Description

technical field

[0001] The invention relates to the field of transformer analysis, and more specifically, relates to a data mining system for transformers. Background technique

[0002] The main transformer is one of the most important power equipment, which is directly related to the normal conversion and transmission of electric energy. Therefore, effective condition monitoring of the main transformer can greatly improve the healthy operation level of the power grid. The structure of the main transformer is also the most complicated power equipment, and its components include the body (iron core, winding, insulation, lead wire), transformer oil, oil tank and cooling device, voltage regulating device, protection device (moisture absorber, safety airway, Gas relay, oil conservator and temperature measuring device, etc.) and outlet bushing, etc. Defects in each part of the main transformer may cause problems during operation and cause serious consequences, so effective monit...
