Abstract

The invention discloses a system and method for detecting thermal ageing degrees of insulating cardboards. The system comprises image acquisition equipment, image reception equipment and analysis andjudgement module, wherein the image reception equipment is connected with the image acquisition equipment; the analysis and judgement module is connected with the image reception equipment; and the analysis and judgement module is used for detecting fiber widths, hole areas and surface roughness of insulating cardboards so as to judge thermal ageing degrees and residual life of the insulating cardboards. By adoption of the system and method provided by the invention, the influences of subjective factors can be reduced and the detection precision can be improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment fault diagnosis, in particular to a detection system and method for thermal aging degree of insulating cardboard. Background technique [0002] The internal insulation of oil-immersed transformers is mainly oil-paper insulation, and its main insulation materials are insulating oil, insulating paper and cardboard. As an important part of transformer insulation, cardboard insulation determines the overall insulation of the transformer. Its role is prominent and significant. However, cardboard insulation is easily damaged by impact and difficult to recover, so the protection of cardboard insulation is particularly important. [0003] With the development of cellulose microscopic theory and the continuous improvement of the accuracy of observation equipment, domestic and foreign workers began to study the aging and breakdown process of insulating cardboard from a microscopic perspective, wh...
