Description
technical field [0001] The invention belongs to the technical field of rubber material aging, and in particular relates to an artificial simulation system and a simulation method for the aging process of silicone rubber in an acidic corrosion environment. [0002] technical background [0003] In recent years, composite insulators, RTV creepage skirts, and composite insulating bushings have been widely used in AC and DC transmission networks because of their good electrical and mechanical properties. The aging problem in the application process of composite insulating materials is a severe challenge to the safe operation of the power grid, especially in harsh environments such as high corrosion and strong ultraviolet rays, the aging problem is more prominent. With the aggravation of environmental pollution, composite insulators on transmission lines have long suffered from acid rain pollution and the corrosion of acidic chemical pollution in industrial cities. Under the influ...
