摘要

The study of thermal aging of the components of the paper-impregnated insulation of power transformers was carried out. Electrical and mechanical characteristics of special produced paper with the addition of microcrystalline cellulose and bacterial cellulose were investigated. The maximum mechanical strength of various types of insulating paper in the process of thermal aging was measured. The grades of the paper with the largest sorption capacity, slows the aging process, were defined. The possibility of increasing heat resistance of transformer paper by modification of cellulose structure by biopolymers is shown.
