Problems solved by technology

Due to the wide variety of online monitoring devices in China, the technical level is uneven, and some devices have not been strictly inspected when they leave the factory due to problems in the design or manufacturing process. As a result, the test data and the laboratory are quite different, which not only cannot truly reflect the operation status of the transformer, but also adds serious safety hazards to the operation of the power grid.

Description

technical field [0001] The invention provides a transformer oil mother liquor dilution method and a sample preparation device thereof, belonging to the field of transformer oil sample preparation devices. Background technique [0002] The transformer is one of the most important equipment in the power system, and its operation status will directly affect the reliability of power supply. With the rapid development of the national economy, society is increasingly dependent on power supply. Therefore, the safe and reliable operation level of transformers should be improved. is of great significance. Due to the influence of temperature, electric field, oxygen and the catalysis of copper, iron and other materials, the insulating oil and solid insulating materials inside the transformer during operation will undergo aging and decomposition reactions with the increase of operating time, in addition to generating a certain amount of acid, grease and sludge In addition to other degr...
