Evaluation of the use of a vegetable oil in distribution transformers Evaluación del uso de un aceite vegetal en transformadores de distribución

Abstract

Since the start of transformers immersed in refrigerating liquid, the fluid traditionally used has been mineral oil. However, in recent decades, efforts have been joined in the search for alternatives with a lower environmental impact and which also satisfy the technical requirements of insulation and refrigeration in the transformers. Currently, insulating vegetable oils are available in the market, which may have lower environmental impact during their use and final disposition; nevertheless, their high cost and short time of use have limited their massive application. This work presents the thermal behavior evaluation of two distribution transformers at different powers immersed in dielectric vegetable oil, comparing their performance with that of two constructively equal transformers immersed in mineral oil. The results obtained reveal that the transformers comply with the requirements of existing standards.Desde los inicios de los transformadores inmersos en líquido refrigerante, el fluido empleado por tradición ha sido el aceite de origen mineral. Sin embargo, en las últimas décadas se han unido esfuerzos en la búsqueda de alternativas que tengan un menor impacto en el medio ambiente y que a su vez satisfagan los requerimientos técnicos de aislamiento y refrigeración en los transformadores. Actualmente se encuentran en el mercado aceites aislantes de origen vegetal que pueden tener un menor impacto ambiental durante su uso y disposición final; no obstante, su elevado costo y su poco tiempo de uso han limitado su aplicación masiva. En este trabajo se presenta la evaluación del comportamiento térmico de dos transformadores de distribución de diferente potencia inmersos en aceite dieléctrico de origen vegetal y se compara su desempeño con el de dos transformadores constructivamente iguales inmersos en aceite mineral. Los resultados obtenidos revelan que los transformadores cumplen con los requerimientos de la normatividad existente.
