Abstract: Transformer plays a vital role in production and living, transformer oil temperature affects the various working parameters of the transformer, transformer oil temperature must be controlled in a certain temperature to ensure its efficiency. In this paper, using temperature sensor for temperature acquisition work, use of 51 single-chip microcomputer for data processing unit and control unit to control the oil temperature of transformer to solve the problem of transformer oil temperature is too high. This paper in Protues simulation processing, using DS18B20 as temperature sensor, simulated the temperature detection, temperature setting, temperature control and alarm function. Using this scheme not only reduces the maintenance cost of transformer, and improve the working stability of the transformer, prolong the service life of the transformer.
