Análisis de la Eficiencia en la Disipación de Calor de la Bobina de Baja Tensión de un Transformador de Potencia Funcionando en Modo ONAN/ONAF
Bibliographic record
Abstract
La vida útil y la fiabilidad de un transformador de potencia dependen en gran medida de los modos de refrigeración, ya que el calor excesivo es la principal causa del deterioro de la vida útil del aislamiento. Por esta razón, el enfriamiento óptimo es necesario para evitar la degradación tanto del aceite como del papel que constituyen el aislante en las bobinas. Los principales objetivos de este trabajo son analizar la capacidad de enfriamiento del actual diseño de la bobina de baja tensión de un transformadores de potencia de 66 [MVA], 225/26.4 [kV] funcionando en modo ONAN/ONAF de la empresa Hydro-Québec. A partir de ello, se presentarán mejoras en el diseño actual de la geometría del canal y se evaluará en relación a otro diseño de canales. La distribución de temperatura, la velocidad del aceite y la eficiencia en la capacidad de extracción del calor se estimarán a partir de los resultados obtenidos mediante simulaciones CFD en paralelo con el software Code_Saturne basado en volúmenes finitos.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
