Abstract

The invention relates to a method for determining the type of a solid insulating material of a transformer. The method comprises the following steps: carrying out principal component analysis on nearinfrared spectrum data of a to-be-detected transformer oil paper insulating material; generating a clustering result profile, comparing the clustering result distribution diagram of the to-be-detectedmaterial with the clustering result distribution diagram of the plurality of transformer solid insulating material samples so as to determining whether the to-be-detected material belongs to a plurality of transformer solid insulation material samples or not, further determining the material type of the to-be-detected material. The determination process is rapid and accurate, the transformer solid insulation material is not damaged in a near infrared spectrum data analysis mode, the cost is saved, and the operation is simple.

Description

technical field [0001] The present application relates to the technical field of evaluating the aging state of insulating materials, in particular to a method for determining the type of solid insulating materials of transformers. Background technique [0002] The insulation structure of high-voltage and large-capacity power transformers is mainly composed of fiber materials such as insulating paper and mineral insulating oil. The insulating oil can be purified, regenerated or replaced in time according to the aging situation, while solid insulating materials such as insulating paper Cannot be replaced directly. Therefore, the aging state of the solid insulating material greatly affects the operating life of the transformer, and it is necessary to detect the aging state of the insulating paper of the oil-immersed transformer. [0003] The traditional method for detecting the aging state of insulating oil paper generally evaluates the aging state by measuring the physical an...
