Abstract

The invention discloses a method of determining insulation characteristics of transformer oil. The method particularly comprises the following steps: 1) a transformer oil sample containing copper and iron metal particles and silica nonmetallic particles is prepared; 2) an insulation characteristic test is carried out on the transformer oil sample; 3) a fuzzy relation between particle pollutants in the transformer oil and the insulation characteristics of the transformer oil is built; 4) after the particle pollutants in the to-be-tested transformer oil are detected, the insulation characteristics of the transformer oil are analyzed and judged according to the fuzzy relation between the particle pollutants in the transformer oil and the insulation characteristics of the transformer oil. The fuzzy identification technology is used for determining the insulation characteristics of the transformer oil, determination can be realized without complicated test operation, human factor influences during the test process can be avoided, and the accuracy and the effectiveness of determining the insulation characteristics of the transformer oil are improved.

Description

Technical field [0001] The invention is a novel method for determining the insulation characteristics of transformer oil, and particularly relates to the technical field of determining the insulation characteristics of transformer oil. Background technique [0002] Transformer oil is an important insulating medium in power equipment, and its insulation properties are its most important properties. Breakdown voltage is an important electrical performance index that characterizes transformer oil, which can directly reflect whether there are polar impurities in transformer oil. Transformer oil is inevitably contaminated during production and operation, such as fiber particles, carbon particles, and metal particles such as insulating paper in transformers. Especially metal particles have a direct impact on the breakdown voltage of the oil. Depending on the content of copper and iron particles, the degree of impact on performance indicators such as oil breakdown voltage and the mechan...
