Aging of insulating materials
Insulating materials will undergo physical phenomena such as polarization, conductance, medium heating, and breakdown under the action of electric field. While being subjected to the electric field, they will also be affected by many factors such as mechanical and chemical factors, and aging will occur in long-term work. Therefore, many failures of electrical products often occur in the insulating portion.
● Electrical aging. More common in high-voltage electrical appliances, the main reason is that the insulation material is partially discharged under the action of high pressure.
● Heat aging. More common in low-voltage electrical appliances, the mechanism is under the action of temperature. The internal components of the insulating material are oxidized, cracked, and deteriorated, and the water is hydrolyzed to gradually lose the insulating properties.
● The environment is aging. Also known as atmospheric aging, it is a polluted chemical aging caused by ultraviolet light, ozone, salt spray, acid and alkali. among them. Ultraviolet light is the main factor. Ozone is produced by corona or partial discharge of electrical equipment. The aging of the dielectric refers to a phenomenon in which the electrical properties, mechanical properties, and the like of the dielectric gradually deteriorate over time in the long-term operation. The main forms of aging are electrical aging, heat aging and environmental aging.
