同時存在不確定性和模糊性的變壓器等電氣設備的故障診斷，難于滿足工程應用的需要；在處理變壓器等結構復雜設備的多癥狀、多原因故障診斷時，模糊關系矩陣可以全面反映這種癥狀與故障類型間的因果關系，進而提出了變壓器故障診斷的模糊綜合診斷模型；同時作者還深入分析了模糊運算元的特性；針對常用的模糊評判結果的模糊集的集化方法的不足性，提出了將模糊綜合診斷與模糊規則推理結合起來進行故障診斷的方法，能達到較好的效果。 -
On the base of analyzing the development of control system for synthetic rubber press internationally, and combining the development status quo of applied research of reliability engineering of hydraulic systems, to overcome the design limitations of traditional control system for synthetic rubber press and such faults as high energy - consume, long process period and low reliability in the pressing process of synthetic rubber in the post - treatment product line, brand - new design and reliability research are to be carried out for the new control system
