Problems solved by technology
[0003] At present, most of the studies on the impact of acid on silicone rubber have not been combined with the actual acid rain and the amount of acid rain has not been quantified, especially in acid rain areas. Predict the impact of acid rain on silicone rubber under a certain operating time of composite insulators, which leads to the inability to evaluate and guarantee the safety of the external insulation of composite insulators during long-term operation

Abstract
The invention discloses a method for simulating acid rain accelerated aging, which comprises the following steps of: A, selecting an area with acid rain as a research object, and obtaining an annual acid rain pH mean value and an annual rainfall day number t1 in recent n years through an environmental condition announcement and related meteorological data; B, according to the annual acid rain pH mean value of the region, converting the annual acid rain pH mean value into an annual average H<+> concentration c1; C, designing the acid rain concentration c2 for the test according to the annual average H<+> concentration c1, and preparing an acid solution; D, treating the to-be-detected material in the acid solution for a period of time t2; and E, testing the performance of the to-be-tested material. The method can achieve the purpose of approximately evaluating the effect of acid rain equivalent to different years on the umbrella skirt of the composite insulator through the effect of an acid solution with a certain concentration in a certain time period. The invention also discloses an application of the method for simulating acid rain accelerated aging in silicone rubber aging.
Description
technical field [0001] The invention relates to the technical field of material detection methods, in particular to a simulated acid rain accelerated aging method and its application. Background technique [0002] Composite insulators are important insulating components in power systems. The outer insulating silicone rubber has received extensive attention due to its excellent hydrophobicity, hydrophobic migration, and pollution flashover resistance, and the outer insulation acts as a barrier for the inner insulation. The operating life of the insulator plays a key role. During the operation of the composite insulator, its outer insulating silicone rubber is directly exposed to the atmosphere, and it will inevitably come into contact with acid rain. Therefore, it is necessary to pay attention to the possible impact of acid rain on the outer insulation of silicone rubber. [0003] At present, most of the studies on the impact of acid on silicone rubber have not been combined...
