Resumo: The power transformers have a high importance for the eletric power system, allowing the transmission of huge amounts of energy for big lengths and reduces losses. Althought the transformers have a high eficiency, a small part of process energy are converted to losses, resulting a rise of temperature on device. The problem associated to the rise of temperature is the fact of increase the agging of solid insulation, reducing the lifetime. This study show a metodology of temperatures and oil flow calculation for the radiator and the determination of the temperature disc-to-disc in the widings, both based on the geometry of the device. The calculation techniques resulted of this two methodologies possibilitated the criation of two algorithmics for the power transfrom analysies: One focusing in the radiator and other, the widing. For validation of this metodologies was used finites elements simulation, with the porpuse of compare the temperatures of top, botton and hotspot of tranformers.

Embora os transformadores tenham uma eficiência elevada, uma parcela da energia processada é convertida em perdas, resultando no aquecimento do dispositivo. O problema associado a elevação da temperatura está no fato de acelerar o processo de degradação da isolação sólida, reduzindo a sua vida útil. Neste trabalho é apresentado uma metodologia de cálculo das temperaturas e vazões do radiador e outra para a determinação das temperaturas disco-a-disco no enrolamento, ambas baseadas nas geometrias do dispositivo. As técnicas de cálculo resultante destas metodologia possibilitaram a criação de dois algoritmos para análise do transformador: um focado no radiador e outro para o enrolamento. Para validação da metodologia foram utilizadas simulações em elementos finitos, com o objetivo de comparar as temperaturas de topo, base e hotspot do transformador.porUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia ElétricaUFSMBrasilEngenharia ElétricaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessTransformador de potênciaModelo térmico-hidráulicoSimulações em elementos finitosPower tranformerThermic-hydraulic modelHotspotFinites elements simulationCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAMetodologia de análise térmica e hidráulica em transformadores de potênciaMethodology of thermal and hydraulic analysis in power transformersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMarchesan, Tiago Bandeirahttp://lattes.cnpq.br/2318413245910780Bender, Vitor Cristianohttp://lattes.cnpq.br/6015559740622811Falcão, Carlos Eduardo GuexSilva, Renato Alves dahttp://lattes.cnpq.br/5372002792799857Barth, Nórton Daniel3004000000076006006006006006000197cd95-ed8b-4ca0-89af-e654162d964db7d9553b-973c-4b7e-b51a-3429aaf744d95f52d2db-5330-4144-a9c3-b8092afa9cb0930072f1-5e4c-4c3e-bc0e-07871cc658f4be9a9bb3-65ca-4ce0-8d81-a47458a0e7a8reponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
