Embodiment Construction
[0051] Shown with reference to accompanying drawing, the present invention discloses a kind of method for evaluating the health index of transformer real-time state, and it comprises the following steps:
[0052] (1) Formulate the transformer health index to characterize the ability of the transformer to maintain its specific performance. According to the characteristics of the transformer, select six types of core dynamic parameters that can characterize the state of the transformer: transformer load, oil chromatography, partial discharge, infrared detection, iron core ground current and transformer vibration;
[0053] (2) Determine the degree of deterioration of each type of core dynamic parameter and the corresponding deduction value according to the set evaluation guidelines, and determine the weight coefficient of each type of core dynamic parameter to form a state evaluation system;
[0054] In this step, mathematical methods are used to calculate the weights reflecting ...
