Abstract

The invention discloses a casing defect detection method, a storage medium and a processor. The casing defect detection method comprises the steps of obtaining first predetermined parameters of a casing in a transformer, wherein the first predetermined parameters at least comprise a dielectric loss value of the casing, an effective value of the resistive current of the casing and a contact resistance value of a connector lug inside the casing; and detecting whether the casing is a defective casing or not through comparing the first predetermined parameters of the casing with second predetermined parameters, wherein the second predetermined parameters are used for reflecting a casing with defects, and the defects at least comprise that the casing is affected with damp and a lead inside thecasing is poor in contact. The casing defect detection method solves a technical problem that defects of a casing of the transformer cannot be effectively detected in the prior art.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a detection method, a storage medium, and a processor for casing defects. Background technique [0002] In the field of electric power, the damp of transformer bushing insulating oil is mainly caused by the failure of the rubber pad seal, the poor seal of the top of the oil-paper capacitive bushing, and lack of oil. The main hazards when the bushing insulating oil is damp are: not only the insulation level is reduced after being damp, but also the aging speed of the insulating medium will be accelerated. In addition, when the bushing insulating oil is damp, the leakage current will increase, and the interface of the interlayer medium will be extremely damaged. Intensification; the increase in the loss of the insulating medium will cause the internal heating of the insulation, and the temperature will rise further. If this situation continues in a cycle, it will cause the...
