A transformer insulation aging analysis system, including a temperature measurement module, an insulating paper module, and a paper-taking module; the insulating paper module includes a copper conductor, insulating paper for laying, and an insulating paper group for testing; the copper conductor is covered with insulating paper, and the temperature measuring probe is located at Paving between the insulation paper and the insulating paper group for testing; the paper taking module includes an insulating rope and a cover plate, one end of the insulating rope is fixed on the side of the cover plate facing the box cover, and the insulating rope is used to put the insulating paper group for testing and the insulating paper for laying Fixed on copper conductor. On the one hand, the internal temperature of the transformer can be obtained through the temperature measuring probe and the transmission structure; A sufficient amount of insulating paper is extracted under the premise of safety. On this basis, the degree of insulation aging can be judged to determine whether the transformer has insulation aging defects. It has the advantages of being ready to use, economical and fast.
Description
technical field [0001] This application relates to the field of transformer insulation aging analysis, in particular to a transformer insulation aging analysis system. Background technique [0002] Transformer solid insulation is composed of fibrous substances, which generate CO and CO after aging 2 as well as furfural, so it is possible to measure CO and CO 2 As well as the content of furfural and the degree of polymerization of insulating paper to diagnose the defects of transformer insulation aging, and to judge the degree of insulation aging, the brief description is as follows. [0003] Method 1: Use liquid chromatography to measure the furfural content in the oil to judge the aging degree of the insulation. [0004] 1. Measure the concentration of furfural in oil (C 4 h 3 OCHO is furan formaldehyde), this is because the main chemical component in insulating paper is cellulose. Cellulose macromolecules are polymerized from D-glucose-based monomers. When the insula...
