At present, the most widely used power transformers are oil-immersed transformers and dry-type resin transformers. The insulation of power transformers is the insulation system composed of transformer insulation. It is the basic condition for the normal operation and operation of the transformer. The service life of the transformer is Insulation material (ie oil paper or resin, etc.) determined by the life.

Practice has proved that most of the transformer damage and failure are caused by damage to the insulation system. According to statistics, due to various types of insulation failure occurred in the accident accounted for more than 85% of all transformer accidents. For the normal operation and attention to the maintenance of the management of the transformer, the insulating material has a very long service life. Therefore, the protection of the normal operation of the transformer and strengthen the reasonable maintenance of the insulation system, to a large extent to ensure that the transformer has a relatively long service life, and preventive and predictive maintenance is to improve the life of the transformer and improve the reliability of power supply key The

Oil-immersed transformers, the main insulating material is insulating oil and solid insulation materials, paperboard and wood blocks, etc. c so-called transformer insulation of the aging, that is, these materials affected by environmental factors decomposition, reduce or lose the insulation strength.

Solid paper insulation failure Solid paper insulation is one of the main parts of oil-immersed transformer insulation, including: insulating paper, insulation board, insulation pad, insulation roll, insulation banding, etc. The main component is cellulose, chemical expression (C6H10O6 ) N, where n is the degree of polymerization. In general, the degree of polymerization of new paper is about 1300, and when it reaches about 250, the mechanical strength has been reduced by more than half, and the degree of polymerization at the end of life is 150 to 200. After the aging of the insulating paper, the degree of polymerization and tensile strength will be gradually reduced, and generate water, CO, CO2, followed by furfural (furan formaldehyde). Most of these aging products are harmful to electrical equipment, which will reduce the breakdown voltage and volume resistivity of the insulating paper, increase the dielectric loss, decrease the tensile strength, and corrode the metal material in the equipment. Solid insulation has irreversible aging properties, its mechanical and electrical strength of the aging reduction can not be restored. The life of the transformer depends mainly on the life of the insulating material, so the oil-immersed transformer solid insulation material should have both good electrical insulation properties and mechanical properties, and after years of operation, its performance is slow, that is, aging characteristics.

1, the performance of paper fiber material. Insulating paper fiber material is the most important insulating component material in oil-immersed transformers. The paper fiber is the basic solid tissue component of the plant. The atoms of the constituent material molecules have positively charged nuclei and negatively charged electrons running around the nucleus. Conductor is different from the insulating material in almost no free electrons, insulators in the very small conductance mainly from the ion conductivity. The cellulose is composed of carbon, hydrogen and oxygen, so that there is a potential for the formation of water due to the presence of hydroxide in the molecular structure of the cellulose, so that the paper fibers have water-containing properties. In addition, these hydrogen atoms can be considered to be surrounded by various polar molecules (such as acids and water), which are combined with hydrogen bonds, making the fibers vulnerable to damage: the fibers often contain a certain proportion (about 7% ), These impurities include a certain amount of water, because the fiber was colloidal nature, so that the water can not be completely removed. This also affects the performance of paper fiber
