Transformer dry casing defect simulation and performance state monitoring system and method

Abstract

The invention discloses a transformer dry casing defect simulation and performance state monitoring system and method. Two ends of a conducting rod are connected with a transparent organic glass cavity through sealing rings, two ends, extending out of the transparent organic glass cavity, of the conducting rod are respectively connected with a first grading ring and a second grading ring, one endof the conducting rod is connected to a voltage source output end of the voltage source module through the first grading ring and a corresponding connector lug, a test signal interface of a dielectricresponse test module is connected with one end of a conducting rod through the first grading ring and the corresponding connector lug, a monitoring signal interface of a discharge characteristic monitoring module is connected with the other end of the conducting rod through a second grading ring and a corresponding connector lug, and the two ends of the conducting rod are connected to two poles of a current source module through the first grading ring and the corresponding connector lug, and the second grading ring and the corresponding connector lug respectively; according to the invention,accurate detection and simulation of casing defects can be realized.

Description

technical field [0001] The invention relates to the technical field of detection and monitoring of insulation performance status of electric equipment, in particular to a system and method for simulating defects of transformer dry-type bushings and monitoring performance status. Background technique [0002] Transformer bushing is a key component of a power transformer, and its reliable operation plays an important role in the safety and stability of the transformer. Therefore, in order to detect transformer bushing defects in time, it is necessary to study and analyze the characteristics and changing rules of different defects, as well as the detection or monitoring methods of bushing performance status. This helps to effectively grasp the defect characteristics of the defective casing, realize accurate detection or monitoring of the casing defect, and ensure the safe and stable operation of the casing. [0003] High voltage bushing faults account for about 30% of the tota...
